The obstetric face and challenge of HIV/AIDS.

摘要

The human immunodeficiency virus (HIV) pandemic is one of the most serious health crises facing the world. Of the estimated 33.2 million people living with HIV worldwide, 22.5 million (68%) live in Sub-Saharan Africa, where women of childbearing age are most severely affected. Children primarily acquire HIV infection through mother-to-child transmission. Despite recent encouraging success, low-income countries have not been able to effectively curtail transmission of HIV to the infant during or after pregnancy, resulting in about 90% of the estimated 420,000 newly infected children per annum occurring in Sub-Saharan Africa.
