Changes in the Epidemiology of Influenza and Respiratory Syncytial Virus During 2020–2022 Relative to the Pre‐COVID‐19 Pandemic Period (2017–2020) From Systematic Sentinel Syndromic Surveillance in South Africa

We report low levels of influenza circulation and out-of-season RSV circulation in 2020 with changes in the age distribution of cases and risk of ICU admission. Return to prepandemic timing was earlier for RSV, with higher seasonal peaks for influenza-associated ILI and RSV-associated SRI in 2022.
