The research published in The Lancet shows how the team used molecular typing or genetic fingerprinting to identify the gonorrhoea strains infecting individuals in London. They found the typing identified a number of common strains which appear to identify individuals in the major sexual networks in London.

Professor Brian Spratt, from Imperial College London, and senior author of the paper said: "Gonorrhoea is a good indicator of unsafe sex but most infections don't spread much and most strains in London are only found in one or a few individuals.
