Mathematical modeling of the impact of interventions (such as vaccines) has been used to develop or inform public health policies. A key parameter in modeling transmission dynamics of infectious diseases is contact data, i.e. the probability of contact between an infectious source and a susceptible individual. Patterns of social mixing and human contact differ given socio-economic and cultural backgrounds; ideally transmission models should utilize location-specific contact data. Unfortunately, there are very few studies on social contact in sub-Saharan Africa, where periodic epidemics of infectious disease continue to be a major problem. This MPRU funded study will determine "who contacts whom" and quantify age-specific contact rates in an urban and a rural location in Nigeria. This project is expected to generate contact data that will improve modeling of carriage of mucosal pathogens and disease spread in Nigerian populations.
