International private healthcare users should be among those targeted by sexual health campaigns.
The Terrence Higgins Trust has called for a more inclusive way to tackle sexually transmitted infections, including expanding sexual health campaigns to mature people and those coming out of long-term relationships.
"[We should] start looking across the whole of society not just certain [groups]," said Jason Warriner, clinical director of the charity.
"We know there are certain groups in society that are at a higher risk of HIV and sexually transmitted infections, but what we actually need to do is have a campaign that meets the needs of everybody, whether it is a young person or somebody in their 50s or 60s."
He urged anyone who has a new partner to have sexual health screening, as some infections may not cause symptoms but can affect fertility.
This in turn might lead to costly medical treatment further on down the line.
Mr Warriner's comments come after the Health Protection Agency revealed the number of people living with HIV in the UK reached an estimated 86,500 last year, but more than a quarter of these were unaware of their condition.
