Severe and even fatal varicella has been reported in otherwise healthy children on high-dose corticosteroids (e.g., 2 milligrams per kilogram per day or more of prednisone or equivalent) for treatment of asthma and other illnesses. In studies of household contacts, several instances of asymptomatic seroconversion have been observed. Primary varicella infection (chickenpox) was not reliably distinguished from smallpox until the end of the 19th century. Centers for Disease Control and Prevention. WebIgG titers against viruses were affected by vaccination programs. 32 38 High seroconversion rates of 94100% have been shown six to eight weeks after a single VZV vaccination in children 26 28 and two doses in The reason(s) for this difference in age distribution are not known with certainty. High rates of vaccination coverage in the United States have eliminated discernible seasonality of varicella. The most frequent complications in immunocompromised persons are pneumonia and encephalitis. For persons age 13 years or older, the minimum interval between doses is 4 weeks. MMWR 2010;59(No. WebNegative test results mean that no signs of measles or mumps were found in your sample.
