I was thinking about this the other day as I followed someone who was vaping. Enormous clouds of vape were exiting his lungs and hanging in the air, so I crossed the road to prevent walking into it.

I assume that oily/moist vape clouds are quite good at hosting viral particles in them.

There's no reason to suppose your risk would be any lower than if they had not been vaping. When you go out, you could usefully imagine everyone around you is vaping and you're trying to avoid breathing in the visible exhalations. That should help you avoid the invisible, infectious exhalations.

In summary, our report suggests that SARS-CoV-2 infection leads to disrupted CD8+ T cytotoxic functions and changes the overall metabolic functions of immune cells.

I have no idea if the additional liquid droplets being exhaled could be an additional vector for viruses.

I think headshot is right about it "hanging in the air" - people do all kinds of crazy tricks with it, which I've not seen from similarly voluminous methods of producing smoke e.g. shisha or bongs.

I try to avoid joggers for the same reason, or at least breathe out/hold my breath in the seconds after they go by. Also, I won't be rejoining a local walking group for the foreseeable, same reason again.

The survey found myocarditis in close to 15 percent of athletes who had the virus, almost all of whom experienced mild or no symptoms, Daniels added, perhaps shedding more light on the uncertainties about the short- and long-term effects the virus may have on athletes.

Results: We recruited 286 adults with exposure to respiratory infections in the Australian winters of 2006 and 2007 - 94 adults were randomized to surgical masks, 90 to P2 masks and 102 to the control group. Using intention to treat analysis, we found no significant difference in the relative risk of respiratory illness in the mask groups compared to control group. However, compliance with mask use was less than 50%. In an adjusted analysis of compliant subjects, masks as a group had protective efficacy in excess of 80% against clinical influenza-like illness. The efficacy against proven viral infection and between P2 masks (57%) and surgical masks (33%) was non-significant.

Conclusions: This is the first RCT on mask use to be conducted and provides data to inform pandemic planning. We found compliance to be low, but compliance is affected by perception of risk. In a pandemic, we would expect compliance to improve. In compliant users, masks were highly efficacious. A larger study is required to enumerate the difference in efficacy (if any) between surgical and non-fit tested P2 masks.

I hoping this is because some kind of lab backlog, but it is a pretty significant leap.
