Summary
Universal voluntary human immunodeficiency virus (HIV) screening during prenatal care significantly increases testing rates. This approach, combined with free zidovudine (AZT) treatment, dramatically reduces perinatal HIV transmission.
Area of Science:
- Obstetrics and Gynecology
- Infectious Diseases
- Public Health
Background:
- Childbearing-aged women face increased human immunodeficiency virus (HIV) infection risk.
- Prenatal screening for HIV is a critical public health strategy.
- Voluntary screening during pregnancy is recommended to mitigate transmission.
Purpose of the Study:
- To evaluate the impact of voluntary HIV screening in pregnant women.
- To assess the effectiveness of universal screening with informed refusal.
- To determine the effect of zidovudine (AZT) treatment on perinatal HIV transmission.
Main Methods:
- Implemented voluntary HIV testing for prenatal patients from January 1992.
- Transitioned to universal screening with informed refusal in July 1993.
- Offered free zidovudine (AZT) treatment for mother-baby pairs starting January 1994.
Main Results:
- Initial voluntary screening identified 1.4/1000 seropositive women; later universal screening identified 2.9/1000.
- Refusal rates decreased from 74 to 17 after implementing universal screening.
- Perinatal transmission decreased from 33% to 10% with AZT treatment.
Conclusions:
- Universal voluntary HIV screening with informed refusal achieves near 100% testing rates.
- Free AZT treatment significantly reduces vertical HIV transmission.
- This combined strategy is effective in controlling perinatal HIV transmission.
