The Indiana State Department of Health marks April as the annual observance of Sexually Transmitted Diseases (STDs) Awareness Month. The ISDH is encouraging Hoosiers to discuss prevention and know their risks. STD Awareness Month is an annual observance to take notice of the impact of STDs and to promote testing. It’s also an opportunity for individuals, doctors and community-based organizations to address ways to prevent the nearly 20 million occurrences of STDs nationally from getting higher. Half of all new sexually transmitted infections that occur each year are among youths. These numbers highlight an urgent need for prevention. Preliminary data indicates 29,086 cases of chlamydia, 7,910 cases of gonorrhea and 298 cases of primary and secondary syphilis were reported in Indiana in 2015.
