Ongoing measles outbreaks in Romania, March 2023 to August 2023

Abstract

Measles cases have recently been increasing in Romania, with 460 confirmed cases by August 2023. From March 2023, measles cases increased, and outbreaks were recorded in Cluj, Bistrita Nasaud, Sibiu and Mures counties. New D8 virus variants were identified, different from the variants detected in Romania before the COVID-19 pandemic. We here provide epidemiological and molecular data on the current increase in measles cases in the context of the measles elimination process in the World Health Organization European Region.
