Anyone have any info on the comparability of COVID-19 to H1N1 in terms of transmission methods since we have official trace data, studies and reports on H1N1? Am having this discussion and being pointed out the fact that H1N1's particulate size is actually smaller than COVID-19 (80-120nm vs 200nm respectively).
