Sensitivity to ultraviolet radiation of Lassa, vaccinia, and Ebola viruses dried on surfaces.
Abstract
Germicidal UV (also known as UVC)
provides a means to decontaminate infected environments as well as a
measure of viral sensitivity to sunlight. The present study determined UVC
inactivation slopes (and derived D(37) values) of viruses dried onto
nonporous (glass) surfaces. The data obtained indicate that the UV
resistance of Lassa virus is higher than that of Ebola
virus. The UV sensitivity of vaccinia virus (a surrogate for variola
virus) appeared intermediate between that of the two virulent viruses
studied. In addition, the three viruses dried on surfaces showed a
relatively small but significant population of virions (from 3 to 10 %
of virus in the inoculum) that appeared substantially more protected by
their environment from the effect of UV than the majority of virions
tested. The findings reported in this study should assist in estimating
the threat posed by the persistence of virus in environments
contaminated during epidemics or after an accidental or intentional
release.
