Why coronavirus cannot spread through the air

There’s no transmission risk for everyday people from COVID-19 virus-laden mist

Is COVID-19 an airborne disease? No, it is not.

The new coronavirus can remain suspended in the air for hours, but it cannot infect others under normal conditions.

So there’s no reason to be alarmed — unless you are a medical professional dealing directly with COVID-19 patients.

The virus is typically transmitted through respiratory droplets, but a new study published in the New England Journal of Medicine indicated that it can remain in the air for up to three hours.


Lab tests have shown that aerosolised coronavirus particles (a fine mist or spray) can remain in the air for hours under certain conditions. But those conditions are rare.

I think the answer will be, aerosolisation occurs rarely but not never. You have to distinguish between what’s possible and what’s actually happening.
- Dr Stanley Perlman, University of Iowa, microbiologist and physician
“I think the answer will be, aerosolisation occurs rarely but not never,” said microbiologist and physician Stanley Perlman of the University of Iowa. “You have to distinguish between what’s possible and what’s actually happening.”

No evidence of infection
There is still no evidence to suggest that the virus-infected mist could infect other people, like measles.


More research would be needed to determine that, said Jamie Lloyd-Smith, an ecology and evolutionary biology professor at the University of California, Los Angeles.

“If it could easily exist as an aerosol, we would be seeing much greater levels of transmission,” said epidemiologist Michael LeVasseur of Drexel University in Philadelphia, Pennsylvania.

“And we would be seeing a different pattern in who’s getting infected. With droplet spread, it’s mostly to close contacts. But if a virus easily exists as an aerosol, you could get it from people you share an elevator with.”
In lab experiments, scientists transformed coronaviruses into a mist by putting them through a nebuliser.

The coronavirus not only survived in aerosolised particles for three hours, but they were also able to infect cells and replicate.

Perlman feels such a situation may only occur during procedures such as intubation. That has prompted the World Health Organisation (WHO) to issue new “airborne precautions” for medical professionals.

Advisory to medical professionals
Dr Maria Van Kerkhove, head of emerging diseases and zoonosis unit at the WHO, said health care workers were told to protect themselves.

The recommendations include the use of respirators, N95 masks, gowns, and extensive protection when performing some procedures on infected patients.

“When you do an aerosol-generating procedure like in a medical care facility, you have the possibility to what we call 'aerosolise' these particles, which means they can stay in the air a little bit longer,” Van Kerkhove said.

Droplets are the worry
A normal person shouldn’t be concerned, Van Kerkhove added.

Because in real-life conditions, virus in the air will get diluted quickly.

But if you're in an enclosed space, the virus could hang out in the air for a while.

“We’ve seen no evidence that aerosolised virus is the primary transmission risk for everyday people in everyday settings,” said Dylan Morris of Princeton University in New Jersey, US.

“One should not rule anything out categorically with a novel, still-poorly-understood virus.”

That should quell any fears on airborne transmission. Droplets are more worrying. So let’s keep washing our hands.

Coronavirus: Cases balloon in Europe as global deaths cross 13,000

305,000 people have been infected across world as pandemic shows no signs of abating

Dubai: Coronavirus cases ballooned in Europe, prompting more lockdown measures to try to slow the spread. New Jersey’s governor followed four other US states that have imposed unprecedented restrictions. Australia announced it was shutting a large array of businesses from Monday.
More than 305,000 people have been infected across the world and more than 13,000 have died according to a Reuters tally.
Europe
In its latest desperate effort to halt the epidemic the Italian government ordered that all businesses must close until April 3, with the exception of those essential to maintaining the country’s supply chain.
Italy recorded a jump in deaths from coronavirus of almost 800 on Saturday, taking the toll in the world’s hardest-hit country to almost 5,000.
Spain extended for another 15 days a 15-day state of emergency imposed this month to try to curb the spread. Spain’s death toll soared to 1,720 on Sunday from 1,326 the day before, according to multiple media outlets citing the latest health data.

British Prime Minister Boris Johnson said the country’s National Health Service (NHS) could be “overwhelmed” by the coronavirus like the Italian health system in just two weeks.

Americas
Nearly 1 in 4 Americans were under orders to close up shop and stay at home on Saturday. At least 23,941 cases of the novel coronavirus have been reported in the United States and 306 people have died from the COVID-19 disease as of Saturday evening, according to a Reuters tally of state and local government websites.

Bolivia’s interim government announced it would postpone presidential elections originally slated for May 3 and institute a mandatory countrywide quarantine for 14 days.
Brazil’s largest state Sao Paulo will essentially shut down for two weeks to help fight the coronavirus, its governor said on Saturday, as President Jair Bolsonaro said again that “hysteria” over the outbreak could cause more harm than the virus itself.

Asia
Hundreds of millions of Indians stayed indoors on Sunday, heeding Prime Minister Narendra Modi’s appeal to citizens to self-isolate. At least 341 people have so far contracted the disease and four deaths have been reported in India due to the coronavirus, according to official data on Sunday. China on Sunday reported 46 new cases of coronavirus, the fourth straight day with an increase, with all but one of those imported from overseas, and further stepped up measures to intercept cases from abroad.

