AbstractSARS-CoV-2 causes an acute respiratory tract infection that resolves in most people in less than a month. Yet some people with severely weakened immune systems fail to clear the virus, leading to persistent infections with high viral titres in the respiratory tract. In a subset of cases, persistent SARS-CoV-2 replication results in an accelerated accumulation of adaptive mutations that confer escape from neutralizing antibodies and enhance cellular infection.
