number of _____ infections continue to occur. Infection with HBV results in an average 45 to 90 incubation period of how many days, followed by a clinical course that varies in different age groups? True or False: Over 90% of newborns True with perinatal HBV infection remain asymptomatic, while typical symptoms of acute hepatitis are observed in 15% of children aged 1 to 5 years and in 50% of older children, adolescents, and adults. Symptoms may last several weeks to several months. Most HBV-infected adults recover 6 within _____ months and develop immunity to the virus, but about 1% develop fulminant liver disease with hepatic necrosis, which has a high rate of fatality. Development of _____ HBV infection, chronic in which the virus persists in the body for six months or more, is independently related to age: chronic hepatitis B develops in about 10% of infected adults, 40% of young children, and 90% of infected infants. Is chronic HBV infection more likely to yes develop in people who are immunosuppressed or have HIV? _____ infection with HBV results in chronic inflammation and damage to the liver, and places the patient at increased risk of developing cirrhosis (seen in 20% of patients with chronic infection) or liver cancer (100 times the risk of non-HBV carriers). What hepatitis virus is a DNA virus of hepatitis B virus (HBV) the Hepadnaviridae family? How many genotypes have been 8 identified for Hepatitis B? Genotype _____ is the predominant one Cafe in the U.S and throughout the world. What is surrounded by an outer envelope Intact Virion of lipoprotein?
