Senegal has organised a multisectoral response to a growing Rift Valley fever outbreak. The campaign, announced at a press conference on 20 October in Dakar, involves the ministries of health, agriculture, environment and water resources. Minister Ibrahima Sy stressed that the disease affects human, animal and environmental health and needs a collective response.
Since the outbreak began in September, epidemic management committees have been activated across the country. The Ministry of Health had tested 1,657 samples and confirmed 258 human cases as of 20 October; 21 people died and 192 have recovered. Authorities confirmed 57 animal cases and say more than 14,000 animals have been vaccinated. Specialised working groups, including zoonoses experts, support decision-making.
Mosquito control is under way in high-risk areas with breeding site destruction, impregnated nets and drone reconnaissance. Officials warn that self-medication and delayed hospital admission contributed to several deaths, including cases with haemorrhaging and organ failure. There is no human vaccine, but effective vaccines exist for animals. PCR tests are used for diagnosis, though more point-of-care tests are needed.