Australian Prime Minister Scott Morrison on Sunday ordered many venues, including pubs, casinos, gyms and cinemas, to close from midday Monday to combat coronavirus after many people appeared to disregard health warnings and congregated in large numbers in recent days.

Members of a South Korean church scuffled with police on Sunday, media reported, as government restrictions on religious services and other gatherings took effect.

Middle East and Africa
Iran’s death toll has reached 1,685 with 129 deaths in the past 24 hours, the health ministry’s spokesman told state TV on Sunday, adding that the total number of infected people in Iran had reached 21,638.

Iran’s Supreme Leader Ayatollah Ali Khamenei said the United States’ offer to help Iran in its fight against the pandemic is strange.

Oman on Sunday banned public gatherings in the Gulf Arab state, limited staffing at state entities and shut currency exchange bureaus.

Angola, Eritrea and Uganda confirmed their first cases of coronavirus, while Mauritius recorded its first death as the virus spreads across Africa.

Economic fallout
Republicans and Democrats in the US Senate scrambled on Saturday to complete a deal on a $1 trillion-plus bill aimed at stemming the coronavirus pandemic’s economic fallout for workers, industries and small businesses.

Companies should not publish preliminary financial statements for at least two weeks to better assess how the coronavirus epidemic is affecting their business, Britain’s Financial Conduct Authority said on Saturday.

A Chinese central bank official called on Sunday for stepped up global policy coordination to manage the economic impact of the coronavirus outbreak, and said Beijing’s recent policy measures were gaining traction while it had capacity for further action.

A wave of credit rating downgrades in the corporate sector risks deepening a funding crisis for company bosses and spreading it to other markets.

Germany is readying an emergency budget worth more than 150 billion euros ($160 billion) to shore up jobs and businesses at risk from the economic impact of the coronavirus outbreak, the finance minister said on Saturday.

Amazon.com Inc said it is raising overtime pay for associates working in its U.S. warehouses as the world’s largest online retailer tries to meet the rapidly growing demand for online shopping from consumers stuck at home.

Sports
Tokyo 2020 organisers have started drafting possible alternatives to holding the Olympics this summer, two sources familiar with the talks said, in contrast to the Japanese government’s stance that postponement is not an option.

Multiple sports events have been cancelled or postponed.

15 interesting things to do while at home, for little to no cost!


1. Clear the clutter: Is there a storage cupboard that needs cleaning? Do you need to sort your wardrobe? Is the kitchen cabinet a mess? This weekend, take some time to clear the cluttered spaces in your home. Organise what you need and the things you can do away with and ‘Marie Kondo’ your home. If you live with family (or a roommate), you can get other members involved, assign tasks and get the job done!


2. Read a book: Our daily hustle and bustle often leaves us with less room to do the things we like and enjoy. You can take this opportunity to catch up on some reading. With the advancement of technology, everything is at the click of a button. You can read a book online or order one from your nearest book shop, whichever you prefer.


3. Catch up on sleep: Most people complain about not getting enough sleep during a work week. From shuttling between the daily nine to five to meeting up with friends or spending time with family after, one often compromises on a good eight-hours of sleep. Sleep is important to keep healthy and build immunity, and with the current pandemic, it is essential you get some snoozes in, and relax.


4. Make a long-distance call: If you live away from family or have been meaning to catch up with a long-distance friend, do it! Chances are, they are probably social distancing too and could use the company.


5. Cook something new: Use the ingredients you have on hand and try a new recipe. You can perfect your favourite pasta dish or try making a dish from another cuisine. The perks? If it turns out well, you get to eat it!


6. Movie binge: Whichever video streaming platform you use to catch up on movies, prepare a list of films that have more than one sequel and binge watch them all. Make yourself some microwavable popcorn and you won’t even miss going to the cinema.


7. Meditate: With time on your hands, take out a few minutes in the day to meditate. If you don’t know how to, YouTube comes in handy. There are plenty of videos and tutorials that take you, step by step, through the process of meditation. If you enjoy it, it could become a daily habit.


8. Write a journal: Journal writing is considered to be therapeutic. Maintaining a journal helps people organise their thoughts, keep track of daily activities, and note down important events. Write down what you manage to accomplish in the day or the things you are grateful for. It could be a page or a few points, but note down the activities you get up to doing in the day. This activity can be fun for children as well. They should be encouraged to maintain a personal journal, which they can decorate and fill in daily.


9. Arts and Crafts: Brighten up your day with an arts and crafts session with paraphernalia like paper, coloured pens, cardboard boxes and other materials lying around at home or available at the nearest supermarket. From do-it-your self-boxes, quirky bookmarks, to mindful colouring pages for children and adults, there’s a lot one can do with the help of the internet. Pick up Origami by watching tutorials, or learn to paint with watercolours, there’s something for everyone.


