Yes, at recent mtg. I attended on COVID-19, there are 2 strains, S-type and L-type, S-type being more contagious and less virulent, L-type the more virulent strain (if I remember correctly). Prevailing theory is that the more contagious less virulent strain will out-compete the other strain and nat. selection with eventually eliminate the more virulent strain. We are still preparing for max capacity and overflow scenarios either way.
