Prior HSV-1 seroconversion seems to reduce the symptoms of a later HSV-2 infection, although HSV-2 can still be contracted. Many people infected with HSV-2 display no physical symptoms—individuals with no symptoms are described as asymptomatic or as having subclinical herpes. [17] However, infection with herpes can be fatal. [18]
The highest HSV-2 prevalence in Central or South America—60%—has been found in Colombian middle-aged women, although similar HSV-2 prevalence has been observed in younger women in Haiti (54%). [3] HSV-2 infects about 30% of women over 30 years old in Colombia, Costa Rica, Mexico, and Panama.
The study found that valaciclovir significantly reduced shedding during subclinical days compared to placebo, showing a 71% reduction; 84% of subjects had no shedding while receiving valaciclovir versus 54% of subjects on placebo. About 88% of patients treated with valaciclovir had no recognized signs or symptoms versus 77% for placebo. [7]
Herpes simplex virus 1 (cold sores) and 2 (genital herpes) (HSV-1 and HSV-2), also known by their taxonomic names Human alphaherpesvirus 1 and Human alphaherpesvirus 2, are two members of the human Herpesviridae family, a set of viruses that produce viral infections in the majority of humans. [1] [2] Both HSV-1 and HSV-2 are very common and ...
Herpes genitalis caused by HSV-2 recurs on average four to six times per year, while that of HSV-1 infection occurs only about once per year. [ 12 ] People with recurrent genital herpes may be treated with suppressive therapy , which consists of daily antiviral treatment using acyclovir, valacyclovir or famciclovir. [ 13 ]
HSV-2 mRNA trivalent vaccine (containing gC2, gD2, gE2) Preclinical the mRNA vaccine prevented death and genital disease in 54/54 (100%) mice infected with HSV-1 and 20/20 (100%) with HSV-2, and prevented infection of the dorsal root ganglia in 29/30 (97%) mice infected with HSV-1 and 10/10 (100%) with HSV-2 [30] (update 27 July 2020) m-RNA ...

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 ...
