Marburg virus was shown to survive for up to 4-5 days on contaminated
surfaces. In aerosol it was not stable, the specific rate of its inact
ivation being 0.05 min-1. This brought the authors to a conclusion tha
t a relatively close contact is needed for virus transmission from man
to man, although the possibility of aerosol transmission of the infec
tion may be appreciably increased in case of the hemorrhagic syndrome
with a high level of viremia.
