ANALYSIS: Will coronavirus really evolve to become less deadly? This article first appeared on The Conversation. A recent modelling study painted a reassuring picture of a post-pandemic future in which SARS-CoV-2 transitions, over “a few years to a few decades”, from dangerous pathogen to just another common-cold coronavirus. This predicted loss of virulence, the authors stress, is based on a specific idiosyncrasy of the virus, namely that it rarely causes serious disease in children. Still, many experts agreed that we should not be in the least surprised by the authors’ conclusion, as all viruses “become more transmissible and less pathogenic over time”. After all, the seductive logic goes, from an evolutionary perspective it makes no sense for a pathogen to harm the host on which it depends for its survival. According to this reasoning, virulence is little more than a temporary evolutionary imbalance.
