Preventing parent-to-child transmission (PMTCT) of HIV is crucial for reducing the burden of HIV/AIDS in children and ensuring the well-being of families affected by the virus.

PMTCT strategies aim to prevent HIV transmission from an HIV-positive mother to her child during pregnancy, childbirth, and breastfeeding. Here are key interventions and strategies to prevent parent-to-child HIV transmission:
1. Antiretroviral Therapy (ART) for HIV-Positive Pregnant Women:
- Early initiation of ART for all HIV-positive pregnant women, regardless of CD4 count or clinical stage, is recommended to suppress viral load and reduce the risk of vertical transmission.
- ART is initiated as soon as possible during pregnancy and continued throughout the breastfeeding period to maintain viral suppression.
2. Antenatal Care (ANC) and HIV Testing:
- Routine HIV testing and counseling are provided to all pregnant women during antenatal care visits, preferably during the first trimester.
- Women who test HIV-positive receive comprehensive counseling on PMTCT options, including the benefits of ART, adherence to treatment, and infant feeding practices.
3. Maternal Viral Load Monitoring:
- Regular monitoring of maternal viral load throughout pregnancy and postpartum is essential to assess treatment response and ensure viral suppression.
- Viral load testing is performed at baseline, during pregnancy (e.g., at least once every trimester), and postpartum to guide clinical management.
4. Infant Prophylaxis:
- HIV-exposed infants receive antiretroviral prophylaxis to reduce the risk of HIV acquisition during the breastfeeding period.
- Depending on national guidelines and infant HIV exposure risk, prophylactic regimens may include nevirapine or zidovudine for a specified duration, typically starting within 72 hours of birth.
5. Safe Obstetric Practices:
- Optimal obstetric practices, including elective cesarean delivery (cesarean section) for women with high viral load (>1,000 copies/mL) or other clinical indications, are recommended to reduce the risk of vertical transmission during childbirth.
- In settings where elective cesarean delivery is not feasible, intrapartum ART and other measures to minimize the risk of HIV exposure to the infant during labor and delivery are implemented.
6. Infant Feeding Counseling and Support:
- HIV-positive mothers receive counseling and support to make informed choices about infant feeding practices, taking into account individual circumstances and local context.
- Exclusive breastfeeding for the first 6 months of life, followed by timely introduction of complementary foods and continued breastfeeding with appropriate complementary feeding until at least 12 months of age, is recommended for HIV-exposed infants receiving ART.
7. Postnatal Care and Follow-Up:
- HIV-exposed infants and their mothers receive regular postnatal care, including clinical assessment, immunizations, growth monitoring, and HIV testing for infants.
- Prompt diagnosis of HIV infection in infants and linkage to appropriate care and treatment services are essential for early initiation of ART if HIV-positive.
8. Supportive Services and Psychosocial Support:
- Comprehensive support services, including psychosocial support, adherence counseling, and access to social services, are provided to HIV-positive pregnant women and their families to address barriers to PMTCT and promote retention in care.
9. Male Partner Involvement:
- Engaging male partners in PMTCT services and counseling promotes shared decision-making, adherence to ART, and support for infant feeding practices, ultimately improving PMTCT outcomes.
10. Community Engagement and Education:
- Community-based initiatives, educational campaigns, and peer support programs raise awareness about PMTCT, combat stigma and discrimination, and encourage uptake of HIV testing and treatment services among pregnant women and their families.
By implementing a comprehensive package of PMTCT interventions, including ART for pregnant women, infant prophylaxis, safe obstetric practices, and supportive services, countries can significantly reduce the risk of parent-to-child HIV transmission and achieve the goal of an AIDS-free generation. Continued investment in PMTCT programs and strategies is essential for achieving global targets for ending the HIV/AIDS epidemic by 2030.
