Nigeria’s Polio Outbreak Expands — Vax Before Travel


(Vax Before Travel)

The Global Polio Eradication Initiative reported on November 17, 202, the west Africa country of Nigeria confirmed additional circulating vaccine-derived poliovirus type 2 (cVDPV2) infections.

Nigeria reported six new cases, three from Bauchi state, plus one from Gombe, Katsina, and Yobe states.

Year to date, Nigeria has reported 280 cases. However, during 2020, Nigeria reported only 8 cases.

The International Health Regulations classify Nigeria as a state infected with cVDPV2 with the potential risk of international spread. It is, therefore, subject to temporary recommendations as of August 2021.

Polio is a crippling and potentially deadly disease that affects the nervous system, says the U.S. CDC.

Because the virus that causes polio lives in the feces of an infected person, people infected with the disease can spread it to others when they do not wash their hands well after defecating.

And, people can also be infected if they drink water or eat food contaminated with infected feces.

To alert international travelers of their health risks, the CDC issued a Level 2 Travel Advisory on November 1, 2021, for the polio-belt in Africa, which includes Nigeria. 

Adult travelers that (1) previously completed the entire routine polio vaccine series, (2) have not yet received an adult booster dose, and (3) are going to any of the destinations listed should receive a single, lifetime booster dose of a polio vaccine, says the CDC.

Even those who have been sick with polio previously may need a booster dose of a polio vaccine.

Furthermore, to help prevent the international spread of polio, the World Health Organization recommends that the destinations listed require residents and long-term (4 weeks or more) visitors to show proof of polio vaccination before leaving the country.

Note: There is an outbreak of yellow fever in Nigeria. Travelers to Nigeria should take steps to prevent yellow fever by getting vaccinated at least ten days before travel.
