Neonatal herpes simplex, or simply neonatal herpes, is a herpes infection in a newborn baby, caused by the herpes simplex virus (HSV). It occurs mostly as a result of vertical transmission of the HSV from an affected mother to her baby. [ 2 ]
Herpes simplex virus 1 infects humans, most often as cold sores. It is very common and contagious; about 67% of the world population under the age of 50 has Herpes simplex virus 1. [5] It is often acquired orally during childhood.
Herpes gladiatorum is one of the most infectious of herpes-caused diseases, and is transmissible by skin-to-skin contact. The disease was first described in the 1960s in the New England Journal of Medicine. It is caused by contagious infection with human herpes simplex virus type 1 (HSV-1), [1] which more commonly causes oral herpes (cold sores).
Nine herpesvirus types are known to primarily infect humans, [7] at least five of which are extremely widespread among most human populations, and which cause common diseases: herpes simplex 1 and 2 (HSV-1 and HSV-2, also known as HHV-1 and HHV-2; both of which can cause orolabial and genital herpes), varicella zoster (VZV or HHV-3; the cause ...
Another analysis has estimated the mutation rate in the herpes simplex 1 genome to be 1.82×10 −8 nucleotide substitution per site per year. This analysis placed the most recent common ancestor of this virus ~710,000 years ago. [62] Herpes simplex 1 and 2 diverged about 60]
Roseola, also known as sixth disease, is an infectious disease caused by certain types of human herpes viruses. [2] Most infections occur before the age of three. [1] Symptoms vary from absent to the classic presentation of a fever of rapid onset followed by a rash.
About 90% of cases of herpes encephalitis are caused by herpes simplex virus-1 (HSV-1), the same virus that causes cold sores. According to a 2006 estimate, 57% of American adults were infected with HSV-1, [3] which is spread through droplets, casual contact and sometimes sexual contact, though most infected people never have cold sores.
