Components of the Surveillance Program

The primary components of the Surveillance Program are:

Active Case Ascertainment

Field epidemiologists conduct active case surveillance in all geographic regions in Louisiana.

Reporting sites include a broad spectrum of health care facilities (inpatient and outpatient, public, private and federal), hospitals (within hospitals - ICP, medical records, social services, pharmacy, labs), other in-patient facilities (extended care facilities, hospices, nursing homes), STD/HIV clinics, physician offices, other medical clinics, laboratories, blood and plasma centers, home health agencies, chemical dependency facilities, psychiatric units and correctional facilities.

Field epidemiologists are in routine contact with all reporting sites to help ensure complete reporting.

Laboratory Surveillance

The Laboratory Surveillance program maintains active reporting from laboratories, a critical part of case ascertainment.

Since 1993-1994, when surveillance systems were revised to accommodate HIV (non-AIDS) reporting and the immunologic criteria of the new AIDS case definition, laboratories have been an important source of surveillance data for HIV infection. Additionally, evaluation studies have shown laboratory reporting to be efficient and timely.

In 1999, Louisiana's Sanitary Code was revised to make reportable all HIV/AIDS-related tests (CD4 counts and viral loads). To accommodate the high volume of incoming laboratory data, this program has developed computer-based electronic reporting as well as a more expansive data management system to accommodate the incoming data.

The STD/HIV Program coordinates with other OPH programs in the reporting system of other reportable conditions including STDs, tuberculosis and emerging pathogens.

Perinatal Surveillance

The Perinatal Surveillance Program monitors perinatal transmission rates, counseling and testing, and prenatal care among HIV- and syphilis-infected women and treatment issues of the women and their infants.

A data abstraction form is completed for all children born to women with HIV or syphilis infection reported to OPH. The babies exposed to HIV are followed at six-month intervals to determine their HIV status and, if infected, follow their course of treatment.

HIV Incidence Surveillance

Incidence Surveillance was established in late 2004 in Louisiana to identify and study new HIV infections. While the HIV Surveillance Program has traditionally compiled, analyzed, and distributed information about persons who test positive for HIV, there are many people thought to be infected with HIV who have never been tested. Incidence Surveillance collects information about persons who test positive and are found likely to have been infected with HIV in the last year and uses this information to calculate the number of all persons, diagnosed and non-diagnosed, with HIV. By identifying and characterizing persons most recently infected with HIV, Incidence Surveillance enables the public health community to focus on the leading edge of the HIV epidemic, helping to improve targeted prevention efforts.
