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 ...

Worldwide, the rate of infection with herpes simplex virus—counting both HSV-1 and HSV-2—is around 90%. [1] Although many people infected with HSV develop labial or genital lesions ( herpes simplex ), the majority are either undiagnosed or display no physical symptoms—individuals with no symptoms are described as asymptomatic or as having ...
There are two types of herpes simplex virus, type 1 (HSV-1) and type 2 (HSV-2). [1] HSV-1 more commonly causes infections around the mouth while HSV-2 more commonly causes genital infections. [2] They are transmitted by direct contact with body fluids or lesions of an infected individual. [1] Transmission may still occur when symptoms are not ...
There is a potential link between Alzheimer's disease and the herpes simplex virus-1 (HSV-1), which is a common cause for cold sores, a recent study suggests ... Old Navy's Break a Sweat Sale has ...
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 ...
HSV-1 can in rare cases be transmitted to newborn babies by family members or hospital staff who have cold sores; this can cause a severe disease called neonatal herpes simplex. People can transfer the virus from their cold sores to other areas of the body, such as the eye, skin, or fingers; this is called autoinoculation. Eye infection, in the ...
HSV-1 was the cause of 62.5% of cases of neonatal herpes of known type, and 98.3% of transmission was asymptomatic. [16] Asymptomatic genital HSV-1 has been shown to be more infectious to the neonate, and is more likely to produce neonatal herpes than HSV-2.
