Abstract
Exposure of a virulent isolate of Newcastle disease virus (NDV) and two highly pathogenic avian influenza (HPAI) viruses, one of H7N1 subtype and the other H5N1 subtype, to a continuous ultraviolet B flux of approximately 90µW/cm(2), which models solar ultraviolet radiation, resulted in an exponential decline in infectivity with time. The time taken for a reduction in titre of 1 log10 median tissue culture infectious dose for each virus was: NDV, 69 min; H7N1 HPAI virus, 158 min; and H5N1 HPAI, virus 167 min.
