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

Key Points

Seventy percent of measles patients were exposed to the virus in healthcare facilities, highlighting a significant nosocomial transmission component.
Of the 287 cases investigated, 75% were unvaccinated with 130 patients under the age of five, showing the vulnerability of young children.
The outbreak involved three transmission chains, which collectively accounted for 183 cases, illustrating the scale of the issue during March-July 2023.

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.
