what type of herpes simplex virus usually produces genital infections
Herpes simplex virus Herpes simplex virus 1 and 2 (HSV-1 and HSV-2), also known as human herpesvirus 1 and 2 (HHV-1 and HHV-2), are two members of the herpesvirus family, Herpesviridae, that infect humans.[1] Both HSV-1 (which produces most cold sores) and HSV-2 (which produces most genital herpes) are ubiquitous and contagious. They can be spread when an infected person is producing and shedding the virus.
Herpesviridae There are 9 herpesvirus types known to infect humans: herpes simplex viruses 1 and 2, HSV-1 and HSV-2, (also known as HHV1 and HHV2), varicella-zoster virus (VZV, which may also be called by its ICTV name, HHV-3), Epsteinâ€“Barr virus (EBV or HHV-4), human cytomegalovirus (HCMV or HHV-5), human herpesvirus 6A and 6B (HHV-6A and HHV-6B), human herpesvirus 7 (HHV-7), and Kaposi's sarcoma-associated herpesvirus (KSHV, also known as HHV-8).[7] In total, there are more than 130 herpesviruses,[8] some of them from mammals, birds, fish, reptiles, amphibians, and mollusks.[7]
Sexually transmitted infection AIDS is among the leading causes of death in present-day Sub-Saharan Africa.[96] HIV/AIDS is transmitted primarily via unprotected sexual intercourse. More than 1.1 million persons are living with HIV/AIDS in the United States,[97] and it disproportionately impacts African Americans.[98] Hepatitis B is also considered a sexually transmitted disease because it can be spread through sexual contact.[99] The highest rates are found in Asia and Africa and lower rates are in the Americas and Europe.[100] Approximately two billion people worldwide have been infected with the hepatitis B virus.[101]
Chickenpox After a chickenpox infection, the virus remains dormant in the body's nerve tissues. The immune system keeps the virus at bay, but later in life, usually in an adult, it can be reactivated and cause a different form of the viral infection called shingles (also known as herpes zoster).[31] The United States Advisory Committee on Immunization Practices (ACIP) suggests that every adult over the age of 60 years get the herpes zoster vaccine.[32]
