Although the varicella virus causes both chicken pox and shingles, the two have different symptoms and distinct rashes. It used to cause an estimated 4 million cases of illness, 11,000 hospitalizations, and 100 deaths each year in the United States. The fluid inside the pox blisters also can spread the infection. A look at how herpes viruses can cause serious eye problems. One of the viruses that causes herpetic eye disease is the varicella-zoster virus. It also causes chickenpox and the nervous system disease shingles. When this virus affects the eye, it is called herpes zoster ophthalmicus. Shingles, also known as zoster or herpes zoster, is a painful skin rash. It is caused by varicella zoster virus (VZV), the same virus that causes chickenpox. Shingles is not caused by the same virus that causes genital herpes, a sexually transmitted disease.
VZV only affects humans, and commonly causes chickenpox in children, teens and young adults and herpes zoster (shingles) in adults and rarely in children. Many years after the patient has recovered from chickenpox, VZV can reactivate to cause a number of neurologic conditions. VZV also fails to produce the LAT (latency-associated transcripts) that play an important role in establishing HSV latency (herpes simplex virus). Chickenpox is a highly contagious disease caused by primary infection with the varicella-zoster virus. It may be stimulated to reappear later as herpes zoster (shingles). Some children may also experience additional symptoms such as high fever, headache, coldlike symptoms and vomiting and diarrhoea. Shingles is an infection of a nerve area caused by the varicella-zoster virus. It causes pain and a rash along a band of skin supplied by the affected nerve.
What is the varicella-zoster virus and how does it cause shingles? This second eruption of the chickenpox virus is called shingles or herpes-zoster. The vaccine also reduced the number of cases of long-lasting nerve pain (postherpetic neuralgia) by two-thirds compared with the placebo. Shingles may also cause fever, headache, chills and an upset stomach. Shingles, also called zoster or herpes zoster, is a skin rash caused by a viral infection of the nerves just below the skin. Causes. Shingles and chickenpox are both caused by the varicella zoster virus.
Varicella Zoster Virus
Also, an extensive listing of AIDS-related internet web site addresses. The culprit behind chickenpox and shingles is a herpesvirus called varicella zoster virus. After initial infection, chickenpox, also known as varicella, can invade the nervous system and stay dormant for many years, only to reactivate and return to the skin as shingles, or zoster. The enveloped virus infects the sensory nerves without causing any damage and travels to the sensory ganglia where it becomes latent. The varicella-zoster virus has the potential to cause two diseases: chickenpox (varicella) and shingles (herpes zoster). It can also be spread indirectly through contact with contaminated, freshly soiled items, such as clothing, of an infected individual.