10. Grow plants: Do you have a green thumb? Find out. Grow a few small, easy-to-maintain plants like sprouts and herbs. If you already have a plant garden, check up on your plants. Make sure they are getting enough water and sunlight. This activity could be very educational for young children who can learn more about the anatomy of plants and the process of germination. Just remember to wash your hands afterwards!



11. Play games: If you’re competitive and enjoy games that stimulate your mind, challenge yourself. See how many words you can come up with in a minute. Try a Sudoku puzzle and attempt tougher levels. Do the crossword in the Gulf News print edition. If you need ways to keep your children entertained, board games come to the rescue. Play a game of scrabble, Jenga or Pictionary with the family. If your team wins, remember only elbow bumps allowed.


12. Work out: Gyms are closed around the UAE but that doesn’t mean you can’t work out at home. Put on some good music, and do some jumping jacks and stretches. There are many YouTube videos you can lean to for help if you need motivation and technique. You can even do this with the children. (Don’t attempt something too strenuous and before you begin a new fitness routine, always consult your doctor).


13. Take an online class: Since people have been advised by the UAE government to stay indoors as much as possible, one can take an online class from the comfort of your home. And they are free. all you need is a little research. From public speaking classes, to becoming a social media master, make use of your time and learn something new.


14. Learn steps to your favourite song: If you’re trying to master K-Pop band EXO’s crazy dance moves or learn Bollywood actress Nora Fatehi’s break-dancing routine from her latest film, now’s your chance. Put on some music and get to it.

15. Be active on social media: While you’re supposed to socially distance yourself, you can still update your status, create TikTok videos, use Snapchat filters and be online with your friends and family. Share pictures, use different selfies and share it with your friends. Keep your loved ones in the loop and have fun.

کورونا: وینٹیلیٹر کی ضرورت کب پڑتی ہے اور پاکستان میں کتنی مشینیں دستیاب ہیں؟

کورونا وائرس سے متاثر ہونے والے زیادہ تر افراد کے بارے میں کہا جا رہا ہے کہ بغیر کسی پیچیدگی کے ان کی صحت بحال ہو جاتی ہے۔ تاہم متاثرہ افراد کی ایک مخصوص شرح میں طبی پیچیدگیاں ہو سکتی ہیں۔

تاحال سامنے آنے والے مشاہدات کے مطابق ان میں وہ افراد زیادہ شامل ہیں جو 60 سال سے زیادہ عمر کے ہیں یا وہ جن میں پہلے سے کوئی مرض پایا جاتا ہے۔ اس صورت میں ان متاثرہ افراد کو طبی امداد کی ضرورت ہوتی ہے۔

کووِڈ-19 کے بارے میں تاحال زیادہ معلومات میسر نہیں تاہم اس کی ایسی علامات جن کو خطرناک قرار دیا جا رہا ہے ان میں سانس کی روانی میں تعطل کی شکایات اور نظام تنفس میں انفیکشن شامل ہیں۔

مگر کیا ایسے تمام افراد کو وینٹیلیٹر یا مصنوعی نظامِ تنفس کی بھی ضرورت ہو گی اور کیا کورونا کی صورتحال میں پاکستان خصوصاً صوبہ پنجاب میں یہ موزوں تعداد میں دستیاب ہیں بھی یا نہیں؟
لاہور کی یونیورسٹی آف ہیلتھ سائنسز کے وائس چانسلر پروفیسر ڈاکٹر جاوید اکرم کے مطابق 'کوئی بھی شخص جس میں بیماری شدت اختیار کر جائے اور مریض سانس ہی نہ لے سکے تو اسے وینٹیلیٹر پر ڈالنے کی ضرورت پڑتی ہے۔'

کووِڈ-19 کے مریض میں یہ صورتحال پیدا ہو سکتی ہے۔ لیکن وینٹیلیٹر پہلے ہی پاکستان میں ضروت سے انتہائی کم تعداد میں میسر ہیں۔ وینٹیلیٹر پاکستان میں مقامی طور پر تیار نہیں ہوتے اور درآمد کرنے پڑتے ہیں اس لیے یہ مہنگے ہیں۔

عام حالات میں کسی بھی ہسپتال میں ضرورت کے مطابق وینٹیلیٹر کے استعمال کو ڈھالا جا سکتا ہے لیکن کورونا وائرس کے ممکنہ پھیلاؤ کا خدشہ ایک غیر معمولی صورتحال ہے۔

وائس چانسلر ہیلتھ سائنسز یونیورسٹی جاوید اکرم کے مطابق فی الوقت صورتحال زیادہ خراب نہیں 'مگر اس میں زیادہ سنگین ہونے کے تمام تر امکانات موجود ہیں۔'
متاثرہ افراد کو وینٹیلیٹر کی ضرورت کب پڑے گی؟
پنجاب حکومت نے کووِڈ-19 کے حوالے سے جو رہنما اصول ترتیب دیے ہیں ان میں کسی مشتبہ مریض کو سنبھالنے کا طریقہ کار بھی شامل ہے۔ اس کے مطابق مشتبہ مریض کو ماسک دے کر مخصوص کی گئی جگہ پر پہنچایا جائے گا۔

