I'll take this one, if you don't mind.
What we know is that, in certain circumstances, particularly when you're in a hospital and you do medical procedures, you might be able to aerosolize that virus. For instance, if you intubate a patient, if a patient is on CPAP, when you go in the airways, we know that it aerosolizes the virus. That's why we put them in negative pressure rooms. We wear N95 masks and all the rest.
What is still not completely clear is what happens when a person coughs or does physical activity and breathes out very strongly. I think that what seems to happen is that you are able to have smaller droplets that will be suspended in the air for five to eight minutes, but it's not per se for now in aerosol.
Studies are currently ongoing, particularly in long-term care facilities where we're all wondering if airborne transmission is not happening, given the proportion of people who become infected when they just go into those facilities. Air sampling is being done with cultures of air. We know that we are able to find pieces of viruses in the air in long-term care facilities, but we don't know if that's a piece of a virus that's dead or if it's a virus that's still able to replicate.
The studies are ongoing right now, and I think we'll have the results within the next month or so. At that point in time, we'll know. At this point in time, I think daily living will cause droplets that may be suspended in the air for five to eight minutes, like when you sing, for instance, and when you cough very hard, and that is still able to infect the next person. Aerosolization per se for now is not yet approved upon.... The jury is still out, as Dr. Tremblay would say.
