Source of Milwaukee measles outbreak determined

According to a report by the Centers for Disease Control and Prevention, the recent measles alert in Milwaukee began when an unvaccinated 23-month-old refugee from Myanmar flew to the U.S. from Malaysia.
The child, who flew to Wisconsin on August 24, was reported to have laboratory confirmed measles on September 7. Since that time, measles have been confirmed in two more people in Milwaukee, both of whom seem to have acquired the disease through exposure to the refugee patient, the Milwaukee Journal Sentinel reports.
The CDC's"Morbidity and Mortality Weekly" also reported an unvaccinated Burmese refugee was confirmed with measles in California on August 26, flying to the U.S. on the same day as the Milwaukee refugee. While the patients in Wisconsin and California flew on different flights, three other unvaccinated refugee children who were on the same flight as the boy in California have also come down with confirmed measles cases. Two of them are very young children in Maryland and one is a 14-year-old in North Carolina.
"Whether these three patients were exposed to measles in Malaysia or during travel to the United States is unclear," the CDC report said, according to the Milwaukee Journal Sentinel.
To prevent further measles transmission, refugee travel from Malaysia to the U.S. has been suspended. Milwaukee health workers are working with refugee resettlement agencies as part of an outreach effort to control and identify the spread of measles. The report recommended that U.S.-bound refugees in Malaysia with no apparent immunity should be vaccinated for measles, mumps and rubella and have their travel to the U.S. postponed for 21 days after vaccination.
