The Maryland Department of Health has reported 26 mumps cases in the state in 2026 as of February 19, including 19 confirmed and 7 probable cases, with most recent infections occurring among adults in the Baltimore metropolitan area.
Officials say the overall risk to the public remains low due to Maryland’s high vaccination rates and are working with local health departments to determine whether the cases are connected, though no single link has been identified so far.
Health officials continue to emphasize that the two-dose MMR vaccine is the most effective way to prevent mumps, measles, and rubella, and recommend that residents check their vaccination status with their health care providers. Mumps spreads through direct contact and respiratory droplets, has no specific treatment beyond symptom management, and can sometimes lead to serious complications, particularly in adults, though most patients recover fully.
