High temperature (30 [degrees] C) blocks aerosol but not contact transmission
of influenza virus.
fact sheet [cited 2010 Nov 30].
We hypothesized that live vaccinia virus shed from the skin reaction could not be recovered in the natural environment, and as a result, constitutes a limited risk for contact transmission
Evidence from wild primates and humans shows that pathogens with direct contact transmission
are associated with high host specificity (1,3).
The patterns of spread of severe acute respiratory syndrome (SARS) suggest droplet and contact transmission
Droplet and contact transmission
are considered the most effective means of transmitting influenza A in hospitals, and the clinical importance of airborne transmission has not been fully elucidated (6).
Under these controlled circumstances, airborne transmission was about two thirds as likely as contact transmission
