During 1979 and 1980 the Department of National Health and Welfare carried out a survey and later routine testing to determine the prevalence of serologic markers of hepatitis B in Indochinese refugees entering Canada. Between March and July 1981 the hepatitis-B-marker status of 220 selected refugees in the Ottawa-Hull area was reassessed. Overall, 173 (79%) of the participants had the same serologic markers when retested, but in 47 (21%) the markers had changed. The most significant changes were the loss of antigenemia in 22% of those who had been HBsAg-positive and the appearance of evidence of infection in 18% of those who had been seronegative. Most of these changes occurred among persons under 30 years of age, especially females aged 10 to 19 years.
1979年至1980年期间，国家卫生和福利部开展了一项调查，并随后进行了常规检测，以确定进入加拿大的印度支那难民中乙型肝炎血清学标志物的流行情况。1981年3月至7月，对渥太华-赫尔地区220名选定难民的乙型肝炎标志物状况进行了重新评估。总体而言，173名（79%）参与者重新检测时血清学标志物相同，但47名（21%）参与者的标志物发生了变化。最显著的变化是，22%曾经乙肝表面抗原阳性者的抗原血症消失，18%曾经血清学阴性者出现感染迹象。这些变化大多发生在30岁以下人群中，尤其是10至19岁的女性。
