Abstract:
Early studies documented an inverse association between the HIV risk and duration of injection among injection drug users (IDUs). Results from subsequent studies have been inconsistent. To examine this issue, we conducted interviews with 395 street-recruited active IDUs from 38 neighborhoods in New York City during 2005 and 2008. We observed no significant differences in drug or risky sex behaviors by duration of drug use among these IDUs. Despite this, continuing to tailor HIV prevention programs for these recent-onset IDUs is prudent. The study's limitations are noted.

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.
