Covid-19 can remain in air for hours, warns Thai respiratory doctor

Latest tests show that the Covid-19 virus can spread via airborne transmission, Dr Manoon Leechawengwongs, a respiratory specialist at Bangkok’s Vichaiyut Hospital, said today (July 24).

 

He said scientists now believe the virus can spread in airborne droplets smaller than 5 microns when patients exhale, speak, cough or sneeze. The droplets can spread more than 2 metres and remain in the air for several hours.

 

"Recently, US scientists at the University of Nebraska took an air sample from a Covid-19 patients’ room to cultivate in a Vero-E6 cell culture and found that the number of Covid-19 viruses increased," he explained on Facebook. "The test showed that Covid-19 virus can spread through airborne transmission."

 

He said that the World Health Organisation and government agencies worldwide now recognised the airborne spread of this disease and were advising people to wear face masks.

 

"Currently, we can conclude that Covid-19 can spread through aerosol, droplets, and by touching contaminated surfaces," he said.

 

He added that wearing a face mask is the best way to prevent the spread of Covid-19 because it has been shown to cut chances of transmission by up to 75 per cent.

 

"Also, people should maintain distance with others and wash their hands regularly," he added.

This is not new. Been known for some time.

Tis true, tis true. 

 

A new study, published in the medRxiv depository, now suggests that the novel coronavirus COVID-19 could remain in the air up to 3 hours post aerosolization.

Surely there aren't many droplets remaining in the air, now that Thailand claims to have had 60 virus free days, with the exception of those in quarantine after returning here ?

I thought its always in the air 555

I want to see a report that smoke particles, from burning your rubbish in the garden, can pick up the Covid virus from the air and transport it very long distances.

????????

the perfect  bio weapon

This is not news just someone wanting their minute of media exposure again.

From the same report

"On a broader scale the scientists have not reached consensus whether COVID-19 should be called airborne or whether it is transmittable only from droplets. Airborne or not, when the water component of droplets dries up in the air, the remaining bits of floating virus are called “droplet nuclei,” which are lighter and able to travel long distances."

 

UV from the sun kills it directly, so go out, but in many countries, people are forced to stay inside, avoid the beaches, etc...  very humid air (+ UV sun) is probably why Thailand was "saved".

 

Closing malls & other places where air is circulated, with cold DRY air might also have been a good idea

Again and again the risk for airborne is in crowded , poorly ventilated environments, with prolonged exposures. I would not worry about passing an infected person in a mall.   But : https://www.nydailynews.com/coronavirus/ny-coronavirus-florida-lynchs-bar-closed-15-people-infected-one-night-20200616-yvsmo4ysy5dczlpmtsv74ywqce-story.html

This knowledge has been published long time ago, domestically it's much more interesting to know if they can remain airborne for 60 days...????

Hard-line, and some not so hard-line, governments world-wide enjoying every minute of the covid 19 panic. It assures them of total control into the foreseeable future. 

Cosmic rays will kill in impact depending on circumstances. Who is this dude?

They have got to keep the fear going thou. What else is there to report

Only at night.

Yeah, so long as the droplet remains completely uncompromised, it can survive. These are results achieved in a laboratory environment, which is far from real world conditions. Obviously adding that information to "informative" articles, won't yield nearly as much click revenue. Nonetheless, it's no where near as lethal as they convinced people it was in the beginning. If this guy really wants attention, he should just say that som tam can house the virus easier than any other dish available. 

This is fake news. Where's Auntin

His pens been busy. <deleted>

And so, why are people being forced and encouraged to stay indoors all over the world? 

 

It is utter lunacy. Is it too much to ask that our findings actually line up with policy decisions. Why would parks be closed for example?

Then eyes could be an entry point as well.

You'd really need to look into the probabilty of getting infected by aerosolized virus, virus density in air vs. probability of an infection that will cause COVID. I think it's miniscule, especially when wearing a mask, unless a lot of people cram into a small space and start shouting or singing, such as a pub or a church.

Well this is information that may provide the reasons why some crowds at

beaches and parties have spread this virus so well. However the anti- maskers

will say,  not true..  Picture of these anti maskers included.
