All measles cases in the United States originate from international travel. Your patients are at risk for measles infection if they have not been fully vaccinated. The best way to protect them from this serious disease — and prevent potential measles outbreaks in the US — is vaccination before travel.
In addition, if you see patients coming to the US from measles-endemic countries such as Afghanistan, Somalia, or the Democratic Republic of Congo, assess their vaccination history and offer recommended vaccines, including MMR for measles, mumps, and rubella, and IPV for polio.
