Children born to HIV-positive mothers who do not become infected themselves may still suffer some health problems, such as delayed growth and immune abnormalities. A research project in Benin City run by the Institute for Human Virology, Nigeria, is attempting to assess whether exposure to the virus—or to antiretroviral drugs taken by the mother and baby that thwart transmission—may cause harm. It9s difficult to separate out the many confounding variables that could lead to problems in HIV-negative babies, including the compromised health of the mothers. But the study hopes to clarify these issues by comparing 300 exposed and unexposed infants and their mothers during their first 2 years of life.

躲避艾滋病毒的婴儿可能不会毫发无损

HIV 阳性母亲所生的孩子如果自己没有被感染，可能仍会遭受一些健康问题，例如发育迟缓和免疫异常。由尼日利亚人类病毒学研究所在贝宁市开展的一项研究项目正试图评估接触该病毒或母亲和婴儿服用的阻止传播的抗逆转录病毒药物是否会造成伤害。很难区分可能导致 HIV 阴性婴儿出现问题的许多混杂变量，包括母亲的健康受损。但该研究希望通过比较 300 名暴露和未暴露的婴儿及其母亲在他们生命的前两年内澄清这些问题。
