Event

An outbreak of Rift Valley Fever (RVF) is ongoing throughout Mayotte as of early March. Since the beginning of the outbreak in November 2018, health officials have confirmed at least 82 cases of the disease. Veterinarians have also confirmed 39 animal cases of the disease. In late February, officials in Mayotte banned the sale and consumption raw or unpasteurized milk. Further spread of RVF is possible in the near term.

Context

Rift Valley Fever is a viral hemorrhagic fever that is generally contracted via contact with the carcasses of infected animals, but can also be transmitted through ticks and biting midges. Symptoms generally include hemorrhagic fever, headaches, and muscle pains, while more severe symptoms include loss of sight and brain inflammation, which can cause seizures and headaches. Fatalities occur in less than 1 percent of infected individuals.

Advice

Individuals present in affected areas are advised to be extremely vigilant and to take measures to protect themselves from insect bites (e.g. by wearing covering clothing, using insect repellent, and sleeping under mosquito-netting or in an air-conditioned room). Those present in affected areas should also avoid all contact with farm animals. Individuals exhibiting any of the above symptoms should seek immediate medical attention.
