The Iowa Department of Public Health says the number of people diagnosed with HIV in Iowa has risen in the last year. Statistics for 2016 shows Iowa experienced the largest number of HIV cases since 1989 with 136. People aged 25 through 44 years continue to make up the largest segment of those diagnosed with the disease. The number of young adults 15 through 24-years-old diagnosed with HIV fell from an all-time high of 33 in 2015 to 28 cases last year. The health department also says statistics indicate those at risk for HIV are getting more timely access to testing.
