VARICELLA ZOSTER VIRUS
The varicella-zoster virus is a member of the herpes virus family. This virus causes chickenpox, generally in children aged 2 to 10 years. Symptoms, fever, erythema (red skin), and typical eruptions develop after a 15-day incubation period. The skin is spotted with small vesicles filled with water that break open and form a crust which falls off in a week. Local antiseptics are given. Antibiotics may be prescribed in case of bacterial superinfection. A subject who had chickenpox during childhood harbors the virus in the spinal nerve nodes. During periods of stress or fatigue, the virus may become reactivated, leading to herpes zoster (zona). TEM
