Measles cases rise sharply nationwide, including in DC area in 2026

The United States is experiencing a significant increase in measles cases in 2026, with the Centers for Disease Control and Prevention (CDC) reporting 4,588 confirmed cases nationwide as of October 22, 2026. This number more than doubles the total cases reported in 2025, according to FOX 5 DC.

The CDC data shows that 96% of these cases are associated with outbreaks, with 43 new outbreaks reported this year. Cases have been confirmed in 47 states, including the Washington DC area, which is part of the broader national trend.

Measles is a highly contagious virus that can linger in the air for up to two hours. The CDC notes that about nine out of ten people who are not immune will contract the virus if exposed. Before the introduction of the vaccine in 1963, measles caused millions of cases annually in the US.

Vaccination remains the most effective way to prevent measles. The CDC recommends the measles, mumps, and rubella (MMR) vaccine, especially for those planning to travel. The virus was considered eliminated in the US since 2000 but has seen resurgence due to declining vaccination rates in some areas.

Local residents are advised to consult healthcare providers about vaccination to protect themselves and their communities from the spread of measles.