یہاں اس کا فلو وغیرہ کا علاج شروع کیا جائے گا اور ساتھ ہی اس کے جسم سے حاصل کیے گئے نمونے کووِڈ-19 کے ٹیسٹ کے لیے بھجوا دیے جائیں گے۔

اس دوران اس میں علامات میں بدتری کی نشانیوں کا جائزہ لیا جائے گا جن میں سیپسِس یا سیپٹک شاک اور ہائیپوکسیا وغیرہ شامل ہیں۔

اگر اس میں علامات کے بگڑنے کے شواہد موجود نہیں تو اسے علیحدگی میں رکھا جائے گا اور ہیں تو اسے ہائی ڈیپینڈنسی یونٹ (ایچ ڈی یو) بجھوا دیا جائے گا۔ اب ان دونوں جگہوں پر مریضوں کا مشاہدہ کیا جائے گا کہ کیا ان کی علامات میں بہتری آ رہی ہے یا نہیں۔

اگر مریض کی حالت میں بہتری نہیں آ رہی یعنی اس کی نبض کی رفتار 100 سے زیادہ ہے اور بلڈ پریشر 100 سے کم ہے یا اندرونی اعضا کے غیر فعال ہونے کا خطرہ ہے تو اسے وینٹیلیٹر سپورٹ پر لگایا جائے گا۔

وینٹیلیٹر کیا ہے اور کیا کرتا ہے؟
وینٹیلیٹر بنیادی طور پر ایک ایسی مشین ہے جسے مصنوعی نظامِ تنفس کہا جا سکتا ہے۔ یہ انسان کے پھیپھڑوں میں آکسیجن داخل کرتا ہے اور جسم سے کاربن ڈائی آکسائیڈ کا اخراج کرتا ہے۔

یہ بذاتِ خود کسی بیماری کا علاج نہیں بلکہ کسی علاج کے دوران اس وقت استعمال کیا جاتا ہے جب مریض کو سانس لینے میں دشواری ہو یا وہ خود سے سانس ہی نہ لے پائے۔ ان میں نمونیا بھی شامل ہے جو کورونا کی بدتر علامات میں سے ایک ہے۔

ہسپتال میں ماہر ڈاکٹروں کی زیرِ نگرانی وینٹیلیٹر کو ایک ٹیوب کی مدد سے مریض کے نظامِ تنفس سے جوڑ دیا جاتا ہے۔ زیادہ تر وینٹیلیٹرز کو چلنے کے لیے بجلی کی ضرورت ہوتی ہے تاہم چند کو بیٹری کی مدد سے بھی چلایا جا سکتا ہے۔

وینٹیلیٹر کا مقصد یہ ہوتا ہے کہ مریض کو اس وقت تک سانس کی فراہمی ممکن بنائی جاتی رہے جبکہ تک وہ اس کو لاحق مرض سے باہر نہیں آ جاتا۔ کسی متعدی بیماری کی وجہ سے یہ دورانیہ چند دنوں پر بھی محیط ہو سکتا ہے۔
کیا پاکستان میں وینٹیلیٹر آسانی سے میسر ہیں؟
ہیلتھ سروسز یونیورسٹی کے وائس چانسلر ڈاکٹر جاوید اکرم کے مطابق وینٹیلیٹر مقامی طور پر پاکستان میں تیار نہیں ہوتے اور انھیں درآمد کرنا پڑتا ہے، اس لیے ان کی قیمت کافی زیادہ ہوتی ہے۔

'ایک عام چھوٹا سا وینٹیلیٹر بھی 10 سے 15 لاکھ سے شروع ہوتا ہے اور 50 لاکھ روپے مالیت تک بھی چلا جاتا ہے۔' ان کو چلانے کے لیے بجلی کا خرچ اس کے الگ ہے۔ شاید یہی وجہ ہے کہ ڈاکٹر جاوید اکرم کے مطابق پاکستان میں 'پہلے ہی وینٹیلیٹرز ضرورت سے انتہائی کم ہیں۔'

وینٹیلیٹرز کی عدم دستیابی کی صورت میں جو متبادل طبی طریقہ استعمال کیا جاتا ہے، ڈاکٹر جاوید اکرم کے مطابق وہ قابلِ بھروسہ نہیں ہے۔

کورونا کی صورتحال میں کتنے وینٹیلیٹر میسر ہوں گے؟

کورونا کے ممکنہ پھیلاؤ کو روکنے کے لیے حکومتِ پنجاب نے صوبے کے تمام اضلاع کے اندر مختلف ہسپتالوں میں کورونا کے ہائی ڈیپینڈنسی یونٹ قائم کیے ہیں جن میں آئسولیشن سنٹر بنائے گئے ہیں۔

محکمہ پرائمری اینڈ سیکنڈری ہیلتھ پنجاب کے کورنا کے حوالے سے کی جانے والی تیاریوں پر مشتمل کتابچے میں دیے گئے حالیہ اعداد و شمار کے مطابق لاہور کے سروسز ہسپتال میں قائم آسولیشن سنٹر کے پاس چھ سے آٹھ وینٹیلیٹر موجود ہیں۔

