" “Unlike seasonal influenza or common colds where the transmission chains get easier to break in the warm, humid, summer months, especially amongst communities with herd immunity, we cannot count on COVID-19 relenting simply because of a change of season. There has to be a chain of human transmission to support the seasonality of a particular illness; so breaking that transmission is absolutely critical. If it finds enough of a foothold in enough places that we don’t detect, it will re-emerge in the fall.”
