US health experts are expressing a huge concern for what they are calling super-gonorrhoea.
The new superbug began its spread in Englands gay community but is quickly reaching the furthest corners of the globe.
Houston is being hit particularly hard, and the bug is no longer only affecting only the gay community.
The bug prompted worldwide attention last year when it became immune to its most widely used cure. US health experts are calling their attempts at stopping the bug a limited success and fear it may soon be completely untreatable.
The bug has been found to cause infertility, along with all the alements associated with regular gonorrhoea.
It is currently being treated with a combination of azithromycin and ceftriaxone, but resistance to azithromycin is spreading, and experts say its only a matter of time before ceftriaxone fails too.
Experts estimate there are at least 16,000 infected individuals in the Houston metropolitan area, and the number is growing daily.
Doctors are recommending that all sexually active people in the Houston area should refresh themselves on practicing safe-sex to help curb the spread of the bug. Englands senior health expert says the bug is frighteningly close to becoming untreatable.
Dr Gwenda Hughes, the head of the sexually transmitted infections unit at Public Health England, said: We cannot afford to be complacent.
She is encouraging people to practise safe sex to minimise the risk of sexually transmitted infections.
