Selection of parameters for thermal coronavirus inactivation – a data-based recommendation
Martin Heßling, Katharina Hoenes, Christian Lingenfelder
Abstract
Coronaviruses can already be inactivated at relatively low temperatures. For most samples, application times of approximately 32.5, 3.7, and 0.5 minutes will be sufficient at 60°C, 80°C, and 100°C, respectively, for a 5 log-reduction. For difficult conditions, the worst-case model provides significantly longer application times of 490, 55, and 8 minutes for the temperatures mentioned.
