New study looks at the scale of STI cases in Ireland.
New figures reveal STI cases in the midlands have outnumbered the winter vomiting bug and flu in recent years.
A HSE study found there were nearly two and a half thousand cases of chlamydia in the mid-west region between 2013 and 2017.
But there were just over fifteen-hundred flu cases and almost 550 norovirus infections.
Chlamydia topped the list of serious infections in counties Clare, Limerick and Tipperary almost every year in the study.
It was only in Limerick that genital warts cases were more prevalent than flu.
