The survey of British laboratories in 1970-74 was continued by a questionnaire to members of the Association of Clinical Pathologists covering the next two years. Only nine cases of hepatitis (three of hepatitis B) were reported. The annual attack rate of 34 per 100 000 was only one-quarter of that in earlier years. The findings suggest that control measures have had considerable success.
1970 - 1974年对英国实验室的调查通过向临床病理学家协会成员发放问卷得以延续，调查涵盖接下来的两年。仅报告了9例肝炎病例（3例乙型肝炎）。每10万人中34例的年发病率仅为早年发病率的四分之一。这些发现表明控制措施已取得显著成效。
