Gonorrhoea can be spread through kissing, a leading expert has claimed, amid calls for guidelines over sexually transmitted infections to be updated to reflect the latest research.
For decades, scientists have insisted that this STD, which has been referred to as "the clap" since the 1500s, could not be transmitted through snogging but a new study appears to show otherwise.
In January, a team of researchers in Australia reviewed six studies that looked at whether tongue kissing was a risk factor for gonorrhoea and chlamydia.
