The number of whooping cough cases appears to be on the rise in South Dakota.
So far this year there have been 19 diagnosed cases in the state. That compares to a five-year average of seven cases for this time of year.
Nationwide there has been an increase in whooping cough cases. Health officials say the outbreak is because of an increasing number of children not getting vaccinated against the potentially deadly bacteria.
The latest report released from the South Dakota Department of Health also shows an increase in several sexually transmitted infections.
The number of HIV cases so far this year is up 200 percent from the five-year average.
15 South Dakotans have been diagnosed this year.
Syphilis cases are also up. 28 people in the state have been diagnosed with outbreaks in Minnehaha County and the north-central counties.
