title: [A study on the secondary infection in families in which hepatitis A patients were isolated and treated in hospitals and those in which patients stayed at home].
abstract: This study was conducted during the epidemic season in Hang Zhou, zhejiang in the spring of 1988. HAV infection rates were compared between close contacts of the hepatitis A patients isolated in hospitals and those stayed at home. It was found that there was significant difference between the HAV infection rates in the group of close contacts of hepatitis A patients who have been hospitalized within 5 days and those in the group stayed at home or those in other groups. Whereas the HAV infection rates in the group of close contacts of HA patients remained at home were not significantly different from those in other groups. The results showed that HA patients had to be isolated and treated in hospital early. HAV inapparent infection rate was 86.21% in this study. The ratio between HAV apparent infection and inapparent infection was 1:6.25.
