Lagos State

lagos State is a densely populated coastal metropolis with an estimated population of over 21 million people, serving as a sentinel site for the National Malaria Elimination Programme (NMEP) drug efficacy studies in Nigeria. Malaria remains a significant public health concern, but Lagos has made remarkable progress in controlling the disease – with a reported prevalence of 1.3 % in early 2025, placing the state on track for malaria pre-elimination as defined by the World Health Organization (WHO). However, malaria still accounts for a large share of febrile illnesses seen in facilities and the recent report of Plasmodium vivax detection in Lagos highlights ongoing surveillance needs even as overall transmission declines.