سب سے زیادہ گجرات کے عزیز بھٹی شہید ٹیچنگ ہسپتال میں 15 وینٹیلیٹر موجود ہیں۔ اسی طرح بہاولپور میں سات، راولپنڈی میں چھ سے آٹھ، اوکاڑہ میں آٹھ، میانوالی میں پانچ، رحیم یار خان میں چھ جبکہ زیادہ تر جگہوں پر ایک یا دو وینٹیلیٹر موجود ہیں۔

رپورٹ کے مطابق بھکر، جھنگ، قصور اور لودھراں کے ہسپتالوں میں قائم ہائی ڈیپینڈنسی یونٹس میں ایک بھی وینٹیلیٹر موجود نہیں ہے۔
کورونا کے مریضوں کی اس وقت صورتحال کیا ہے؟
پنجاب حکومت کے مطابق صوبے میں کورونا کے مصدقہ مریضوں کی تعداد منگل کی رات تک 25 سے تجاوز کر چکی تھی ان میں وہ زائرین بھی شامل ہیں حال ہی میں ایران سے واپسی پر تفتان کے مقام پر قرنطینہ میں 14 روز گزارنے کے بعد حال ہی میں پنجاب میں داخل ہوئے تھے۔

حکومت کے مطابق 700 سے زائد ان تمام زائرین کو ڈی جی خان میں قائم قرنطینہ میں رکھا گیا ہے جہاں غازی یونیورسٹی میں 1740 افراد کی گنجائش کا قرنطینہ قائم کیا گیا تھا۔ تاہم پنجاب کے وزیرِاعلٰی عثمان بزدار کے مطابق 1276 مزید زائرین پنجاب میں داخلے ہوں گے جنہیں قرنطینہ میں رکھا جائے گا۔

تاہم اس صورتحال میں دیکھنا یہ ہو گا کہ آنے والے دنوں میں مخلتف ہسپتالوں میں قائم ہائی ڈیپینڈنسی یونٹس پر دباؤ کتنا بڑھے گا۔ اس کے بعد یہ اندازہ لگایا جا سکے گا کہ کس مقام پر کتنے وینٹیلیٹرز کی ضرورت ہو گی۔

حکومت کیا کر کر رہی ہے؟
منگل کی شب عوام سے خطاب کرتے ہوئے وزیرِاعظم پاکستان عمران خان نے اس امر کا اعتراف کیا کہ کورونا کی صورتحال میں 'حکومت کو اندازہ تھا کہ کسی ممکنہ پھیلاؤ کی صورت میں انھیں دیگر سہولیات کے ساتھ وینٹیلیٹرز کی کمی کا سامنا بھی ہو گا۔'

ان کا کہنا تھا کہ اس امر کو دیکھتے ہوئے حکومت نے پہلے ہی سے چین سے رابطہ کر رکھا تھا۔ چین سے حاصل کی جانے والی طبی سہولیات میں وینٹیلیٹرز کا حصول بھی شامل ہے۔

8 best tips for how to stay happy in troubling times

By dwelling less on stress and reflecting on the positives, BBC Future’s guide to happiness will help you to feel less overwhelmed by world events.
With the unfolding global coronavirus pandemic leading to people being confined to their homes, borders being shut and economic instability, it can be hard not to feel overwhelmed by the state of the world at the moment. The good news? Even in times of stress and anxiety, you can take proactive steps to lift your mood.

The science of emotions is incredibly complicated, but it is also well-studied. Over the years, BBC Future has interviewed dozens of world-leading experts in psychology who shared with us practical, everyday tips for coping better with stress. We recently trawled through the research. Here are some of the top tips we found – some of which may surprise you.

1. Distract yourself.

It’s easy to run over and over the topic that’s stressing us out, whether that’s the new coronavirus outbreak, the state of the climate or something else. But stopping people from ruminating on a recent stressful event – by offering a distraction – can lower their blood pressure back to normal levels quicker than offering no distraction.

2. If you meditate, be aware that it might not work for everyone.

In times like these, many people might find meditation and mindfulness helpful. But others might not – for precisely the reason above. For some people, practicing stillness might simply invite rumination. It can be difficult not to think about stressful events when trying to clear our minds. This may be why evidence for the benefits of mindfulness and meditation is patchy. For those people, a more compelling distraction than meditation might be required.

3. Reframe the situation.

How we interpret our emotions is largely down to how they’re framed – in other words, the context. While talking about his 2017 book Happy, Derren Brown gives the example of a tennis player going into a match thinking “I must win”. If they set an expectation that winning is everything, if they start to lose, they feel like an abject failure. This is a trap perfectionists tend to fall into, and it’s why perfectionists tend to respond with more guilt, shame and anger when they feel they aren’t succeeding. They may even be more likely to give up.

