Measles Outbreak Driven by Nosocomial Transmission, Armenia, February–July 2023

During March-July 2023, we investigated a measles outbreak in Armenia. Of 287 patients, 130 were <5 years of age and 215 (75%) were unvaccinated. Among 3 transmission chains involving 183 cases, 70% of patients were exposed in healthcare facilities. To minimize nosocomial transmission, measles vaccination should be encouraged among healthcare workers.

Abstract

During March-July 2023, we investigated a measles outbreak in Armenia. Of 287 patients, 130 were <5 years of age and 215 (75%) were unvaccinated. Among 3 transmission chains involving 183 cases, 70% of patients were exposed in healthcare facilities. To minimize nosocomial transmission, measles vaccination should be encouraged among healthcare workers.
