Different Types of Herpes


Herpes simplex-virus

Type 1 (HSV 1)

Herpes simplex virus 1 (HSV-1) - commonly causes herpes labialis (also called oral herpes, cold sores or fever blisters), which are highly infectious open sores that crust over before healing. Although less probable, HSV-1 can also cause genital herpes.

Type 2 (HSV 2)

Herpes simplex virus 2 (HSV-2) - a contagious viral infection primarily causing genital herpes in men and women. The telltale signs and symptoms of genital herpes include recurrent clusters of blisters, bumps and rashes in the genital areas. HSV-2 can also be responsible for herpes labialis, although lessoften than HSV-1.

Varicella-zoster virus

VZV - Acute inflammatory infection of part of the peripheral nervous system that produces painful blisters on the skin over the sites of nerves. Shingles is most common in adults over 50 years old, but it can be found in children and younger adults. Shingles occurs only in persons who have previously had chicken pox. The chicken pox virus can lie dormant for many years in the patient's nerves. When reactivated, the virus causes shingles. Symptoms of shingles include headache, fever, chills, a rash that develops into clear blisters, and moderate to severe pain in the area where the infection is active.

Epstein-Barr virus

EBV - is associated with acute infectious mononucleosis and chronic fatigue syndrome. Mononucelosis is spread by saliva and nasal secretions and is also known as the "kissing disease." Initial symptoms last up to 10 days and include fatigue, lethargy and slight fever. The acute phase of the illness lasts up to another 10 days and is marked by sore throat, high fever, enlarged lymph nodes in the neck, enlarged spleen and oftentimes, a faint, pink rash over the body. The fatigue and lethargy can last longer than other symptoms.

Cytomegalovirus

CMV; also called Human cytomegalovirus, or HCMV) - causes many diseases in humans, particularly in infants and people with compromised immune systems. Symptoms of a CMV infection include swollen glands, fever and fatigue. CMV may take the form of hepatitis, mild mononucleosis, or in newborns, jaundice and low birth weight. In severe cases of infected infants, CMV may result in brain damage, deafness, blindness and death. In people with cancer, transplanted organs, AIDS or other immune deficiencies, CMV can cause severe diseases of the lungs, colon, eye or brain.

Humand Herpes Virus 6

Causes roseola infantum--a fever leading to a pale pink body rash--most commonly in children between the ages of 6 months and 3 years. Most cases, however, are asymptomatic, occurring with fever but without a rash. In older children and adults, the virus can cause mononucleosis-like symptoms. The virus and its effects on humans are still being studied.
Human herpes viruses 7 and 8 (HHV-7 and HHV-8) - these viruses and their effects on humans are still being studied. HHV-8 is believed to be associated with Kaposi's sarcoma.
