World Polio Day: Polio remains endemic in three countries

|

New Delhi, Oct 24: World Polio Day was established by Rotary International over a decade ago to commemorate the birth of Jonas Salk, who led the first team to develop a vaccine against poliomyelitis.

Use of this inactivated poliovirus vaccine and subsequent widespread use of the oral poliovirus, developed by Albert Sabin, led to the establishment of the Global Polio Eradication Initiative (GPEI) in 1988. As of 2013, GPEI had reduced polio worldwide by 99%.

Polio remains endemic

Polio remains endemic

Polio remains endemic in three countries Afghanistan, Nigeria and Pakistan. Neighboring Pakistan is one of only three countries in the world with ongoing wild poliovirus transmission, alongside Afghanistan and Nigeria. The country is also affected by a circulating vaccine-derived poliovirus type 2 (cVDPV2).

Until poliovirus transmission is interrupted in these countries, all countries remain at risk of importation of polio, especially vulnerable countries with weak public health and immunization services and travel or trade links to endemic countries.
