Circulating vaccine-derived Type 2 poliovirus occurs when the live weakened in OPV genetically changes, circulates, and causes polio. Cases are rare and can occur in populations with under-immunized children. However, cVDPV has been circulating for many years in Nigeria.
The NEOC is the government body charged with the mandate of overseeing Nigeria’s polio eradication effort. It consists of government and implementing partners such as the CGPP, WHO, CDC, UNICEF, Rotary, and the Bill & Melinda Gates Foundation.
“Follow the virus” means conducting immunization responses (such as polio campaigns and outbreak responses) by focusing on populations located in areas where the virus has been detected in children younger than 5 years.
Three doses of pentavalent vaccine provide protection against diphtheria, pertussis, tetanus, hepatitis B, and Haemophilus influenzae type B.
Iftar is the Muslim “breaking of the fast” that occurs at dusk during Ramadan. Ramadan is the Islamic month of fasting, which is practiced from sunrise to sunset.
Ramadan is the ninth month of the Islamic calendar during which time Muslims fast during daylight hours to commemorate the revelation of the Quran to Muhammad.
Imams are Muslim religious leaders who lead prayers in mosques.
Two cases of AFP from non-polio causes among 100,000 children younger than 15 years are normally expected in a 12-month period.
Community informants conduct passive surveillance. Traditional birth attendants, bone setters, traditional healers, spiritual leaders, and barbers act as informants.
The community case definition used by community informants and VCMs are three-prong: children who are younger than 15 years and have sudden weakness in an arm or leg and the limb is floppy.
The CGPP team consists of a volunteer community mobilizer, a volunteer ward supervisor, and an LGA Coordinator.
One community leader remarked: “Ba wanda yataba zuwa ya wayar mana da kai kamar yanda kukayi saboda haka a madadin mutanen garin zamu cigabada karban alluran rigakafi a koyaushe idan mutanan sukazo,” meaning “no other person tried to explain these issues patiently before now, but now we will allow our children to be vaccinated.”
