Islamabad, Jan 15 (IANS): Pakistan has reported 71 cases of wild poliovirus type 1 (WPV1) in 2024, the National Institute of Health (NIH) said. The 71st case was confirmed on Tuesday and involved a boy from Jacobabad district in the country’s southern Sindh province, with symptoms first appearing on December 27, 2024, the Regional Reference Laboratory for Polio Eradication at the NIH said on Wednesday. The institute said that the distribution of cases includes 27 from Balochistan, 21 each from Khyber Pakhtunkhwa and Sindh, and one each from Punjab and Islamabad. The Pakistan Polio Eradication Programme has intensified its efforts to combat the resurgence of WPV1. According to the NIH, the programme conducts multiple vaccination drives annually, delivering vaccines directly to households, Xinhua news agency reported. To bolster these efforts, Pakistan will launch its first nationwide polio vaccination campaign of 2025 from February 3 to February 9, the NIH said, urging parents to ensure that all children under five receive the vaccine during the campaign. According to the World Health Organisation, Poliomyelitis (polio) is a highly infectious viral disease that largely affects children under 5 years of age. The virus is transmitted by person-to-person spread mainly through the faecal-oral route or, less frequently, by a common vehicle (e.g. contaminated water or food) and multiplies in the intestine, from where it can invade the nervous system and cause paralysis. In 1988, the World Health Assembly adopted a resolution for the worldwide eradication of polio, marking the launch of the Global Polio Eradication Initiative, spearheaded by national governments, WHO, Rotary International, the US Centres for Disease Control and Prevention (CDC), UNICEF, and later joined by the Bill & Melinda Gates Foundation and Gavi, the Vaccine Alliance. Wild poliovirus cases have decreased by over 99 per cent since 1988, from an estimated 350 000 cases in more than 125 endemic countries to 6 reported cases in 2021. Of the 3 strains of wild poliovirus (type 1, type 2 and type 3), wild poliovirus type 2 was eradicated in 1999 and wild poliovirus type 3 was eradicated in 2020. As of 2022, endemic wild poliovirus type 1 remains in two countries: Pakistan and Afghanistan.
