RNA viruses have extremely high mutation rates, which are crucial for the ability of these viruses to adapt but can also lead to population extinction. Here, Andino and colleagues describe the mechanisms that RNA viruses use to cope with the high mutational load and discuss the impact of mutational robustness on population dynamics, pathogenicity and antiviral therapies.
