The tragic spread of Ebola virus in Africa has been discussed at length as a failure of public health systems resulting from inept governance and from poverty. However, a root cause of the epidemic lies in the rapid and unchecked population growth in Africa. Unlike developing countries in other parts of the world, African nations currently do not seem to be undergoing the ‘demographic transition’ that associates rising GDPs with falling fertility (1). The rapid increase in population sets the stage for transmission of diseases such as Ebola in two ways. First, by migration of people from overcrowded agricultural land to forest areas where more contact with animal disease vectors is possible. Second, by the ever-increasing populations in congested urban slum area where disease transmission is facilitated. Effective control of infectious disease epidemics in Africa (and elsewhere) must including more aggressive family planning services.
