From January – May 2015, a typhoid outbreak occurred in Uganda. Pulse Lab Kampala was invited to join the National Task Force in response to the outbreak. In coordination with WHO, and in collaboration with the Ministry of Health, Pulse Lab Kampala produced a series of data visualisations to support the early response to the disease. Visualisations of weekly reports from health centres were produced with interactive maps at district, sub-county and individual health facility level. This process made it possible to explore the data using visual analytics techniques and revealing clusters of infection. The visualisations allowed decision making for the allocation of medicine, medical personnel and health centres, as well as targeting training areas.
