In a recent announcement, the CDC specifically recommended vaccinations for travelers given the highly contagious nature of measles, a serious respiratory illness.

The CDC emphasized that travelers are at risk of contracting measles in various environments, such as airports, train stations, public transportation, tourist sites, and large gatherings. CBS News reported that the CDC has already received 62 reports of travelers infected with measles either while flying into the U.S. or traveling domestically this year.

Measles spreads through coughing and sneezing, with the virus capable of surviving up to two hours in the air or on surfaces after an infected individual has vacated the area, according to the CDC. This means an infected traveler can bring the disease back to their home community, where it can quickly spread among unvaccinated people.

Most measles cases brought into the U.S. involve unvaccinated residents who get exposed to the virus during international trips. To prevent this, the CDC advises all international travelers to receive the measles-mumps-rubella (MMR) vaccine at least two weeks prior to their departure. This includes an early dose for infants aged 6 to 11 months and two doses, separated by at least 28 days, for anyone 12 months or older without proof of immunity.

For travelers uncertain about their measles immunity, the CDC recommends consulting a doctor at least six weeks before traveling to ensure there's sufficient time for vaccination. Those unable to get vaccinated safely should consider postponing their travel plans.

Measles can lead to severe health complications, regardless of age, such as pneumonia, encephalitis, and even death. Initial symptoms often include a rash, high fever, cough, runny nose, and red or watery eyes. The CDC advises people seeking medical care for measles symptoms to notify the facility in advance to prevent spreading the infection.
