In hamsters, co-exposure to crocidolite and one strain of SV40 virus had the effect of amplifying the risk of mesothelioma from asbestos. SV40 has not been conclusively shown to be a cause of mesothelioma in humans, and in our view, is unlikely to be.
Evidence from:
B Kroczynska et al. PNAS (2006) Vol.103#38 p 14128 – 14133
“Crocidolite asbestos and SV40 are cocarcinogens in human mesothelial cells and in causing mesothelioma in hamsters”
The joint potency of virus and asbestos was higher in hamsters. Given joint and several liability for asbestos exposure it seems unlikely anyone would bring SV40 into play.
