The Centers for Disease Control and Prevention (CDC) has issued a travel advisory urging Americans to take precautions against polio as the virus continues to spread in multiple regions around the world. The agency has established a Level 2 alert, indicating travelers should “practice enhanced precautions” when visiting affected countries.
The CDC recommends individuals verify they are up-to-date on their polio vaccination. For those planning travel to any of the 32 countries on the list, a single booster dose before departure is too advised. This advisory highlights the importance of maintaining global vaccination efforts to prevent the resurgence of preventable diseases.

The list of countries where polio transmission has been detected includes Afghanistan, Algeria, Angola, Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Côte d’Ivoire, Democratic Republic of the Congo, Djibouti, Ethiopia, Finland, Gaza, Germany, Ghana, Guinea, Israel, Niger, Nigeria, Pakistan, Papua New Guinea, Poland, Senegal, Somalia, South Sudan, Spain, Sudan, Tanzania, United Kingdom, Yemen, and Zimbabwe.
Polio is caused by the highly contagious poliovirus and, according to the CDC, is “a debilitating and potentially fatal disease that affects the nervous system.” The virus is found in the stool of infected individuals and can spread through contaminated food or water.
Most people infected with poliovirus do not experience symptoms. When symptoms do occur, they are typically flu-like, including fever, fatigue, nausea, headache, nasal congestion, and sore throat. In severe cases, the disease can lead to paralysis, as famously experienced by former U.S. President Franklin D. Roosevelt.

The CDC emphasizes that “vaccination has helped to eliminate wild poliovirus in the United States.” The vaccination schedule involves four doses administered during childhood. However, health authorities caution that increasing vaccine hesitancy is contributing to the resurgence of diseases that were once nearly eradicated.
The debate surrounding vaccination continues, with some experts questioning mandatory policies. Pediatric cardiologist Kirk Milhoan, who chairs the Advisory Committee on Immunization Practices, has argued that vaccines against polio and other diseases should be optional. “If there is no choice, then informed consent is an illusion,” he told the New York Times. “Without consent It’s medical assault.”
