HIV transmission to children can occur through various routes, including mother-to-child transmission (MTCT), contaminated blood products, and unsafe medical practices. Here’s an overview of key strategies for preventing HIV infection in children:
Prevention of Mother-to-Child Transmission (PMTCT):
- Antenatal Care:
- Early and regular antenatal care for pregnant women, including HIV testing, counseling, and initiation of antiretroviral therapy (ART) for those living with HIV.
- Screening for other sexually transmitted infections (STIs) and providing appropriate treatment to reduce the risk of HIV transmission.
- Antiretroviral Therapy (ART):
- Initiation of lifelong ART for pregnant women living with HIV, regardless of CD4 count or clinical stage, to suppress viral load and reduce the risk of MTCT.
- Option B+ approach, where pregnant and breastfeeding women initiate ART and continue treatment for life, regardless of CD4 count or clinical stage.
- Viral Load Suppression:
- Regular monitoring of viral load during pregnancy and postpartum period to ensure viral suppression, which significantly reduces the risk of MTCT.
- Adherence support and counseling to promote consistent use of ART and medication adherence.
- Intrapartum and Postpartum Care:
- Administration of antiretroviral prophylaxis or treatment during labor and delivery to further reduce the risk of MTCT.
- Safe delivery practices, including cesarean section for women with high viral loads or other clinical indications.
- Exclusive Breastfeeding or Formula Feeding:
- Promotion of exclusive breastfeeding for the first six months of life for HIV-exposed infants born to mothers living with HIV who are on effective ART.
- Provision of antiretroviral prophylaxis to breastfeeding infants to further reduce the risk of HIV transmission.
- Support for safe infant feeding practices, including access to clean water and formula milk for mothers who choose not to breastfeed.
Prevention of Pediatric HIV Infection:
- Prevention of Vertical Transmission:
- Early infant diagnosis (EID) of HIV-exposed infants using molecular or serological testing methods, ideally within the first six weeks of life.
- Prompt initiation of ART for HIV-infected infants diagnosed through EID to suppress viral replication and improve long-term outcomes.
- Prevention of Horizontal Transmission:
- Promotion of HIV testing and counseling for older children and adolescents, particularly those at higher risk of HIV infection.
- Provision of comprehensive sexuality education, including information on HIV prevention, safer sex practices, and condom use.
- Access to HIV prevention services such as pre-exposure prophylaxis (PrEP) for adolescents at substantial risk of HIV acquisition.
- Safe Blood Transfusion and Medical Procedures:
- Implementation of blood safety measures, including screening of blood donors for HIV and other infectious diseases, as well as routine testing of donated blood.
- Adoption of universal precautions and infection control practices in healthcare settings to prevent HIV transmission through contaminated needles, syringes, or other medical equipment.
- Community Engagement and Empowerment:
- Community-based HIV prevention programs targeting children, adolescents, and their families, including outreach, education, and support services.
- Empowerment of women and girls, including access to education, economic opportunities, and reproductive health services, to reduce vulnerability to HIV infection and promote gender equality.
Summary:
Preventing HIV infection in children requires a comprehensive approach that addresses both vertical and horizontal transmission pathways. Key interventions include early HIV testing and treatment for pregnant women, promotion of exclusive breastfeeding or safe formula feeding practices, early infant diagnosis, and access to HIV prevention services for older children and adolescents. Strengthening health systems, promoting gender equity, and addressing social determinants of health are essential components of effective HIV prevention efforts in children.
