This 1969 photograph depicted a Dekina, Nigerian family as they were seated in front of their home during a smallpox investigation. During the Nigerian-Biafran war, members of the CDC refugee relief team were asked to investigate the possibility of a smallpox outbreak in Dekina, which was located north of the Nigerian refugee camps. It was here that CDC’s Dr. Lyle Conrad confirmed that patients were infected with smallpox, and the CDC staff was able to contain the virus, and treat many of the victims.
