Approximately how many people were living with HIV in the U.S. in 2016?

• A. Approximately 1.1 Million.
• B. Approximately 2.0 Million.
• C. Approximately 500 Thousand.
• D. Approximately 100 Thousand.

Answer: (A)

Understanding how many people live with HIV in a given year is about prevalence—the total number currently infected, including both those who know their status and those who don’t. In 2016, the CDC estimated about 1.1 million people in the United States were living with HIV, which is the best figure for that year. This count reflects infections present at that time, not just new cases. For context, new HIV infections in 2016 were roughly around 39,000, illustrating the difference between total living cases and new diagnoses. The other options would imply far more or far fewer people than the best available estimate, so they don’t fit the actual prevalence data for that year.