The player who goes into a match thinking “I will play the best I can”, however, believes that they are less hurt by losing, so long as they are doing their best. The signs of failure are interpreted differently by both players based on the expectations that they set for themselves.

It’s worth thinking about how you can apply this in your daily life: can each moment or day be about doing the best you can in a stressful situation (“I will practice proper hygiene and social distancing”), rather than focusing on an outcome out of your control (“I will not and cannot get sick”)?

That control part is key. Stressful situations are often beyond our control, and we create anxiety and worry when we try to control what we can’t. Focusing on what can be controlled, on the other hand, can decrease feelings of anxiety.

4. Don’t obsess over being positive or happy.

This one may seem counterintuitive: it can be a bad idea to chase positive emotions. Actively pursuing happiness can lead to the reverse effect. For one thing, the more we focus on our own happiness, the less we focus on the happiness of the people around us, which has been shown to contribute to feelings of isolation and disconnection. There is also a link between searching for happiness and feeling that time is slipping away.

And again, if you’re focused on an outcome like “I must feel happy”, you may feel worse about yourself if you don’t succeed – even though it’s perfectly natural to have a more difficult time feeling happy in stressful times.

We can improve our mood by focusing on the small things that bring happiness to us each day
5. Focus on the small things.

It may be wise, then, to spend less time trying to become happy, and focus more on the little things that make us happy.

In her book Ten Minutes to Happiness, Sandi Mann, a lecturer at the University of Central Lancashire, advocates keeping a daily journal. Her strategy is based on “positive psychology” – a well-established area of psychology that suggests we can improve our mood by focusing on the small things that bring happiness to us each day. Mann says that answering the following six questions, a task that should only take 10 minutes, can help us to find more happiness in life.

1. What experiences, however mundane, gave you pleasure?

2. What praise and feedback did you receive?

3. What were the moments of pure good fortune?

4. What were your achievements, however small?

5. What made you feel grateful?

6. How did you express kindness?

The benefits of keeping a short journal like this are two-fold. When we write, it helps to remind us of the small things that brought us happiness. It also provides us with an archive of everything that has made us happy in the past, which we can reflect on at a later date.

6. Clean up – maybe.

Should you find yourself quarantined, take this opportunity to clean your house. "Kondo-ing" your home has been shown to carry many benefits. Clutter makes it harder for us to focus on tasks, so should you find yourself working from home, a quick tidy up might help you to get your jobs done. A messy bedroom has been linked with difficulty sleeping, and messy kitchens with making poor health choices, like reaching for junk food. If you are going to be spending more time in the house, it will be worth your while getting your living spacesin order.

However, de-cluttering is not for everyone. Hoarders use physical objects to reinforce feelings of comfort and security. For those people, tidying up activates the brain’s pain-processing regions.

7. Balance your social media consumption.

Social media might appear to be filled with bad news, but for many it is also a key way to stay updated and connected with friends and loved ones. Keeping your phone out of your bedroom, or self-imposing screen-free time, can help you to balance the negativity with the benefits social media brings.

8. Get out of town.

If you live in a city, another option might be to leave it behind for a short while – only if you can do so while maintaining safe social distancing and safeguarding your, and others’, health.

People in cities suffer from disproportionately high rates of mood disorders. Meanwhile, views of water and blue skies can undo the effects of ill moods. As little as “a 20 to 30% increase in blue space visibility could shift someone from moderate distress into a lower category”, suggests one paper from 2016.

Interestingly, the effect is not seen with green space, so the seaside will be better for you than the country.

So the next time you find yourself worrying about the world, consider taking some of these steps instead of ruminating, refreshing your social media feeds or, perhaps for some, even meditating. Remember: emotions are what we make of them.

No, drinking water doesn't kill coronavirus

A rumour about Covid-19 has been spreading – that drinking water regularly and keeping your mouth moist can protect you. Here BBC Future examines the evidence.

First there was the bizarre suggestion that it can be cured with cocaine. After the erroneous idea circulated widely on social media, the French government had to quickly issue a statement saying that it’s definitely pas vrai. Then came the claims that avoiding ice cream could help, prompting Unicef to issue a statement that this is also not true. Finally the – extremely dangerous and also false – idea emerged that it can be prevented by drinking bleach.

Though the coronavirus pandemic started just a few months ago, it has already spawned an abundance of online fables and urban legends about how to evade it. One suggests that drinking water can help to prevent the infection. Here’s why that’s extremely unlikely.
The original posts shared on social media say that we should make sure our mouths and throats are always moist, and drink water every 15 minutes. The logic is that this will help to wash the virus down the oesophagus, so it that it can be killed by our stomach acid.

“This is just so simplistic, I can’t even get my head around it,” says Kalpana Sabapathy, a clinical epidemiologist at the London School of Hygiene and Tropical Medicine.

