John RossI was today years old when I learned that there may be a relationship between pollen counts and viral respiratory infections. Pollen impairs the immune response to viruses, and viruses may also be able to hitchhike deep into the airways on pollen grains. High pollen concentrations in March 2020 may have facilitated the spread of COVID during the first pandemic wave 🤧 
Dagnabbit, Pascaline! 💥@johnrossmd Good that this news is out! It was known they travel well in polluted air, this is interesting extra information. People stil don'[t realise the virus is everywhere, in the air too.
I think it's common sense to wear a mask. But more research should be done to develop a 'common mask': sustainable design, easy to wash, and safe. All those filters, replacements, et cetera make using masks more of a pain and are a big environmental problem.
