PEOPLE are being reminded to ensure they have safe sex and get screening advice in order to reduce the risk of getting an infection.
Figures released by Public Health England show 3,547 people were diagnosed with chlamydia in Hampshire in 2012, and 1,196 in Portsmouth.
Hampshire County Council is highlighting the importance of safe sex.
Councillor Liz Fairhurst, who is in charge of health and wellbeing at the county council, said: ‘Left untreated, sexually-transmitted infections can lead to complications including ectopic pregnancy, infertility, disability, cancer and premature death.
‘As part of our new public health responsibilities, the council commissions programmes and services that support people to develop and maintain good sexual health.
‘Getting screened for HIV and STIs can lead to early diagnosis and treatment, as often these infections have no symptoms.’
