The Centers for Disease Control and Prevention has issued a level 2 travel advisory warning of poliovirus detections in more than 30 destinations across Africa, the Middle East, and Europe. Travelers are urged to ensure their polio vaccinations are up to date before international trips. The advisory, released on March 3, highlights the risks associated with the disease's resurgence in these areas.
The Centers for Disease Control and Prevention (CDC) announced a level 2 travel advisory on March 3, cautioning international travelers about poliovirus circulating in various countries over the past 12 months. This measure follows detections in parts of Africa, the Middle East, and Europe, where the virus has resurfaced despite global vaccination efforts.
The advisory lists over 30 affected countries, including Afghanistan, Algeria, Angola, Benin, Burkina Faso, Cameroon, Central African Republic, Côte d'Ivoire, Democratic Republic of the Congo, Djibouti, Ethiopia, Finland, Germany, Ghana, Guinea, Israel, Niger, Nigeria, Pakistan, Papua New Guinea, Poland, Senegal, Somalia, South Sudan, Spain, Sudan, Tanzania, United Kingdom, Yemen, and Zimbabwe. Polio, a highly infectious disease that invades the nervous system, can cause irreversible paralysis or death in rare cases, particularly if it affects breathing muscles. Most infections show no symptoms, but some individuals may experience fever, fatigue, nausea, headache, or muscle stiffness.
Transmission occurs mainly through contact with contaminated food or water, exacerbated by poor hand hygiene, as the virus is present in the feces of infected people. The CDC emphasizes that vaccination is the primary defense. Routine polio vaccines are recommended for children and adults planning international travel. Those who have completed the series may need a single lifetime booster if visiting areas with active circulation. Unvaccinated travelers or those with incomplete series should complete immunization before departure.
In the United States, polio remains rare due to high vaccination rates, but international travel heightens exposure risks during outbreaks abroad. The agency advises consulting healthcare providers to verify vaccination status ahead of trips to these destinations.
