AIDS cases with no identified risk: artifact or reality? The Connecticut example
Abstract:
Connecticut's 66 AIDS cases initially reported with no identified risks (NIRS) were reviewed and intensively investigated. Investigation resulted in reclassification of 45 cases (68.2%) to categories of known risk; one case (1.5%) was misdiagnosed as AIDS. Twenty cases (30.3%) remain NIRS because no risk could be established at this time. Evidence that NIRS represent reporting artifact, rather than unknown or new modes of transmission, was found. (1) NIRS are cases for which information on sexual behavior is highly sensitive or difficult to obtain. After investigation, 72% of reclassified Connecticut NIRS were determined to have risks related to sexual transmission. (2) The percentage of NIRS fluctuates according to reporting source and method of investigation. Within Connecticut, major reporting sources vary from a high of 15% to a low of 0% NIRS among their cases. The most effective method for establishing risks was to obtain information from reporting sources.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
