Omicron variant increases risk of SARS-CoV-2 reinfection

New surveillance data from South Africa published in the medRxiv* preprint server suggests that the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omnicron variant has the potential to escape naturally-acquired immunity. The research indicates people who previously recovered from a coronavirus disease 2019 (COVID-19) are at risk for reinfection with the Omicron variant. The results show that the risk of reinfection is greater with the Omicron variant versus Delta and Beta.
