Rabies Outbreak in South Africa’s Marine Mammals

South African scientists have made a groundbreaking discovery, identifying what is believed to be the world’s first outbreak of rabies in marine mammals. The finding has prompted Cape Town authorities to urge the public to exercise caution when interacting with fur seals.

In Cape Town, South Africa, it is not uncommon for people to approach fur seals when they come ashore. However, experts warn that if individuals are bitten by these animals, they may be at risk of contracting rabies.

According to recent research, at least 24 fur seals that died or were euthanized at multiple locations on the west and south coasts of the country tested positive for rabies. This discovery originated from a dog that was infected after being bitten by a fur seal on a Cape Town beach in June.

The authorities then conducted genetic analysis on brain samples from over 100 fur seal carcasses collected in recent years. The results suggest that the outbreak was likely transmitted by jackals in neighboring Namibia, which then spread among fur seals.

Historically, there has been only one recorded instance of marine mammals being infected with rabies – a ringed seal in Norway in the early 1980s. However, experts believe that this case was transmitted by an Arctic fox, and there was no evidence of an outbreak among seals.

Rabies is a serious disease that can be transmitted to humans through saliva and other routes, such as bites. If left untreated, it can be fatal. In response to the outbreak, Cape Town authorities have vaccinated some fur seals in the port and warned the public to avoid approaching them.

Precautions and Prevention

To minimize the risk of contracting rabies, it is essential to exercise caution when interacting with fur seals and other marine mammals. The public is advised to:

• Avoid approaching or touching fur seals, even if they appear healthy.
• Keep a safe distance from fur seals, at least 10 meters (33 feet) away.
• Not feed or attempt to feed fur seals, as this can increase the risk of bites.
• Wash hands thoroughly after coming into contact with fur seals or their saliva.

By taking these precautions, we can reduce the risk of rabies transmission and protect both humans and marine mammals.
