Blood samples from 304 children aged 6 months to 16 years were tested by radioimmunoassay for antibodies to hepatitis A virus (anti-HAV). Of several factors examined for a possible association with the prevalence of anti-HAV--age, sex, race, geographic location and presence of malignant disease--only age showed a positive correlation with the prevalence of these antibodies.
采用放射免疫分析法对304名6个月至16岁儿童的血样进行了甲型肝炎病毒抗体(抗-HAV)检测。在检测的几个可能与抗-HAV流行率相关的因素中——年龄、性别、种族、地理位置和恶性疾病的存在——只有年龄与这些抗体的流行率呈正相关。
