Indiana Governor Mike Pence on Thursday declared a public health emergency in a rural Indiana county after 79 cases of HIV were confirmed there in the last several months. An outbreak of HIV may seem odd in such a remote part of the country. The dozens of confirmed cases, described as an epidemic, are centered in Scott County, about a half-hour north of Louisville with a population of about 25,000. But the spike has been fueled by growing heroin and drug use in rural counties like this one.
