The World Health Organization has produced clear guidelines for the prevention of mother-to-child transmission (PMTCT) of the human immunodeficiency virus (HIV). However, ensuring that all PMTCT programme components are implemented to a high quality in all facilities presents challenges.
Although South Africa initiated its PMTCT programme in 2002, later than most other countries, political support has increased since 2008. Operational research has received more attention and objective data have been used more effectively.
In 2010, around 30% of all pregnant women in South Africa were HIV-positive and half of all deaths in children younger than 5 years were associated with the virus.
Between 2008 and 2011, the estimated proportion of HIV-exposed infants younger than 2 months who underwent routine polymerase chain reaction (PCR) tests to detect early HIV transmission increased from 36.6% to 70.4%. The estimated HIV transmission rate decreased from 9.6% to 2.8%. Population-based surveys in 2010 and 2011 reported transmission rates of 3.5% and 2.7%, respectively.
CRITICAL ACTIONS FOR IMPROVING PROGRAMME OUTCOMES INCLUDED: ensuring rapid implementation of changes in PMTCT policy at the field level through training and guideline dissemination; ensuring good coordination with technical partners, such as international health agencies and international and local nongovernmental organizations; and making use of data and indicators on all aspects of the PMTCT programme. Enabling health-care staff at primary care facilities to initiate antiretroviral therapy and expanding laboratory services for measuring CD4+ T-cell counts and for PCR testing were also helpful.
世界卫生组织已经制定了预防母婴传播(PMTCT)艾滋病毒(HIV)的明确指南。然而,确保所有设施都高质量地实施所有 PMTCT 方案组成部分都存在挑战。
尽管南非在 2002 年启动了其 PMTCT 计划,比大多数其他国家晚,但自 2008 年以来,政治支持有所增加。运营研究得到了更多关注,客观数据得到了更有效的利用。
2010 年,南非约有 30%的孕妇 HIV 阳性,5 岁以下儿童死亡的一半与该病毒有关。
2008 年至 2011 年间,接受常规聚合酶链反应(PCR)检测以早期发现 HIV 传播的 2 个月以下 HIV 暴露婴儿的估计比例从 36.6%增加到 70.4%。估计的 HIV 传播率从 9.6%下降到 2.8%。2010 年和 2011 年进行的基于人群的调查报告的传播率分别为 3.5%和 2.7%。
改善方案结果的关键行动包括:通过培训和指南传播,确保在实地层面迅速实施 PMTCT 政策的变更;确保与国际卫生机构和国际及当地非政府组织等技术合作伙伴的良好协调;并利用 PMTCT 方案所有方面的数据和指标。使初级保健设施的卫生保健工作人员能够启动抗逆转录病毒疗法,并扩大实验室服务,以测量 CD4+ T 细胞计数和 PCR 检测,这也很有帮助。
