Senegal has launched a nationwide, multisectoral response to a growing Rift Valley fever outbreak, announced at a press conference on Monday 20 October in Dakar. The response joins the ministries of health, agriculture, environment and water resources and aims to protect both people and animals. Minister Ibrahima Sy described the disease as lying at the crossroads of human, animal and environmental health, and said a collective response is essential.
Since the outbreak began in September, the government activated epidemic management committees, increased case detection and clinical care, and rolled out livestock vaccination campaigns. As of 20 October the Ministry of Health had tested 1,657 samples and confirmed 258 human cases; 21 people died and 192 recovered. Authorities reported 57 confirmed animal cases and said more than 14,000 animals have been vaccinated. Specialised working groups, including zoonoses experts, have been formed to advise on measures.
Mosquito control operations focus on destroying breeding sites, using impregnated nets and deploying drones to locate stagnant water. Vaccination is prioritised in livestock markets, at water points and along routes used to move animals to graze, according to Mawlouth Diallo of the Pasteur Institute of Dakar. Health teams have intensified surveillance in Saint-Louis, Matam, Louga, Thiès and Tambacounda. Officials warned that self-medication and late hospital admission contributed to several deaths, some from haemorrhaging or organ failure, and urged people not to self-medicate.
Experts discussed research and diagnostic gaps at an open scientific consultation convened by the UK Health Security Agency on 14 October. Emmanuel Agogo of FIND said analysis found "huge gaps in point-of-care tests." PCR is used for diagnosis, but lateral flow and antigen tests are largely lacking. Specialists called for continued genomic monitoring and better measures to protect veterinarians and field teams, including improved mobile laboratory solutions used elsewhere.

Discussion questions
- What are the benefits and possible difficulties of a multisectoral response to an outbreak like this?
- How could improved point-of-care and lateral flow tests change the local response to the disease?
- What measures would you prioritise to protect veterinarians and field teams working during this outbreak, and why?
