What does IVDU stand for in the context of HIV transmission?

IVDU stands for Intravenous Drug Use in the context of HIV transmission. This term is significant because individuals who use drugs intravenously often share needles or other injection equipment, leading to a higher risk of transmitting HIV and other blood-borne infections. Understanding the routes of transmission, such as intravenous drug use, is essential for effective education on prevention strategies.

The other terms listed do not accurately represent the acronym IVDU within the context of HIV transmission. Intraoral viral disease use, Indigenous viral drug use, and Intermittent viral drug use are not recognized medical or public health terms related to HIV transmission. Therefore, focusing on intravenous drug use is crucial for understanding one of the major risk factors in the spread of HIV.
