Cape fur seals with rabies infect 7 in South Africa

Rabies outbreak linked to string of attacks on surfers and beachgoers

Vaccinations to be trialed to contain outbreak

For the last three years, scientists in South Africa have been trying to unravel a grim marine mystery. A string of fur seal attacks on surfers and beachgoers in Cape Town has been linked to an outbreak of rabies, with 11 seals testing positive for the virus.

Reports of Cape fur seals showing aggressive behavior, especially towards people, have increased since several mass mortality events occurred in 2021 and 2022. In response, the South African National Parks (SANParks) has been monitoring the situation and collecting samples from seals for testing.

In June 2024, the first confirmed case of rabies in a Cape fur seal was reported. Since then, 10 more seals have tested positive for the virus. All of the infected seals were found along a 400-mile stretch of coastline from Cape Town to Port Elizabeth.

Rabies is a fatal disease that affects the central nervous system. It is transmitted through the saliva of infected animals, and can be transmitted to humans through bites or scratches. The virus can cause a range of symptoms, including fever, headache, muscle weakness, and paralysis. If left untreated, rabies can be fatal.

The outbreak of rabies in Cape fur seals is a serious concern for both human and animal health. SANParks is working to contain the outbreak and prevent further infections. Vaccinations will be trialed to try to contain the outbreak and protect seals and people from the virus.

In the meantime, people are advised to avoid contact with Cape fur seals and to report any aggressive behavior to SANParks.
