Comparing Two Studies on estimated HIV Incidence and Prevalence Introduction In the era of HIV global pandemic, estimating incidence and prevalence correctly is critical, as it becomes a strong tool for authorities to decide next action, to mitigate infection rate and its multiple consequences to society. 2 studies investigated HIV estimated incidence from different approaches. Prejean et al studied the incidence estimates in the United States, by using a four-year data obtained from HIV incidence surveillance from 16 states and 2 cities, and expanded the estimated incidence to other areas in the United States1; they used a ratio of group-specific incidence at a measured area to new AIDS diagnosis, to AIDS diagnosis in other areas1. On the other hand, Walker et al estimated prevalence by applying two strategies; using HIV prevalence of pregnant women for countries suffering general epidemics, and using HIV prevalence in high-risk groups for countries with localized epidemic to estimate HIV prevalence .2 After obtaining prevalence, they estimated prevalence u sing ratio of number screened against the specific group in that country against the adult population, and estimated incidence according to estimates on how long a person with HIV can survive and vertical transmission in the area with estimated national prevalence2. While both studies are carefully planned, some aspects pose assumptions and asks the reader the potential direction of bias. A.

Two studies were commissioned: a targeted systematic evidence review of six selected questions relating to the benefits and harms of screening; and a decision analysis that used population modeling techniques to compare expected health outcomes, starting and ending screening at different ages, and also comparing annual versus biennial screening (â€Å"Screening for Breast Cancer† 2009).

Women and children bear a disproportionate share of the burden, and in many settings continue to experience high rates of new HIV infections and of HIV-related illness and death. In 2005 alone, an estimated 540 000 children were newly infected with HIV, with about 90% of these infections occurring in sub-Saharan Africa (UNAIDS, 2006) .UNAIDS estimates that approximatelyRead MoreHiv/Aids South Africa5278 Words   |  22 PagesThe HIV/AIDS Epidemic In South Africa Acquired Immune Deficiency Syndrome (AIDS) caused by the Human Immunodeficiency Virus (HIV) is one of many infectious diseases that plague the world today.
