In a recent Correspondence by Durrheim et al., the authors described the looming threat of measles amid the COVID-19 pandemic1. We agree with the concerns raised by the authors, as shown by the alarming measles outbreak now ongoing in Pakistan, concurrent with the COVID-19 pandemic. Measles is one of the most contagious viral diseases and is a leading cause of morbidity and mortality, with around 2.6 million annual deaths worldwide. The basic reproduction number of 12 to 18 for the measles virus is the highest of any respiratory virus, and is much higher than that of the coronavirus SARS-CoV-2, the cause of COVID-191.
