[74], Secondary bacterial infection of skin lesions, manifesting as impetigo, cellulitis, and erysipelas, is the most common complication in healthy children. Chronic stress is one trigger for reactivation of the dormant virus, as it is for the closely related herpes viruses. Children younger than 12 years old and older than one month are not meant to receive antiviral drugs unless they have another medical condition which puts them at risk of developing complications. [29], Exposure to VZV in a healthy child initiates the production of host immunoglobulin G (IgG), immunoglobulin M (IgM), and immunoglobulin A (IgA) antibodies; IgG antibodies persist for life and confer immunity. Prior to 1995, when the chickenpox vaccine was introduced, nearly all U.S. children got infected with chickenpox by age 10. Both zoster and shingles derive from words for belt or girdle in Greek and Latin, respectively, referring to the typical arrangement of blisters on the torso during shingles outbreaks.

Typically, only one nerve-root cluster is involved, and the blisters appear in the area of the skin supplied by those nerves. After inhalation, chickenpox viruses invade the cells of the respiratory tract, replicate in the lymph nodes and are spread by white blood cells throughout the body. In adults, the disease is more severe,[67] though the incidence is much less common. Michael Menna, DO, is board-certified in emergency medicine. Hib vaccine : Sources: CDC, "Measles (Rubeola . Multiple subclinical reactivations of varicella zoster virus may occur spontaneously and, despite not causing clinical disease, may still provide an endogenous boost to immunity against zoster.

Bookshelf Contagiousness persists until all vesicular lesions have become dry crusts (scabs), which usually entails four or five days, by which time nasal shedding of live virus ceases. Although there have been some jumps between hosts in the distant past, these viruses tend to infect only specific hosts. Chickenpox is caused by the varicella-zoster virus (VZV). A vaccine campaign that began in the 1990s has made the disease rare in children in the U.S., but the virus lingers in the body and can reappear in unvaccinated adults years later as shingles. P.S.
