Not airborne????????????????????
What recent study tells you that..because there are plenty of studies that say the opposite.
Btw, negative pressure rooms are recommended for COVID 19 patients
Medcram Dr is running out of them and puts two COVID patients to a negative pressure room.
btw, WHO says it is NOT airborne...no one should trust them
