What is HIV Incidence SurveillanceWhat is HIV Incidence Surveillance
(HIS)?(HIS)?
HIV incidence measures the number of new HIV
infections in a population over a period of time.
HIS estimates are based on data collected through
routine case reporting and a newly developed
biomarker.
HIS is part of a national effort supported by the
Centers for Disease Control and Prevention
(CDC) to fully integrate incidence as a component
of the HIV/AIDS surveillance system and will
help target HIV treatment and prevention efforts.

Editor's Notes

  1. The goals of routine HIV screening are two-fold: improve the quality of life and survival of patients who have HIV infection and decrease the risk of transmission of infection to others. Prompt referral of HIV-infected individuals to HIV care is a critical step in this process. In an effort to increase the likelihood that a person living with HIV infection can benefit from treatment and care plus reduce the chance of spreading the infection to others, CDC, through their revised recommendations, seeks to increase the number of physicians offering routine HIV screening as a standard part of care.
  2. The tile of this presentation is phrase taken from a research study into the impact of stigma conducted by the Panos institute. The phrase Dirty Blood and Worms from the gutter illustrates how language is used to stigmatize people with HIV/AIDS
  3. Then concept has origins in the ancient Greek world. The modern usage draws on the work of Irving Goffman an American sociologist, who developed the concept in relation to his work on mental illness. Stigma builds on and reinforces negative stereotypes. In HIV/AIDS the stigma of the disease emerges from several sources; the fear of plague and epidemic disease, the taboo’s associated with the way the disease is transmitted; the association with death and dying. Certain groups have come to be identified with HIV/AIDS. In the early western epidemic and still in many counties it is seen as a disease of homosexual men. It has also been seen as an African disease and given encouragement to racist views on Africans. In Asia it is mainly associated with sex work and drug use and people identified with these groups bear a double and sometimes triple stigma.
  4. Research into the causes and effects of stigma will reveal what underlying assumptions are driving stigma. Religious groups play an important role in assisting communities and PLWHA to address the beliefs and values that underpin stigma GIPA Positive speakers operate in many countries in the Asia region. Media are also key players, encouraging a more positive approach and representation of PLWHA by the media is an important aspect of changing discriminatory attitudes Involving PLWHA in the response is perhaps the most important aspect of addressing stigma. There are still too few examples of PLWHA who are active.
