An intervention study was done over two years in seven Gambian villages to determine the contribution of bedbugs to hepatitis B transmission. In addition, fortnightly questionnaires were completed for each child to assess other possible routes of transmission. The intervention, insecticide spraying of the child's dwelling, was highly effective in reducing exposure to bedbugs but there was no effect on hepatitis B infection. No other risk factor for transmission was identified despite a consistent village-to-village variation in the rate of childhood infection. The major mode of transmission of hepatitis B in childhood remains unknown.
在冈比亚的七个村庄进行了一项为期两年的干预研究，以确定臭虫对乙型肝炎传播的影响。此外，每两周为每个孩子填写问卷，以评估其他可能的传播途径。干预措施是对孩子的住所进行杀虫剂喷洒，这在减少接触臭虫方面非常有效，但对乙型肝炎感染没有影响。尽管儿童感染率在不同村庄之间存在持续差异，但未发现其他传播风险因素。儿童期乙型肝炎的主要传播方式仍然未知。
