B Virus: A Rare but Deadly Infection to Watch Out For

The B virus, also known as Cercopithecine herpesvirus 1 (CHV-1), is a rare but highly contagious virus primarily found in macaque monkeys. Occasionally, it can be transmitted to humans, usually through direct contact with the saliva, blood, or other bodily fluids of an infected monkey. While human infections are uncommon, they can have devastating consequences.

The virus can cause a range of symptoms in humans, including fever, chills, headache, muscle aches, and nausea. In severe cases, it can lead to encephalitis, a dangerous brain infection that can cause seizures, coma, and even death. The fatality rate for human B virus infections is estimated to be around 70%.

The B virus is primarily a concern for people who work with or come into close contact with macaque monkeys, such as researchers, zookeepers, and veterinarians. However, even casual contact with infected monkeys can pose a risk. In 2022, a woman in the United States died from the B virus after being bitten by a pet macaque she had purchased online.

There is no specific treatment for the B virus, but antiviral medications may be used to reduce the severity of symptoms. Prevention is critical, and people who may be exposed to the virus should take precautions such as wearing gloves, masks, and protective clothing. Macaque monkeys should be vaccinated against the virus, and people who are bitten or scratched by a monkey should seek medical attention immediately.

The B virus is a reminder that even rare infections can be deadly. It is essential to be aware of the risks and take precautions to protect yourself if you are working with or near macaque monkeys.
