Since 2017 when the first monkeypox case was detected in Balyesa State after 39 years of the last outbreak in Nigeria, the disease has also been detected in other states. With the improved surveillance system, the Nigeria Centre for Disease Control (NCDC) has worked with states and partners to detect, respond and control the outbreaks.
Using the One Health approach, some of the strategies we use are enhanced case-based surveillance, deployment of multi-disciplinary response teams, development of One Health incident action plans, laboratory capacity strengthening, genetic sequencing and activation of emergency operation centres. NCDC has recently published a clinical and epidemiological report of the monkeypox outbreak in Nigeria, in the Lancet Infectious Diseases journal (see link).
In order to investigate and provide further evidence into the likely human, animal and environmental source of infection, as well as general predisposing factors and determinants of spread, NCDC is currently working with the Federal Ministry of Agriculture and Rural Development, National Veterinary Research Institute, US Centers for Disease Control and other partners. This is to carry out animal surveillance of mammals in selected states. Between July 1 and 12 2019, the Team was in Rivers state where trapping and laboratory methods were used to determine monkeypox virus prevalence in small mammals.
Currently, NCDC is working with partners to analyse the results from the field activities, which will define response activities and interventions. We are committed to strengthening the One Health approach to disease control which includes working closely with colleagues at the animal and environmental health components.
