YOUNG Tasmanians continue to catch sexually transmitted infections, with more than 1800 cases of chlamydia reported last year.
State health data also indicated that women account for 70 per cent of reported cases of chlamydia, with young men failing to take sexual health checks.
Public health senior medical advisor Dr Mark Veitch said despite a slight decrease in chlamydia since 2010, it still remained an important health issue for young Tasmanians.
"Notifications mainly involve older teenagers and young adults," Dr Veitch said.
"In recent years, three quarters of cases were aged from 15 to 24 years.
"Screening is more common among young women."
Dr Veitch said infections such as syphilis and gonorrhoea accounted for up to 30 cases a year.
"It is important to remember that unprotected sexual contact may also put people at risk of other STIs, such as herpes, and non-infectious consequences, such as unplanned pregnancy," he said.
Sexual health checks can be provided by GPs, Family Planning Tasmania and the Sexual Health Service.
Family Planning Tasmania posts free condoms to those who text their full name, address and age to mobile number 0488492443.
