There's been a rise in the number of people diagnosed with gonorrhea - particularly in Dublin.
New figures show young people and gay men are most at risk.
The HSE has set up an outbreak control team to monitor the situation.
Dr. Tom Kelly from the Everyman Centre says it's important to get regular STI tests, even if you're having safe sex.
He told 98FM News that "a lot of people think that if they have no symptoms, they have no sexually transmitted infections. Everyone is at risk of STIs and needs to get tested."
