Complications

In children, the disease is often mild, unless they are immunocompro-mised, so they are unlikely to experience complications. In adults (defined as 15 yr or older), the picture is rather different (32). Secondary bacterial infection is common but rarely serious. There is an increased likelihood of permanent scarring. Hemorrhagic chicken pox typically occurs on the second or third day of the rash. Usually, this is limited to bleeding into the skin, but life-threatening melena, epistaxis, or hematuria can occur.

Varicella pneumonia ranges from patchy lung consolidation to overt pneumonitis and occurs in 1 in 400 cases (33). It can occur in previously healthy individuals (particularly adults), but the risk is increased in those who smoke.

Immunocompromised people are at the greatest risk of developing this complication. It runs a fulminating course and is the most common cause of Varicella-associated death. Fibrosis and permanent respiratory impairment may occur in those who survive. Any suspicion of lung involvement is an indication for immediate treatment, and any detainee or staff member should be sent to hospital. Involvement of the central nervous system includes several conditions, including meningitis, Guillain-Barre, and encephalitis. The latter is more common in the immunocompromised and can be fatal.
