Oral sex is causing the spread of a dangerous gonorrhoea superbug, experts have warned.
The untreatable strain of gonorrhoea is rapidly spreading across the world putting millions of lives at risk, the World Health Organisation has warned.
Experts said that incurable gonorrhoea has started to spread after becoming resistant to antibiotics, which has been partly caused by oral sex and a decline in condom use.
The sexually transmitted bacteria can live at the back of the throat and, because of this, has been evolve immunity to antibiotics used to treat common throat infections.
The WHO issued a warning after it confirmed that three people had contracted the superbug.
