Key Points

The COVID-19 pandemic disrupted the seasonal pattern of bronchiolitis outbreaks between 2020 and 2022; the 2022–2023 season marks the resumption of RSV circulation during the usual seasonal period in Guadeloupe and, to a lesser extent, in Martinique, which has not been the case in Saint Martin and Saint Barthélemy (no seasonal outbreaks since the COVID-19 pandemic).

The impact of the 2022–2023 season in the Caribbean remains broadly comparable to previous seasons before the COVID-19 pandemic.