Sabapathy explains that infections often begin after we’ve been exposed to thousands or millions of viral particles, so sweeping a few down the oesophagus is unlikely to have much of an impact. “One gaping hole in it is the likelihood that you managed to flush all of them down into your stomach,” she says. “You would probably have already got them in your nostrils by then, for example – it’s not fool proof,” she says. And here lies another of the main flaws in the idea. Even if the virus hasn’t already managed to find its way inside the cells of your respiratory tract, it can also get into the body in other ways. While some people might become infected by touching their mouth with contaminated fingers, it can also enter the body by touching the nose or eyes.

As it happens, this is not thought to be the main route of transmission. Instead, the main risk is from breathing in tiny droplets containing thousands of viral particles after a person coughs or sneezes – either when they’re hot-off-the-press or have been lingering in the air hours afterwards. (Read more about how long the Covid-19 coronavirus can stay on surfaces and in the air.)
And there’s another reason the water-drinking technique might not work. You would think that, once a Covid-19 particle had made its way into your stomach, it would be killed immediately. After all, gastric acid has a pH of between one and three; it’s roughly as potent as battery acid, which is capable of dissolving steel. A few years ago, scientists invented a way to use it as a power source.

But the virus might be far more robust than this. After Mers emerged from Saudi Arabia in 2012, researchers discovered that the pathogen – which is a coronavirus and relative of Covid-19 – is “considerably resistant” to the slightly diluted acid that you would find in the stomach of a person who had recently eaten. They found signs that the virus had managed to colonise one patient’s gut, and showed that it can easily colonise cells from the intestine. The team speculated that it might be possible to become infected this way.

It’s not yet clear if this is also true for Covid-19. Some patients have been reporting symptoms such as nausea and diarrhoea, and now experts from China are warning that there are signs it can infect the digestive tract. According to one report, more than 50% of people with Covid-19 have the virus in their faeces, where it’s lingering long after it’s been cleared from the lungs.
Perhaps most compellingly, there hasn’t been any research looking into whether drinking water can prevent infection with Covid-19, so this technique is not based on science or fact – just wobbly theory. In fact, the only study that comes close is from 15 years ago.

The research looked at whether gargling with water might help to prevent respiratory infections, because the practice is popular in Japan. They found that, over a 60-day period, participants who gargled with water three times a day were indeed less likely to report respiratory symptoms than those who gargled with an antiseptic solution or who did neither. However, the findings don’t necessarily apply to Covid-19 – and it’s dangerous to assume that they do.

First, the study focused on infections of the upper respiratory tract, which mostly involve the sinuses, throat and, airways, while Covid-19 is also known to infect the lower respiratory tract, infiltrating the chest and lungs. Secondly, it’s worth noting that it was a relatively small study, in which the participants were asked to self-report their symptoms (rather than being assessed objectively) and knew which treatment group they were in. This kind of study is thought to be less reliable than the gold standard – a placebo-controlled randomised trial.

Sabapathy says that, though telling people to keep their mouths moist and drink water every 15 minutes might sound harmless, it’s important to squash this kind of misleading advice quickly.

The danger lies in the false sense of security that it provides. “People will think that by doing that, they're going to be OK,” she says. “It diverts from the much more important messages.”

The overwhelming evidence suggests that the best approach remains avoiding unnecessary social contact and washing your hands. So her advice is to put down the water and pick up the soap instead.

محمد حنیف کا کالم: غریب کورونا، امیر کورونا

اپنے محلے کے جنرل سٹور سے گھر کا سودا خریدتے ہوئے ایک صاحب کو دیکھا جو منرل واٹر کی پیٹیاں ذخیرہ کر رہے تھے لیکن مصر تھے کہ پاکستانی نیسلے نہیں چاہیے، وہ جو دبئی والا آتا ہے وہ چاہیے۔
جب جنرل سٹور والے نے بتایا کہ وہ دستیاب نہیں ہے تو وہ بھناتے ہوئے گاڑی کی چابی گھماتے ہوئے کسی بہتر سٹور کی جانب چل دیے۔
میرے محلے کے سٹور والی گلی میں ہی کراچی کا مشہور عوامی ہوٹل کیفے کلفٹن ہے۔ یہ اتنا عوامی ہے کہ عید کے دن بھی بند نہیں ہوتا۔ کراچی کی انتہائی کم ایسی جگہیں ہیں جہاں مزدور اور بابو ایک ساتھ بیٹھ کر چائے پیتے ہیں۔
یہاں پر صبح مفت ناشتے کا بھی انتظام ہوتا ہے۔ کئی سالوں سے دیکھ رہا ہوں کہ ایک پراٹھے اور چائے کے کپ کے لیے لگی لائن لمبی ہوتی جا رہی ہے۔ لوگ اپنے چھ بچوں کو بھی لاتے ہیں۔ ناشتے کا انتظار کرتے لوگوں کے حلیے سے پتا چلتا ہے کہ وہ محنت کش ہیں، بھکاری نہیں۔
ان میں وردیاں پہنے پرائیویٹ سکیورٹی گارڈز ہوتے ہیں، کبھی رکشہ چلانے والے اور ایک آدھ دفعہ تو میں نے پولیس والے کو بھی ایک ہاتھ میں بندوق اور دوسرے ہاتھ سے چائے پراٹھا پکڑتے دیکھا ہے جو کیفے کلفٹن کے ملازم کسی مخیر اور درد مند شہری کی ایما پر بانٹ رہے ہوتے ہیں۔
سندھ حکومت نے فیصلہ کیا اور اچھا فیصلہ کیا کہ سوائے سودا سلف کی دکانوں کے سب دھندے بند کیے جائیں تو پہلی دفعہ کیفے کلفٹن پر شٹر پڑے دیکھے اور ساتھ ہی یہ احساس ہوا کہ شہر میں ایک امیر کورونا ہے جو دبئی کے منرل واٹر کی تلاش میں ہے اور شہر میں ایک غریب کورونا ہے جو صبح ملنے والے مفت چائے پراٹھے سے محروم ہوگیا ہے۔

