Herpes is a common viral infection in people, especially those with weak health or reduced immunity. This disease can occur in people of all ages, whether male or female. In many cases, people with herpes often feel embarrassed and do not dare to see a doctor, even though the disease can be treated and prevented.

What is herpes?
Herpes is an infectious disease caused by a type of virus that can affect the skin and mucous membranes in the body. This disease is common in all ages and genders and may make patients feel embarrassed or afraid to see a doctor, even though in fact, herpes can happen to anyone, especially those with poor health.
The transmission of herpes occurs through direct contact, such as contact with lymph from blisters, sharing personal items such as drinking glasses, towels, or having unprotected sex. In addition, touching things in public while the body is weak can also cause infection.
Causes of herpes
Herpes is caused by a type of virus called Herpes Simplex Virus (HSV), which can be divided into 2 main types:
Herpes Simplex Virus Type 1 (HSV-1)
HSV-1 usually causes infection in areas above the waist, especially the mouth, lips, and nose. HSV-1 infection can occur in the following cases:
- Weak immunity, such as when the body is tired, stressed, or does not get enough rest.
- Contact with an infected person, such as sharing items such as drinking glasses, lipstick, or contaminated towels.
- During recovery from an illness Or women during menstruation, which is a period when the body is weak.
- A common example is herpes on the mouth, which is a small blister that occurs on the lips or around the mouth.

Locations where HSV-2 infection is found include:
- Vaginal and cervix in women
