Atypical measles occurs in people who received the killed measles vaccine (KMV; only used from 1963 until 1967) and who are exposed to wild-type measles virus. The KMV unfortunately sensitizes the patient to the measles virus but does not offer any protection. The disease is characterized by fever, pleural effusions, pneumonia, and swelling of the extremities. The rash of atypical measles is different from measles in that it may have an urticarial component (hives) and usually appears first on the ankles and wrists.
It is recommended by the U.S. Centers for Disease Control and Prevention (CDC) that people who may have received the KMV should receive revaccination with the live measles vaccine.
The virus can be isolated in tissue culture in the lab. Blood (serologic) tests are also available.
