    Best Question:

    What should I know about measles, polio, and other diseases before traveling? 

    You’re not wrong to be a bit concerned about exposure to previously unthinkable diseases while doing routine travel. 

    Whereas before we only worried about polio if you were going to parts of Afghanistan and Pakistan, now it’s a real concern in places like the U.K. and Germany. Measles is a huge concern in the U.S., and there have been dozens of exposures in airports and other tourist destinations this year alone (think Disney, concerts, and travel plazas). Other previously rare diseases are making a comeback as vaccination rates decline: rubella, whooping cough, meningococcal meningitis, and more. 

    Your best and first defense before traveling is proper vaccination. Make sure you have your routine vaccinations up to date, especially MMR, polio, and Tdap. If you’re traveling somewhere far flung, check to see if additional coverage is needed -  like the Japanese encephalitis, yellow fever, or chikungunya vaccines or even malaria meds. 

    If you’re traveling with an infant, consider early measles vaccination. Normally, the first dose of the MMR vaccine is given at one year, but if your baby is 6 months or older, they can get an extra, early dose to protect them before travel. 

    If you or someone you’re with is unvaccinated or immunocompromised, wear a mask and do your best to avoid indoor crowds. Wash your hands early and often, with soap and water when you can find it, and hand sanitizer when you can’t. It really does make a difference in protecting you.

    Scientists estimate somewhere between 5-35% of people don’t get sick from the flu, despite being exposed to the virus that causes it. Now, researchers may have figured out why.
