Polio in Asia
COVID-19 is spreading worldwide. CDC recommends you avoid all nonessential international travel. If you must travel, follow the recommendations in the Global COVID-19 Pandemic Notice, in addition to any travel health recommendations provided in this notice.
- There are polio outbreaks in several countries in Asia.
- CDC recommends that all travelers to these countries be vaccinated fully against polio.
- Before traveling to these countries, adults who completed their routine polio vaccine series as children should receive a single, lifetime adult booster dose of polio vaccine.
Polio is a crippling and potentially deadly disease that affects the nervous system. Good hand washing practices can help prevent the spread of this disease. Because the virus lives in the feces (poop) of an infected person, people infected with the disease can spread it to others when they do not wash their hands well after defecating (pooping). People can also be infected if they drink water or eat food contaminated with infected feces.
Most people with polio do not feel sick. Some people have only minor symptoms, such as fever, tiredness, nausea, headache, nasal congestion, sore throat, cough, stiffness in the neck and back, and pain in the arms and legs. In rare cases, polio infection causes permanent loss of muscle function (paralysis). Polio can be fatal if the muscles used for breathing are paralyzed or if there is an infection of the brain.
What is the current situation?
Polio outbreaks have been reported in the following Asian countries (map):
- Burma (Myanmar)
- Papua New Guinea
- The Philippines
The World Health Organization recommends that these countries require residents and long-term (4 weeks or more) visitors show proof of polio vaccination before leaving the country (See: WHO Statement of the Twenty-Second IHR Emergency Committee Regarding the International Spread of Poliovirus).
What can travelers do to prevent polio?
Get the polio vaccine. CDC recommends that all travelers to the countries listed above be vaccinated fully against polio. Adults who were fully vaccinated during childhood should receive an additional (single) lifetime booster dose of polio vaccine. Even if you were vaccinated as a child or have been sick with polio before, you may need a booster dose to make sure you are protected. See the Polio Vaccine Information Statement (VIS) for more information.
For travelers going to countries with circulating poliovirus who have completed their routine polio vaccine series but who have not already received an adult booster dose, CDC recommends administering an inactivated poliovirus vaccine (IPV) booster dose.
See the Vaccine section in Chapter 4, Poliomyelitis, CDC Yellow Book, for specific vaccination details.
