| [Abstract]?Objective To analyze epidemiological characteristics of HIV-infected pregnant women in Shenzhen and to provide policy formulation for the prevention of mother-to-child transmission of HIV in areas with large float populations. Methods?The demographic and clinical data of 49 pregnant women who received HIV mother-to-child transmission block management in Shenzhen Third People's Hospital from January 1, 2019, to December 31, 2021, were collected and analyzed. Results?Forty-nine HIV-infected pregnant women were involved, the average age was (25.90±5.18) years old, 89.8% (44/49) were below college level, 59.2% (29/49) are registered residents, and 40.8% (20/49) are non-registered residents or floating population. HIV infection was mainly found in passive diagnosis, accounting for about 75.5% (37/49), and HIV infection was found in active diagnosis, accounting for about 24.5% (12/49). 38.8% (19/49) were transmitted through sexual contact, and 59.2% (29/49) by an unknown route of transmission. All 49 HIV-infected women received ART after delivery. 93.9% (46/49) of their spouses or sexual partners were tested for HIV and 32.6% (15/46) were diagnosed with HIV infection. All of their children were given blocking drugs within 6 hours after birth, early diagnosis, and artificial feeding. 6.1% (3/49) of children were born with high-risk HIV exposure. Conclusions?The low rate of early diagnosis in HIV-infected pregnant women leads to a higher risk of exposure for their infants. Strengthening health education and management of HIV-infected pregnant women is an important part of solving the problem of mother-to-child transmission of HIV. |
