DRC: WHO expresses concerns over nationwide polio outbreak

Event

The World Health Organization (WHO) has expressed concern over a polio outbreak affecting Haut-Lomami, Tanganyika, Maniema, Ituri, and Haut-Katanga provinces. WHO officials have warned that there is a high risk of the outbreak spreading nationally and medium risk of it spreading internationally. At least 29 confirmed cases were reported between June 2017 and June 2018.

Context

Poliomyelitis is an acute communicable disease caused by a human enterovirus of the Picornaviridae family. Poliovirus is transmitted from one person to another by oral contact with secretions or fecal material from an infected person. Most poliovirus infections cause asymptomatic viral replication that is limited to the alimentary tract. However, following an incubation period of approximately 7-10 days (although it can range 4-35 days), about 24 percent of those infected develop clinical signs such as fever, headache, and sore throat (considered a minor illness).

Advice

Individuals in the DRC are advised to verify their vaccination status and monitor the situation.
