While there’s a big focus on the H1N1 flu at the moment, the state health department is releasing a report on all of last year’s reported diseases. The division of the Iowa Department of Public Health that tracks infectious diseases logged nearly 50,000 total cases during all of last year.

Close tracking lets health officials spot trends and outbreaks. Hepatitis-A cases saw the biggest increase last year, with 109 cases reported, an increase of nearly 300% over the three-year average. There were 108 new HIV cases reported, down from 128 the previous year.

For sexually-transmitted diseases, chlamydia cases rose 15%, while gonorrhea cases fell. Among the rare diseases, Iowa had one case of leprosy reported last year in an immigrant from Micronesia.
