- Because severe illness and death have resulted from varicella in children being treated with corticosteroids, these children should avoid exposure to varicella.
- -transmitted by droplets or direct contact with a lesion and contaminated equipment also can spread the virus.
Reactivation of the virus in adults causes shingles.
a rash, described clinically as having a “dewdrop on a rose petal” pattern, scattered in clusters (crops) over the trunk, face, scalp, upper extremities, and sometimes the thighs.
After an incubation period of 2 to 3 weeks (usually 13 to 17 days), patients develop fever, malaise, anorexia, and lymphadenopathy, followed by the appearance of an extremely itchy rash that starts flat and,
over time, becomes a small blister on a red base, and then eventually forms crusted scabs.
All three stages of the rash may be present on the body at one time.
Varicella may be transmitted to others until all lesions are crusted over.
Immunization with varicella vaccine provided during infancy is designed to prevent these complications. Administration of varicella-zoster immune globulin (VZIg) within 72 hr of exposure will prevent clinical varicella in susceptible, healthy children.
Immunization with varicella vaccination is recommended.