کراچی والے اپنے آپ کو بہت ہمت والے سمجھتے ہیں۔ میں کہتا رہا ہوں کہ ہم ڈھیٹ لوگ ہیں۔ الطاف حسین کی سقے شاہی ہو، رینجرز کے پے در پے آپریشن ہوں، ملک کے دوسری آفت زدہ علاقوں سے آنے والے پناہ گزینوں کا سیلاب ہو یا تابڑ توڑ ہونے والے دہشت گرد حملے، ہم دو دن بعد ہی کپڑے جھاڑ کر کھڑے ہو جاتے ہیں اور نکڑ والے پان کے کھوکھے پر کھڑے ہو کر پان لگواتے ہیں اور پوچھتے ہیں کہ ’اور سناؤ، کیا حال ہے؟‘
ہم اس کو ڈھٹائی کہہ لیں، بہادری کہہ لیں لیکن حقیقت یہ ہے کہ زیادہ تر شہر میں سکت ہی نہیں ہے کہ وہ کسی خوف اور صدمے کی وجہ سے گھر میں بند ہو کر بیٹھ جائیں۔

شہر کی آدھی سے زیادہ آبادی دیہاڑی دار ہے۔ روز کنواں کھودتے ہیں، روز پانی پیتے ہیں۔ گھر میں چار پانچ دن سے زیادہ کا راشن نہیں ہوتا۔ جب الطاف حسین کے دبدبے میں پورا کراچی آدھے گھنٹے کے اندر اندر بند ہو جاتا تھا تو 48 گھنٹے کے بعد لوگ ’بھائی گیا بھاڑ میں‘ کہتے ہوئے آہستہ آہستہ اپنے دھندوں کے لیے نکل پڑتے تھے۔

لیکن اب وہ ان دھندوں کے لیے جائیں بھی تو کہاں؟ ہر غریب امیر سکول کے باہر ایک بھنی ہوئی مکئی بیچنے والا یا ٹافیوں کی چھابڑی والا۔ سکول بند تو دھندا بند۔

ہر چھوٹے بازار کے کونے پر ایک موچی جو بابوؤں کے جوتے پالش کر کے اور مزدوروں کی چپلیں گانٹھ کر کے حلال رزق بنانے والا، بازار بند تو اس کا روزگار بھی بند۔

ساحلِ سمندر پر تھرماس سے قہوہ بیچنے والے، کرارے پاپڑ والے، اونٹوں اور گھوڑوں پر سواری کرانے والے۔ ساحلِ سمندر بند تو گھر کا چولہا بھی بند۔
سڑک کے کنارے ہتھوڑی، چھینی، ڈرل مشین، پینٹ برش لے کر آجر کا انتظار کرتے مزدور، وہ کھائیں یا کورونا سے بچیں؟

ٹریفک لائٹ پر غبارے، کھلونے بیچتے بچے اور 10 روپے کے عوض آپ کو حاجی صاحب کہنے والی بوڑھی عورت، شہر کے لاک ڈاؤن کے بعد یہ سب لوگ کہاں جائیں گے؟

سندھ حکومت کے مخالف بھی اور وہ لوگ بھی جو بھٹو کے نام کے ساتھ گالی دینا اپنا سیاسی فرض سمجھتے ہیں اس بات کے معترف ہیں کہ سندھ حکومت نے باقی صوبوں کے مقابلے میں بہتر کارکردگی دکھائی ہے۔ سکول، کالج، بازار بند کر کے لوگوں کو اس وبا سے بچنے کے لیے تیار کیا ہے۔

اب کیا ہی اچھا ہو کہ شہر میں پھیلے رفاہی اداروں کے جال جیسے ایدھی، سیلانی، امن فاؤنڈیشن اور اس جیسے بہت سے دوسرے اداروں کے ساتھ میں کر ان محنت کشوں کے لیے راشن اور دوسری ضروریاتِ زندگی کا بندوبست کیا جائے ورنہ صاحبِ حیثیت تو گھروں میں بند ہو کر اپنا منرل واٹر پیتے رہیں گے، لیکن مزدور اپنی جان ہتھیلی پر رکھ کر رزق کی تلاش میں نکلنے پر مجبور ہوگا۔
