The infectious disease is also known Polio Poliomyelitis and is now regarded as extinct, according to WHO by us. However, vaccination fatigue makes many very worried.

In the current vaccination schedule is still always the polio vaccination is recommended, but are due to the low risk of developing polio today, fewer children vaccinated. Above all travelers who spend their holidays in developing countries, should take advantage of a vaccine, because there are widely used by poor hygiene polio virus.

Disease

Polio is a viral infection of the central nervous system that can be caused by three types of polio viruses. Therefore offers a well-made disease is no lifelong protection against further infection. This would be achieved only when produced by infection with all three types of virus antibodies in the body.

The first non-specific symptoms are fever and possibly vomiting and diarrhea. After about two or three days the body temperature drops again, and it represents a short-term improvement. But after one to three days, the fever is rising again, it can cause muscles, headaches and back pain come and exhibiting the first signs of paralysis can.

The virus multiplies in the gastrointestinal tract and enters the bloodstream and into the spinal cord and the brain stem. There it sets itself, destroys nerve cells, thereby triggering paralysis of the muscles. However, paralysis and meningitis are rare, as most similar to the curve of a conventional flu or infection of the present sufferers do not even notice.

Infection and incubation

The incubation period lasts up to four weeks, and defines the time of entry of the virus until the onset of symptoms. The transmission of the polio virus is usually through the grease and droplet infection because the virus residing in the mouth and gastrointestinal tract and are excreted in the stool or by coughing. The risk of infection begins with the onset of the disease and is not over until no more polio virus are detectable in the stool.

Prophylaxis

Because the virus can not be treated with medication, vaccination is recommended. In the oral polio vaccine or the Sabin attenuated vaccine viruses are dropped onto a sugar cube and administered orally. The danger of living viruses is that they might turn back into the wild strain and can therefore cause an infection with polio virus. A good alternative is the Salk vaccine are injected with the killed viruses through a syringe into the body.
