Equatorial Guinea reports fifth polio case of the year; additional cases reported in Nigeria, Pakistan
Three new wild poliovirus type 1 (WPV1) were reported during the past week, according to the Global Polio Eradication Initiative (GPEI) today.
One additional case was reported from Equatorial Guinea from the previously uninfected Mbini district in Litoral province and had onset of paralysis on 3 May. This is the fifth case reported from the African country in 2014.
The cases are linked to an ongoing outbreak in neighboring Cameroon, which has reported four cases in 2013 and three cases in 2014.
Last week, Brazil reported that a wild poliovirus type 1 (WPV1) had been detected in a sewage sample collected in March 2014 at Viracopos International Airport in Sao Paolo state. Genetic sequencing indicates that this virus is most closely related to the virus that is circulating in Equatorial Guinea.
In Nigeria, as previously reported on The Global Dispatch, one new WPV1 case was reported in the past week from the previously uninfected Sumaila LGA, Kano state, with onset of paralysis on 17 May. The total number of WPV1 cases for 2014 is four.
Pakistan recorded one additional case from North Waziristan, Federally Administered Tribal Areas (FATA) with onset of paralysis on 28 May. The total number of WPV1 cases reported from Pakistan for 2014 is 83.
Globally, the total polio cases reported to date is 106. For more infectious disease news and information, visit and “like” the Infectious Disease News Facebook page
