This image was created in October, 2014, by Centers for Disease Control and Prevention (CDC), Epidemiologist, Mary Alleman, M.P.H., Ph.D., during an outbreak of wild poliovirus in the Central African nation of Cameroon, in the city of Bafoussam, the regional capital of West Region, Cameroon. The photograph depicts public health in action through a collaborative effort by the Cameroonian Ministry of Health, and the Ministry of Sports, by sponsoring this “sports walk” through Bafoussam. This type of community outreach event is held on a monthly basis, and on this occasion, was used to advertise an upcoming polio vaccination campaign. T-shirts, hats, visors, and messages delivered by way of megaphones, were used to inform the community about the campaign. This was one of the entries in the 2015 CDC Connects, Public Health in Action Photo Contest.
In 2013 and 2014, Cameroon had an outbreak of wild poliovirus. One epidemiologic aspect of a poliovirus outbreak response, is to conduct polio vaccination campaigns with high coverage of the target population. Various mass communication strategies are used to inform the population in advance of the campaigns, like the sports walk depicted here.
