How does that compare to the incident rate of herpes simplex in the US adult population? According to the CDC, worldwide adult infedtion rate is between 65 and 90 percent among humans. So I'd say the monkeys are best told to stay away from those nasty humans!
Worldwide rates of either HSV-1 and/or HSV-2 are between 60-95% in adults.[2] HSV1 is more common than HSV2 with rates of both increasing as people age.[2] HSV-1 rates are between 70% to 80% in populations of low socio-economic status and 40% to 60% in populations of improved socio-economic status.[2] Prevalence of HSV-2 is those between the ages of 15 and 50 is approximately 535 million as of 2003 or 16% of the population with greater rates among women and in those in the developing world.[67] Rates of infection are determined by the presence of antibodies against either viral species.[68] An estimated 536 million people worldwide were infected with HSV-2 in 2003, with the highest rates in sub-Saharan Africa and the lowest rates in western Europe.[69]
B virus infection is caused by Macacine herpesvirus 1 (formerly Cercopithecine herpesvirus 1 [CHV-1]), an alphaherpesvirus closely related to herpes simplex virus. B virus is also commonly referred to as herpes B, monkey B virus, herpesvirus simiae, and herpesvirus B.
The virus is commonly found among macaque monkeys, including rhesus macaques, pig-tailed macaques, and cynomolgus monkeys (also called crab-eating or long-tailed macaques), any of which can harbor latent B virus infection and appear to be natural hosts for the virus. Monkeys infected with B virus usually have no or only mild symptoms. In addition, rabbits, guinea pigs, and mice can be experimentally infected with B virus.
Infection with B virus is extremely rare in humans; however, when it does occur, the infection can result in severe neurologic impairment or fatal encephalomyelitis if the patient was not treated soon after exposure.
Because the simian version of herpes infection is generally fatal to humans.
Even with prompt treatments (Acyclovir, etc.) the odds of full recovery are dicey.
Because if you get bitten by a monkey with Herpes B you have a wonderful chance of dying....
