What stopped polio?

Several key strategies have been outlined for stopping polio transmission: High infant immunization coverage with four doses of oral polio vaccine (OPV) in the first year of life in developing and endemic countries, and routine immunization with OPV and/or IPV elsewhere.

Is polio a man made disease?

The creation of the man-made polio virus came just a month after the World Health Organization had declared polio eradicated from Europe and projected total eradication of the disease by 2005. Last year, only 480 cases were reported in the world.

Where does the polio virus come from?

What are the 3 types of polio?

There are three wild types of poliovirus (WPV) – type 1, type 2, and type 3. People need to be protected against all three types of the virus in order to prevent polio disease and the polio vaccination is the best protection.
