Reported vs. Estimated VIH, SIDA Deaths in HASS, ( ) Of the 146,762 unique patients in HASS and according to information originally received from the report- 87% are diagnosed with HIV, 8% with AIDS, and 5% dead. Using estimated information (below), 68% are diagnosed with HIV, 19% with AIDS, and 13% are presumed dead. People are presumed dead if they were diagnosed prior to 2000 and do not have another report in HASS or they are 65 years or older and reported prior to People are presumed to have SIDA if they have a CD4 count <= 350 per ml blood. Note: These amounts may be subject to change as the methods for estimating death and out- migration are refined. Reported Estimated
Conclusion Since 2009, an estimation of 95% of all HIV cases diagnosed in Haiti have been reported to the case surveillance system. 252 sites (56%) are periodically reported HIV diagnosis cases. By early 2012, all four major electronic data sources were providing data feeds on a monthly basis. Crucial reporting variables are present in more than 99% of all case reports. Though the end of 2011, a total of 193,065 HIV cases were reported to HASS. Of those cases, 23.4% were reports related to a person reported more than once in the system. With the existing and use of the de-duplication algorithm 147,880 unique HIV cases are identified in the national HIV/AIDS case surveillance system
