Recommended Vaccinations: Polio

Due to the risk of Polio virus transmission in Myanmar | Burma, all residents and long-term visitors (4 weeks or more) coming from Polio-affected countries should be prepared to present a valid International Vaccination Certificate proving they were vaccinated with Oral Polio Vaccine or Inactivated Polio Vaccine between 4 weeks and 12 months prior to entry. For a current list of Polio-affected countries, see Global Polio Eradication Initiative.

In addition to the above, all residents and long-term visitors from Afghanistan, Pakistan, and Nigeria should be prepared to provide proof of vaccination prior to travel. Oral Polio Vaccine may be administered if travellers fail to provide proof of vaccination.


Polio, also known as Poliomyelitis, is caused by one of three poliovirus (PV) serotypes belonging to the Picornaviridae family. It is a highly contagious illness transmitted by close person to person contact, mainly through the oral-fecal route – an infected person who does not practice proper hand or body hygiene passes the infection to another person. It can also spread through infected saliva and respiratory system secretions. Polioviruses grow in the intestinal system and are shed through feces. The infection typically spreads in areas with poor water and sewage sanitation; wild poliovirus is found in this type of environment and puts unvaccinated people at risk.


As a result of global eradication efforts, Polio is now only endemic in Afghanistan, Nigeria, and Pakistan. However, countries with low vaccination rates continue to be at risk for re-introduction of the virus due to imported cases resulting from travel. Unvaccinated travellers, especially children, pregnant women, and those with a weakened immune system going to areas with Polio outbreaks are at risk.


In the majority of cases, the infection is asymptomatic – persons do not exhibit symptoms. Those that do have very mild symptoms and the infection may go unnoticed. Symptoms include fever, headache, fatigue, stiff neck, muscle pain, and vomiting. In some cases, the virus enters the bloodstream to attack the Central Nervous System which causes paralysis, usually in the legs. This is also known as Acute Flaccid Paralysis where the limbs become floppy. In severe cases, patients can become quadriplegic when the thorax and abdomen muscles become paralyzed and have difficulty breathing, swallowing, or speaking. Post-Polio Syndrome, characterized by muscle weakness, joint and muscle pain, and severe fatigue, can occur in survivors 15 to 40 years after being exposed to the virus. Treatment includes supportive care of symptoms, antispasmodic medication, physiotherapy, and even orthopedic surgery.

  • Wash your hands thoroughly and frequently with soap and water. If not available, use an alcohol-based hand sanitizer. Practice good body hygiene.

Travellers of all ages should ensure that they are up-to-date with their polio vaccination. If you have been fully vaccinated as a child, you should get a polio booster once as an adult. A primary vaccination series is necessary for those not previously or only partially vaccinated.  The inactivated injectable vaccine is available in Canada and the USA and the live attenuated oral vaccine is available in some countries. Polio-containing combination vaccines are also available for children. All provide life-time protection.
