The frequency and severity of recurrent outbreaks vary greatly between people. Some individuals' outbreaks can be quite debilitating, with large, painful lesions persisting for several weeks, while others experience only minor itching or burning for a few days. Some evidence indicates genetics play a role in the frequency of cold sore outbreaks. An area of human chromosome 21 that includes six genes has been linked to frequent oral herpes outbreaks. An immunity to the virus is built over time. Most infected individuals experience fewer outbreaks and outbreak symptoms often become less severe. After several years, some people become perpetually asymptomatic and no longer experience outbreaks, though they may still be contagious to others. Immunocompromised individuals may experience longer, more frequent, and more severe episodes. Antiviral medication has been proven to shorten the frequency and duration of outbreaks. Outbreaks may occur at the original site of the infection or in proximity to nerve endings that reach out from the infected ganglia. In the case of a genital infection, sores can appear at the original site of infection or near the base of the spine, the buttocks, or the back of the thighs. HSV-2-infected individuals are at higher risk for acquiring HIV when practicing unprotected sex with HIV-positive persons, in particular during an outbreak with active lesions.
When we say, “herpes” many of us are thinking about genital herpes, famously known as an incurable inconvenience. But there is more to it than being just a sexually transmitted infection. There are multiple ways that herpes can transmit but genital herpes is usually picked up from sexual contact. Apart from that, herpes can be transmitted when sharing an environment with someone who has the infection as well.
HSV-2 is contracted through forms of sexual contact with a person who has HSV-2. An estimated 20 percent of sexually active adults in the United States are infected with HSV-2, according to the American Academy of Dermatology (AAD). HSV-2 infections are spread through contact with a herpes sore. In contrast, most people get HSV-1 from an infected person who is asymptomatic, or does not have sores.
"Oral herpes is an infection found in the mouth, or on and around the lips, caused by the Herpes Simplex Virus (HSV)," Michael explains. "There are two types or strains of this virus called HSV1 and HSV2. Usually, the HSV1 strain infects the mouth and lips, and the HSV2 strain infects the genitals. It is however possible for HSV2 to infect your mouth and lips."
