title: [A study on the effectiveness of prevention of mother-to-child HIV, syphilis, and hepatitis B transmission among pregnant women in Dehong prefecture,Yunnan province, China from 2011 to 2013].
abstract: OBJECTIVE
  To demonstrate the effectiveness of prevention of mother-to-child HIV, syphilis, and hepatitis B transmission among pregnant women in Dehong prefecture, Yunnan province, China from 2011 to 2013.
  
  
  METHODS
  Data were collected mainly from the continuous HIV surveillance system and prevention of mother-to-child transmission (PMTCT) reporting system of Dehong prefecture, and supplemented by annual reported data on HIV, syphilis, and hepatitis B PMTCT to know the general demographic characteristics, HIV testing and counseling service, PMTCT service, and other medical services. Data were presented as absolute numbers and proportions.
  
  
  RESULTS
  From 2011 to 2013, the number of pregnant women participating in HIV, syphilis, and hepatitis B testing in Dehong prefecture increased and the HIV testing rates were 99.2% (18 694/18 854), 99.9% (22 047/22 060) and 99.9% (21 751/21 756), the syphilis testing rates were 56.0% (10 550/18 854), 99.6% (21 980/22 060) and 99.9% (21 751/21 756), and the hepatitis B testing rates were 60.2% (11 358/18 854), 99.6% (21 974/22 060) and 99.9% (21 751/21 756). From 2011 to 2013, the HIV positive rates were 0.87% (327/37 787),0.82% (319/38 817) and 0.85% (315/37 261), the syphilis positive rates were 0.05% (10/18 520),0.12% (43/36 817) and 0.11% (40/35 888), the hepatitis B positive rates were 2.46% (456/18 520), 2.23% (794/35 547) and 2.14% (739/34 468), respectively. The rates of HIV-positive pregnant women giving birth in hospitals were 99.2% (128/129), 100.0% (141/141) and 100.0% (141/141). From 2011 to 2013, the proportions of HIV-positive pregnant women receiving antiretroviral therapy were 99.2% (128/129), 99.3% (140/141) and 99.3% (140/141), respectively. And the treatment rate of syphilis-positive pregnant women were 71% (5/7), 89% (16/18) and 97% (32/33). The rates of hepatitis B immunoglobulin injection among new-borns of hepatitis B-positive pregnant women were 92.9% (263/283), 99.7% (612/614) and 99.4% (629/633). The estimated rates of mother-to-child transmission of HIV were 2.28%, 2.30% and 3.00%, respectively.
  
  
  CONCLUSIONS
  There was an increasing trend of HIV, syphilis, and hepatitis B testing rate and the positive rate kept at a low level. The proportions of HIV-positive pregnant women receiving HIV, syphilis, and hepatitis B PMTCT services increased annually, while the proportion of HIV MTCT kept at an overall low level from 2011 to 2013, which indicated its effectiveness of HIV PMTCT work during recent years in Dehong prefecture,Yunnan province, China.
