Survival of Enveloped and Non-enveloped Viruses on Surfaces Compared with Other Micro-organisms and Impact of Suboptimal Disinfectant Exposure.

Survival of enveloped and non-enveloped viruses, bacteria, yeasts and mycobacteria dried on polyvinyl chloride test carriers was determined. Reovirus, a non-enveloped virus, persisted and had a RF of 2 after 30 days whereas E. faecalis had an RF of 4 over the same time period. The other test organisms (Sindbis virus, P. aeruginosa, Mycobacterium chelonae and Candida albicans) had variable survivals but none survived as long as 30 days. Glutaraldehyde and hydrogen peroxide were effective at recommended dilutions. Breakthrough survival was detected at 0.1% glutaraldehyde and 0.05% AHP for all organisms tested.
