What is the likely consequence of exposure to B virus carried by Old World macaque monkeys?

1. Inflammatory response

2. Severe respiratory illness

3. Meningitis

4. Gastroenteritis

The correct answer is: Meningitis

The consequence of exposure to B virus, which is primarily associated with Old World macaque monkeys, is often severe and can lead to viral meningitis in humans. B virus, scientifically known as Cercopithecine herpesvirus 1 (CHV-1), is known to cause neurological complications, particularly if there is an exposure through bites or scratches. When the virus reaches the central nervous system, it can trigger an inflammatory response in the membrane surrounding the brain and spinal cord, leading to meningitis. Symptoms may include headaches, fever, and neck stiffness, among more severe neurological presentations. While other conditions such as respiratory illness or gastroenteritis could potentially arise from other sources or infections, they are not the primary consequence linked with B virus exposure. This virus specifically impacts the nervous system, making meningitis the most direct and serious consequence of such exposure.
