Intra-Family and inter-family comparisons for viral susceptibility to heat inactivation

Abstract

A systematic review of the viral heat inactivation literature for data compatible with modeling using the decimal reduction value/z value approach as well as a new approach based on the power function relationship between decimal reduction value and inactivation temperature is presented. The review has enabled us to conduct quantitative intra-family and inter-family comparisons for various heat inactivation characteristics for viruses, including z value, temperature in°C for 1 log10 and for 4 log10 inactivation in 30 seconds. The parvoviridae family is confirmed to be the most heat resistant of the various virus families for which data were analyzed. © 2013 Nims RW, et al.
