CDC Issues New Warning Over Fatal Disease’s Spread: What To Know In CA

Federal health officials are warning tourists from California and from across the country that global travel carries an increased risk for polio, which is circulating in about 30 countries.

Polio vaccines are universally required for public and private school students, including in California; however, policies allow for medical exemptions and, in many states, religious or personal belief exemptions.

What about this: In California, vaccination requirements differ by age for children in preschools, day care centers or early childhood learning centers . Those under 1 year old need one dose, while three doses are generally required for children 18 months or older, according to the California Department of Public Health.

Students in K-12 schools are required to have three or more doses, with a fourth dose mandatory if administered on or after the child's fourth birthday.

The Centers for Disease Control and Prevention’s advisory is a Level 2 warning that encourages travelers to “practice enhanced precautions,” especially in the following destinations:

• 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
• Zimbabwe

Polio, a highly contagious, crippling and potentially deadly disease primarily affecting children under 5, can invade the nervous system and cause paralysis. According to the World Health Organization, it is usually spread through fecal matter, contaminated water or food, or failure to wash hands after using the bathroom.

The CDC says 95 percent of people infected with polio show no symptoms, and that when symptoms do occur, they often mimic the flu, including fever, fatigue, headache, vomiting, and neck stiffness. Symptoms last two to 10 days, and most people fully recover.

Fewer than 1 percent of cases are severe illnesses that can cause paralysis, often in the legs, or be fatal if it infects the brain or paralyzes the breathing muscles.

There is no known cure for polio, but it can be prevented by vaccinations. The CDC is advising people who travel to any of the named countries to make sure they’re up-to-date on polio vaccines.

Most adults born in the United States can assume they are vaccinated, according to the CDC. Adult travelers may get a booster if they are going to a destination that has circulating poliovirus; have completed their routine polio vaccine series; and have not already received one adult booster dose.
