This image was created in October 2014, by Centers for Disease Control and Prevention (CDC), Epidemiologist, Mary Alleman, MPH, PhD, 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 depicted 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.
