Threat Assessment Brief: Reinfection with SARS-CoV-2: considerations for public health response

Summary:

Cases with suspected or possible reinfection with SARS-CoV-2 have been recently reported in different countries. In many of these cases, it is uncertain if the individual’s Polymerase Chain Reaction (PCR) test remained positive for a long period of time following the first episode of infection or whether it represents a true reinfection. The aim of this Threat Assessment Brief is to elucidate the characteristics and frequency of confirmed SARS-CoV-2 reinfection in the literature and to summarise the findings about SARS-CoV-2 infection and antibody development.
