CDC is aware of probable measles cases being reported by jurisdictions. However, the data on this page only includes confirmed cases jurisdictions have notified to CDC.
The CDC reports the cumulative number of measles outbreaks (defined as three or more related cases) that have occurred this year in the U.S.; states have the most up-to-date information about cases and outbreaks in their jurisdictions.
The CDC said the best way to protect against measles is to get the measles, mumps and rubella (MMR) vaccine. Children may get the measles, mumps, rubella and varicella (MMRV) vaccine instead, which protects against chickenpox, too.
Most people who are vaccinated with MMR or MMRV will be protected for life. Vaccines and high rates of vaccination have made these diseases much less common in the United States.
