Best Question:
I’m traveling soon to Europe. What do I need to know about polio?
Recently, the CDC issued a Level 2 travel advisory warning Americans to take extra precautions against polio when traveling to 30 different countries - including relatively common European destinations like the U.K., Germany, and Poland. There are 27 other countries on the list, too, across Africa, South and Southeast Asia, and the Middle East.
If you have travel coming up, the most important thing you can do to protect yourself is to make sure you’re fully vaccinated against polio. The polio vaccine we use in the U.S. is inactivated, which means you have no risk of actually getting polio from the vaccine. It’s got decades of data proving it’s safe, and it offers strong long-term protection.
If you’ve already been fully vaccinated for polio, you generally only need a booster if you’re going to Afghanistan or Pakistan where wild-type polio is still endemic, or if you’re a healthcare worker working with polio samples directly. If you’re immunocompromised, chat with your doctor before traveling.
If you’re traveling with an infant or child that hasn’t been vaccinated yet, it may be a good idea to postpone travel, depending on where you’re headed. You should absolutely discuss with their pediatrician; some may offer early vaccination if appropriate.
In all, this isn’t something to panic over, but it’s a good idea to check your vaccination status before you travel. As global vaccination rates fall, your best protection is making sure that you and your family are protected.
20 people have been confirmed with group B meningitis, and 2 have died after a U.K. outbreak on a university campus that happened almost overnight. Some outlets report even more cases, though those have been walked forward and back again a few times by authorities. There are still lots of questions that remain.
