It's unfortunate that you don't have the source, because it would be nice to see how long after after the covid-19 patient left the chamber they tested the air for the virus.
People need to understand that there is a good possibility that this virus can stay in the air, even if it is only for 5 or 10 minutes. If using the word airborne isn't correct use of scientific jargon, it at least is correct use of common English.
- DennisP 7y agoThe article mentions another test that measured three hours in the air, though they say it's probably no more than half an hour in real-world conditions.
- jacobolus 7y agoThat’s a lab test where they first aerosolize the virus and then spray it into the air and measure how long it lasts. It doesn’t necessarily reflect what actually happens when someone breathes or coughs.
- James_Henry 7y agoYes, the researchers thought that in normal instances that it could last 30 minutes in the air. Also, health officials are pointing to instances like this choir practice to show that aerosolization of the virus is an important thing to take into consideration.
- beerandt 7y agoIf it's the same test I saw, it was at least 3 hours in the air; they stopped sampling at that point, as they were mostly measuring different surface persistence.
