HSV-2 seroprevalence in pregnant women between the ages of 15 and 44 in British Columbia is similar, with 57% having antibodies for HSV-1 and 13% having antibodies for HSV-2. [3] In British Columbia in 1999, the seroprevalence of HSV-2 antibody in leftover serum submitted for antenatal testing revealed a prevalence of 17.3%, ranging from 7.1% ...
[1] [2] Both HSV-1 and HSV-2 are very common and contagious. They can be spread when an infected person begins shedding the virus. As of 2016, about 67% of the world population under the age of 50 had HSV-1. [3] In the United States, about 47.8% and 11.9% are estimated to have HSV-1 and HSV-2, respectively, though actual prevalence may be much ...
HSV is classified into two types, HSV-1 and HSV-2. [1] While historically HSV-2 was more common, genital HSV-1 has become more common in the developed world. [1] [7] Diagnosis may occur by testing lesions using either PCR or viral culture or blood tests for specific antibodies. [1] Efforts to prevent infection include not having sex, using ...

The annual incidence in Canada of genital herpes due to HSV-1 and HSV-2 infection is not known (for a review of HSV-1/HSV-2 prevalence and incidence studies worldwide, see Smith and Robinson 2002). As many as one in seven Canadians aged 14 to 59 may be infected with herpes simplex type 2 virus [ 89 ] and more than 90 per cent of them may be ...
Human alphaherpesvirus 2 is periodically shed in the human genital tract, most often asymptomatically. Most sexual transmissions occur during periods of asymptomatic shedding. [ 5 ] Asymptomatic reactivation means that the virus causes atypical, subtle, or hard-to-notice symptoms that are not identified as an active herpes infection, so ...
[1] [2] [3] The members of this family are also known as herpesviruses. The family name is derived from the Greek word ἕρπειν ( herpein 'to creep'), referring to spreading cutaneous lesions, usually involving blisters, seen in flares of herpes simplex 1, herpes simplex 2 and herpes zoster ( shingles ).

Oral HSV-2 shedding is rare, and "usually noted in the context of first episode genital herpes." [21] In general, both types can cause oral or genital herpes. [22] [23] [24] Cold sores are the result of the virus reactivating in the body. Once HSV-1 has entered the body, it never leaves.
