Literature citations show that institutionalized people with Down's syndrome have a significantly higher incidence of positive hepatitis B antigen (HBsAg) than mentally handicapped people who do not have Down's syndrome. A review of 2,136 institutionalized mentally handicapped people in Georgia shows that 27% of residents who have Down's syndrome and 7% of the residents who do not have Down's syndrome tested positive for HBsAg. Forty-nine people with Down's syndrome living in the community were screened for HBsAg. Only one (3%) of 37 of the people who had never lived in an institution tested positive for HBsAg. The implication is that patients with Down's syndrome who have never been institutionalized should be treated no differently than any person in the general population who is not suspected of being a transmitter of an infectious disease.
文献引用表明，患有唐氏综合征的机构收容人员乙肝表面抗原（HBsAg）阳性率显著高于未患唐氏综合征的智力障碍者。对佐治亚州2136名机构收容的智力障碍者进行的一项回顾显示，患有唐氏综合征的居民中有27%的人HBsAg检测呈阳性，而未患唐氏综合征的居民中这一比例为7%。对49名居住在社区的唐氏综合征患者进行了HBsAg筛查。在37名从未在机构生活过的患者中，只有1人（3%）HBsAg检测呈阳性。这意味着，从未被机构收容过的唐氏综合征患者的治疗方式应与普通人群中未被怀疑为传染病传播者的任何人无异。
