it is not AIR

FOG or smoke lo it can survive but not in air.

 

Federally funded tests conducted by scientists from several major institutions indicated that the novel form of coronavirus behind a worldwide outbreak can survive in the air for several hours.

A study awaiting peer review from scientists at Princeton University, the University of California-Los Angeles and the National Institutes of Health (NIH) posted online Wednesday indicated that the COVID-19 virus could remain viable in the air "up to 3 hours post aerosolization," while remaining alive on plastic and other surfaces for up to three days.

"Our results indicate that aerosol and fomite transmission of HCoV-19 is plausible, as the virus can remain viable in aerosols for multiple hours and on surfaces up to days," reads the study's abstract.

The test results suggest that humans could be infected by the disease simply carried through the air or on a solid surface, even if direct contact with an infected person does not occur. That finding, if accepted, would come in stark contrast to previous media reports that suggested the virus was not easily transmittable outside of direct human contact.

AIR borne is very dangerous...oka sari adi hit aindi ante kashtam..

anduke temperature enta pergite anta better....

 

don't think so it propagates by Air, else why would they say keep few feet distance...

Evaru chepparu it wont propagate by air ani ? 
covid will propagate through air thats why it is more dangerous like Other family virus

It propagates by air as well for shorter time, not sure if it will stay virulent.

They said it's viable, not sure if the virulence is the same. Will be good to check it.

once it is in Air...virulance probability increases if people keep moving..

lockdown can curtail it still..but still chances of getting infected more if weather is humid..like for this enitre week in Bay Area...

It can survive possibly around 2-3 hrs in Air but cannot travel much thats why they are telling keep distance even if some one sneezes so that those droplets won't fall on you..

I remember some one may be from ICMR mentioned it doesn't propagate much by air today evening i didn't go throught the article fully let me find it out if i can..

Points from some other soruce  https://www.health.harvard.edu/diseases-and-conditions/coronavirus-resource-center

 

How long can the coronavirus stay airborne? I have read different estimates.

A study done by National Institute of Allergy and Infectious Diseases' Laboratory of Virology in the Division of Intramural Research in Hamilton, Montana helps to answer this question. The researchers used a nebulizer to blow coronaviruses into the air. They found that infectious viruses could remain in the air for up to three hours. The results of the study were published in the New England Journal of Medicine on March 17, 2020.

How long can the coronavirus that causes COVID-19 survive on surfaces?

A recent study found that the COVID-19 coronavirus can survive up to four hours on copper, up to 24 hours on cardboard, and up to two to three days on plastic and stainless steel. The researchers also found that this virus can hang out as droplets in the air for up to three hours before they fall. But most often they will fall more quickly.

There's a lot we still don't know, such as how different conditions, such as exposure to sunlight, heat, or cold, can affect these survival times.

As we learn more, continue to follow the CDC's recommendations for cleaning frequently touched surfaces and objects every day. These include counters, tabletops, doorknobs, bathroom fixtures, toilets, phones, keyboards, tablets, and bedside tables.

If surfaces are dirty, first clean them using a detergent and water, then disinfect them. A list of products suitable for use against COVID-19 is available here. This list has been pre-approved by the U.S. Environmental Protection Agency (EPA) for use during the COVID-19 outbreak.

In addition, wash your hands for 20 seconds with soap and water after bringing in packages, or after trips to the grocery store or other places where you may have come into contact with infected surfaces.

WHO South-East Asia office says COVID-19 not airbone virus

A statement by the WHO's South-East Asia regional office said, “Airborne spread has not been reported for COVID-19.  Based on the information received so far and on our experience with other coronaviruses, COVID-19 appears to spread mostly through respiratory droplets (for instance produced when a sick person coughs) and close contact. This is why WHO recommends maintaining hand and respiratory hygiene.
 
"The Chinese authorities reported that there could be a possibility of aerosol transmission in a relatively closed environment with prolonged exposure to high concentrations of aerosols, like in ICUs and CCUs in hospitals, but more investigations and analysis of epidemiological data is needed to understand this mode of transmission of the virus.

covid sars mers all are same family virus

MERS is contagious (infectious) from person to person by respiratory droplets, either by breathing airborne droplets, or contact of respiratory secretions with moist membranes of the mouth, nose, and eyes. It is contagious from camel to human via respiratory droplets as well as meat, milk, and urine of an infected animal, even though the animal may not appear sick.
