The Centers for Disease Control and Prevention (CDC) has issued a new global travel health alert due to rising concerns about polio and other viruses. This is an important update for anyone planning to travel internationally.
Polio Risk Level Increased
The CDC now considers polio to be a “Level 2” health threat, which means travelers should take extra care when visiting certain countries. This warning is part of the CDC’s Daily news highlights for global health. The updated advisory lists several popular destinations where poliovirus is still spreading, including:
- Finland
- Germany
- Spain
- United Kingdom
- Kenya
If you are planning to visit any of these places, the CDC advises getting a polio vaccine booster—even if you’ve already had the full vaccine series in the past. This booster helps protect you for life.
Important Health Tip: Before traveling, check that your vaccinations are up to date.
What Is Polio and Why It’s Dangerous
Polio is a virus that mostly spreads through contaminated water or food. Many people who catch polio don’t feel sick at all. But some can get symptoms like:
- Fever
- Fatigue
- Headache
- Sore throat or cough
- Stiff neck and body pain
In rare cases, polio can cause permanent muscle damage or even paralysis. If breathing muscles are affected, it could be life-threatening. This is why the CDC is asking people to be very careful, especially in countries where the virus still exists.
CDC’s Advice for Travelers
To stay safe during international trips, the CDC offers the following simple safety tips:
- Wash your hands regularly with soap and water
- Drink clean, filtered water
- Avoid contaminated food
- Get your vaccines before travel
These small actions can greatly reduce your chance of getting sick abroad.
Chikungunya Virus Also on the Radar
In addition to polio, the CDC is watching other diseases closely. One such illness is the chikungunya virus, which is caused by mosquito bites. This virus is spreading in:
- Guangdong Province, China
- Bolivia
People infected with chikungunya often get fever and joint pain. Older adults, newborn babies, and people with health conditions like diabetes or heart problems are at higher risk of severe illness.
Travel Tip: Pregnant women are advised not to travel to these areas, especially if their due date is near. The virus could be passed on to the baby.
How to Protect Yourself from Mosquitoes
To stay safe from mosquito-borne viruses like chikungunya or dengue fever, the CDC recommends:
- Using insect repellent
- Wearing long sleeves and pants
- Staying in air-conditioned rooms or places with window screens
Currently, dengue is rated as a Level 1 risk, which means it’s still a concern but not as serious as polio or chikungunya.
The CDC has not issued any Level 3 (reconsider travel) or Level 4 (avoid all travel) warnings at this time. However, it’s still very important to check for updates before traveling and follow all health recommendations.
