Approximately how many new HIV infections occur each year in the United States?

Explanation:
Understanding annual HIV incidence in the United States. This tells you how many people newly acquire HIV in a given year, not how many people are living with HIV at any one time. The best current estimate is about 38,000 new infections per year, based on CDC surveillance data. That means roughly 100 new infections each day, or about four per hour, though yearly numbers can vary a bit. This level fits what we know from ongoing monitoring, whereas about 10,000 would be far too low and 100,000 or 250,000 would be far too high given the observed data. So the approximate answer is around 38,000.
