Monkey B Virus

Monkey B Virus


China has reported its first human infection with Monkey B Virus (BV) and subsequent death.

Initially isolated in 1932, Monkey BV is an alphaherpesvirus enzootic in macaques. B virus is the only identified old-world-monkey herpesvirus that displays severe pathogenicity in humans.


Transmission - Macaque monkeys commonly have this virus, and it can be found in their saliva, feces, urine, or brain or spinal cord tissue.


The virus may also be found in cells coming from an infected monkey in a lab. B virus can survive for hours on surfaces, particularly when moist.

In Humans - BV is transmitted via direct contact and exchange of bodily fluid secretions of monkeys. The infection has a fatality rate of 70% to 80%. 


BV has a propensity to invade the Central Nervous System when transmitted to humans.


Symptoms - The initial symptoms usually develop around 1-3 weeks after exposure to the virus.


The first indications of B virus infection are typically flu-like symptoms, following which an infection person may develop small blisters in the wound or area on the body that came in contact with the monkey.


Some other symptoms of the infection include shortness of breath, nausea and vomiting, abdominal pain and hiccups.


As the disease progresses, the virus causes inflammation of the brain and spinal cord, leading to neurologic and inflammatory symptoms; issues with muscle coordination; and in extreme cases, death.


Currently, there are no vaccines that can protect against BV infection.


Risk - The virus might pose threat to laboratory workers, veterinarians, and others who may be exposed to monkeys or their specimens.
