The HIV incidence in Viet Nam has shown a continuous and notable decrease from 2013 to 2023, moving from 0.21 to 0.07 per unit of uninfected population aged 15-49. This represents a sharp decline, with a significant year-on-year percentage variation averaging at around -10% per year, and a Compound Annual Growth Rate (CAGR) of -10.22% over the last five years. Historically, from 2013 to 2023, various government interventions and health campaigns have likely contributed to this downward trend.

Future projections from 2024 to 2028 indicate a continued but slowing decline in HIV incidence, with a forecasted 5-year CAGR of -6.51% and an overall reduction of 28.57% by 2028. Key trends to watch include:

Further implementation and effectiveness of preventive measures and educational programs.
Access to healthcare services, particularly for high-risk groups.
Impact of new medical treatments and technologies in reducing HIV transmission rates.
