Impact of the 1993 CDC surveillance definition of AIDS in Texas, 1991-1994

Texas Medicine

Abstract

In 1993, the Centers for Disease Control and Prevention (CDC) expanded the surveillance case definition of AIDS to include all individuals showing immune suppression, measured by absolute CD4 lymphocyte count or CD4/CD8 ratio, as well as those presenting with the 23 clinical conditions from previous case definitions or with three new indicator conditions (pulmonary tuberculosis, recurrent pneumonia, and invasive cervical cancer). The greatest impact of the expanded definition is the dramatic increase in cases reported in 1993, largely due to a backlog of 1992-diagnosed cases that meet the new criteria. Texas reported a 136% increase in cases in 1993 compared with 1992. Despite a drop between 1993 and 1994, the number of reported cases increased 75% overall between 1992 and 1994. Most cases reported in 1993 and 1994 fall under the 1993 expanded surveillance case definition (59% and 60%, respectively). More than 90% of all cases reported under the new definition are classified under immunologic criteria. The Department of Health and Human Services (DHHS) Public Health Region 4 was the most affected, with a 213% increase in reported cases between 1992 and 1993, and a 163% increase between years 1992 and 1994. In Texas, the new def...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
