POLIO
The disease is caused by the polio virus, often spread through food or water that has been contaminated with infected feces especially in areas where sanitation is poor. The virus may also be transmitted via respiratory droplets coughed by an infected person.
Initial symptoms include fever, headache, nausea and vomiting. The virus mainly affects children under five and will reach the central nervous system of approximately one out of every 100 patients, causing some form of paralysis.
There is no known drug that can treat the disease. Prevention includes avoidance of source and good personnel hygiene in areas of polio outbreaks. All travelers and personnel working in areas of outbreaks are advised to be fully immunized against polio.
Primary vaccination Primary vaccination against polio is usually given in childhood. Vaccination consists of four doses of oral (OPV) or injected (IPV) vaccine. Those who have had a primary vaccination with either IPV or OPV during childhood should have another dose of vaccine. This will give life-long immunity.
Those with uncertain immunity or who are unvaccinated or uncertain of their vaccination status should be vaccinated before traveling. Two doses of vaccine should be administered four to eight weeks apart. A third dose should be administered six to 12 months after the second dose.
If eight weeks or more remain before travel: give three doses, each separated by four weeks. If four to eight weeks remain before travel: give two doses, each separated by four weeks. If less than four weeks remain before travel, give one dose of vaccine.
In all cases, the remaining doses should be given later at the recommended intervals.
