A warning has been issued to Americans regarding travel to 31 countries due to an increase in polio cases.
The US Centers for Disease Control (CDC) has raised a level two alert, urging individuals to ensure their polio vaccinations are up to date. Those planning trips to the mentioned countries, such as the United Kingdom and Spain, are eligible for a one-time booster dose of the vaccine.
Polio, also known as poliomyelitis, was a major concern in the 20th century, but instances declined after the introduction of polio vaccines in the 1950s.
However, there has been a recent spike in cases in Europe and other regions. The CDC has identified several countries in its alert, including Finland, Germany, and Poland in Europe.
Individuals in the US planning to visit these nations are advised to receive the single-dose booster of the polio vaccine. This measure helps in preventing the spread of polio, a highly contagious virus that causes paralysis and can be fatal, affecting the nervous system. The virus is present in the feces of infected individuals and can be transmitted through contaminated food or water.
Most individuals infected with polio do not show symptoms, but those who do may experience flu-like symptoms, fatigue, nausea, headaches, nasal congestion, and a sore throat. In severe cases, polio can lead to paralysis, as seen in US President Franklin Delano Roosevelt, who required a wheelchair after contracting the disease.
The CDC states that “vaccination has eradicated wild poliovirus in the United States” through a series of four doses administered during childhood. In the UK, the polio vaccine is part of the routine childhood vaccination schedule provided by the NHS. Children receive six doses to achieve full immunity against polio, given at different ages from eight weeks to 14 years. British citizens may require polio booster shots before traveling abroad if their last vaccination was more than a decade ago.
However, US citizens face revised regulations this week following the polio outbreak. Authorities emphasize rising vaccination hesitancy contributing to the resurgence of once nearly eradicated diseases.
The countries included in the CDC alert are 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.
