Although the virus is not usually airborne, the National Academy of Sciences has suggested that bioaerosol transmission may be possible and that air collectors positioned in the hallway outside patient rooms have produces samples positive for viral RNA.
Ingawa kwa kawaida virusi hivyo haviwezi kusambazwa hewani, Chuo cha Kitaifa cha Sayansi kimependekeza kuwa inawezekena kuambukiza kupitia chembechembe za hewa na vikusanya hewa vilivyo katika njia nje ya vyumba vya watu vilikuwa na sampuli chanya za virusi vya RNA.
