What is the difference between hibernation, hibernation and cold rigidity in animals?

The World Health Organization (WHO) has set itself the goal of  eradicating polio  . This goal is achievable because poliomyelitis viruses are only transmitted from person to person and effective vaccines are available. Extensive immunization campaigns in developing countries where the disease persists and maintaining adequate immunization coverage in developed countries will help achieve this goal.

Europe still not completely polio free

Europe was declared a polio-free zone in June 2002 after the last disease recorded by the WHO in Europe occurred in a 33-month-old child in Turkey in 1998. However, when two new cases were reported in south-west Ukraine in September 2015, it was seen as a major setback. 

Vaccination therefore remains very important, since polio is still occurring or recurring in non-European countries. However, the disease can also be brought in by infected tourists or emigrants.

transmission of polio

Polio is an acute, transmissible infectious disease. About a week after the start of the infection, the virus is excreted with the nasopharyngeal secretion, after which – for a further three to six weeks – the virus is excreted in the stool. During this period, the disease can be transmitted to another person.

The vaccines against polio

To ensure that poliomyelitis does not return to Germany, every adult should have adequate vaccination protection. There are two vaccines against the causative agent of polio: the oral vaccine and the injection vaccine.

  • Live poliovirus vaccine according to SABIN (OPV),  the so-called oral vaccination. The oral vaccination is taken through the mouth and is therefore referred to as an oral vaccination. In the case of oral vaccination, a weakened but reproducible live vaccine is administered. These trigger an intestinal infection with the weakened viruses. In this way, vaccinated people can also infect other people with the vaccine viruses. In addition, increased side effects can occur with a live vaccine.
  • The  inactive poliovirus vaccine according to SALK (IPV),  which is injected under the skin or into the muscle. Vaccination by injection is an inactivated vaccine. The vaccine is very safe and there are almost no side effects – the administered viruses are simply not able to reproduce.

Since January 1998, the “Standing Vaccination Commission” has recommended polio vaccination only by injection with the inactivated vaccine (IPV) according to SALK® for the reasons given above.
