  2. Background • Information on epidemiological characteristics of epidemic is essential to develop strategies, programmes and activities to combat HIV epidemic in a country. • To provide evidence based information for intervention 2009 Botswana ante-natal sentinel surveillance aimed to study epidemiological features of transmission of HIV infection among pregnant women

  3. Objectives: • To determine prevalence of HIV infection among pregnant women as marital status • To determine prevalence of HIV infection among pregnant women as occupation • To determine proportion of number of pregnancies as HIV seroprevalence status • To determine seroconversion over time among pregnant women prevalence of HIV infection among pregnant women as marital status • To monitor trends of HIV infection among pregnant women of 15-49 years old over time, and across sites. • To use left over blood for routine tests during ANC visits to determine HIV prevalence, and HIV incidence. 3

  4. Methodology • Survey Design an anonymous, unlinked, cross-sectional survey. • Study population Pregnant women aged 15 to 49 years attending public health facilities • Facilities participated In all 24 districts of the country 262 facilities • Data collection period 13 July 2009 – 9 October 2009

  5. Socio-demographic health status variables used in survey • Age of participant (years) • Marital status • Gravidity (number of pregnancies) • Educational level of participant (grade 0-University) • Employment status • Main occupation • Previous HIV status • HAART status

  6. Data Analysis • Valid forms 7339 were analyzed usingMicrosoft Excel andEpi Info version 3.5.1 statistical software

  7. Sociodemographic status of the participants • 73% were below 30 years of age, • 80% were single mother, 7% co-habiting • 37% had 3 or more number of pregnancy • 20% domestic helper followed by 13% professionals • 58% (1383/2399) among total tested positive were known earlier positive • 3713 (out of 7339) were known negative before the current pregnancy

  8. Married had lowest prevalence and living together highest through out 2000-2009

  9. 40 years and above are small in umber. Therefore not included here.

  10. Earlier all were tested negative

  11. CONCLUSIONS • Co-inhibiting women and single women are at high risk of getting HIV infection in compare to married women. • HIV positive women may be considered as high risk group for transmission of HIV infection as they have more number of pregnancy in compare to women who are HIV negative or unknown to HIV status. • A large number of HIV positive pregnant female are unaware of their HIV status

  12. Recommendations • In addition, sociological study would provide in put to understand better the high transmission rate among some sub population. • To study risk factors for high prevalence rate among co-inhibiting women. • Encourage people who practice unsafe sex for voluntary testing

  13. Thanks Thanks
