HIV/AIDS emerged as one of the most important public health issues of the late twentieth and early twenty-first centuries and is now one of the leading causes of global morbidity and mortality. The HIV/AIDS epidemic has prompted wide reaching changes in public health, clinical practice, and scientific research, and had a great impact upon societies throughout the world. The global prevalence of HIV infection (percentage of persons infected with HIV) is remaining at the same level, although the global number of persons living with HIV is increasing owing to the ongoing accumulation of new infections with longer survival times.
