Measuring incidence

Here is a poster on measuring incidence in Asia. It was presented in DC. Without measuring the incidence or new infection rate, there is no way to know whether Myanmar (or any country) will achieve the Millennium Development Goals or the Asean Declaration of Commitment.

Background: Rates of new HIV infections in Asia are poorly characterized, likely resulting in knowledge gaps about infection trends and the most important areas to target for interventions. Incidence data are needed to better characterize the HIV/AIDS epidemic in Asia, inform prevention planning and prioritize resources.

Methods: We conducted a systematic review of peer-reviewed English language publications and conference proceedings on HIV incidence in thirteen countries - Bangladesh, Cambodia, China, India, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Taiwan, Thailand, and Vietnam - from 1985 to 2010. Data on HIV incidence rate, incidence estimation method and risk factors for incident infection were extracted.

Results: The search yielded 56 published articles and 38 conference abstracts for seven countries. There were 304 unique HIV incidence estimates reported over the past 25 years. 124 (41%) were obtained from prospective cohort studies, 99 (33%) from antibody-based tests for recent infection, 31 (10%) from retrospective cohort studies and 28 (9%) from other cross-sectional studies. High HIV incidence rates were observed among commercial sex workers (0.4 to 27.8 per 100 person-years), injection drug users (0.0 to 43.6 per 100 person-years), men who have sex with men (0.7 to 15.0 per 100 person-years), and sexually transmitted infection clinic attendees (0.2 to 19.9 per 100 person-years). Risk factors for incident HIV infection included brothel-based sex work and cervicitis among commercial sex workers; young age, frequent injection use and sharing needles or syringes among injection drug users; multiple male sexual partners, receptive anal intercourse and syphilis infection among men who have sex with men.

Conclusions: HIV Incidence data are limited in Asia. In the few countries with available data, incidence rates were highest in high-risk populations and varied widely by incidence estimation method. Established surveillance systems that routinely monitor trends in HIV incidence are needed to improve the HIV response in Asia.
