    Certain infectious and parasitic diseases
Clinical Information
  • A group of acute infections caused by herpes simplex virus type 1 or type 2 that is characterized by the development of one or more small fluid-filled vesicles with a raised erythematous base on the skin or mucous membrane. It occurs as a primary infection or recurs due to a reactivation of a latent infection. (Dorland, 27th ed.)
  • Herpes is an infection that is caused by a herpes simplex virus (hsv). Oral herpes causes cold sores around the mouth or face. genital herpes affects the genitals, buttocks or anal area. Genital herpes is a sexually transmitted disease (std). It affects the genitals, buttocks or anal area. Other herpes infections can affect the eyes, skin, or other parts of the body. The virus can be dangerous in newborn babies or in people with weak immune systems. There are two types of hsv:
    • hsv type 1 most commonly causes cold sores. It can also cause genital herpes.
    • hsv type 2 is the usual cause of genital herpes, but it also can infect the mouth.
    hsv spreads direct contact. Some people have no symptoms. Others get sores near the area where the virus has entered the body. They turn into blisters, become itchy and painful, and then heal.most people have outbreaks several times a year. Over time, you get them less often. Medicines to help your body fight the virus can help lessen symptoms and decrease outbreaks.
  • Infection caused by the herpes simplex virus; affects the skin and nervous system; produces small temporary (but sometimes painful) blisters on the skin and mucous membranes.
