Herpes simplex is a common viral infection that causes recurring clusters of small, painful blisters on the skin or mucous membranes, most often around the mouth or genitals. The virus stays in the body for life and can reactivate from time to time, especially during stress, illness, or other triggers.
This is general information. With a scan you'll receive a detailed, personalized analysis — including individual risk assessment, progression tracking and recommended actions.
Herpes simplex is caused by infection with HSV‑1 or HSV‑2, usually spread through direct skin or mucous membrane contact, kissing, or sexual contact. After the first infection, the virus remains in nerve cells and can reactivate with triggers like illness, stress, fatigue, or local irritation.
Anyone who has close contact with an infected person can get herpes simplex, especially through kissing or sexual contact. People with weakened immune systems, frequent stress, or other illnesses tend to have more frequent or severe outbreaks.
Herpes simplex is treated with antiviral tablets or creams such as acyclovir, valacyclovir, or famciclovir, which shorten outbreaks and reduce symptoms. Pain relief, gentle skin care, and sometimes long‑term suppressive antiviral therapy are used to control frequent or severe recurrences.
You can lower your risk of herpes outbreaks and transmission by avoiding direct contact with blisters, using condoms or dental dams, and not sharing items like lip balm during an active flare. Managing triggers such as stress, illness, and strong sun exposure also helps reduce recurrences.
See a doctor for suspected first‑time genital herpes, very painful or widespread outbreaks, eye involvement, or if you have a weak immune system or are pregnant. A doctor can confirm the diagnosis with tests, prescribe antivirals, and discuss ways to reduce recurrences and transmission.
Most herpes simplex outbreaks are not an emergency and can be managed with routine medical care, especially if you’re otherwise healthy. Seek urgent care if you have eye symptoms, severe headache or confusion, rapidly spreading rash, or if you’re pregnant or immunocompromised with a new severe outbreak.

Genital herpes is a sexually transmitted infection caused by herpes simplex virus types 1 or 2. It usually shows up as painful blisters and sores on or around the genitals, anus, or nearby skin. The virus stays in the body for life and can flare up again from time to time. Treatment can’t remove the virus, but it can shorten outbreaks, ease symptoms, and reduce the risk of passing it on.
Chickenpox is a highly contagious infection caused by the varicella zoster virus, usually affecting children. It starts with fever and tiredness, followed by an itchy red rash that turns into fluid-filled blisters and then crusts. In healthy kids it usually clears on its own in about 7–10 days, but it can be dangerous for infants, pregnant women, adults, and people with weak immune systems. After chickenpox, the virus stays in the body and can later cause shingles.
Trichomycosis is a fungal infection that affects hair and hair follicles, most often on the scalp (tinea capitis) or in the beard area (tinea barbae). It can cause patches of hair loss, flaking, redness, pustules, and sometimes permanent scarring if not treated in time.
Onychomycosis is a fungal infection of the fingernails or toenails that makes them thick, discolored, and brittle. It usually develops slowly and is not dangerous, but it rarely clears on its own and often needs months of treatment. Toenails are affected more often than fingernails, especially in adults and older people. Early diagnosis and treatment help prevent permanent nail damage and spread to other nails or skin.
