A 'super' strain of untreatable gonorrhea is sweeping developed countries across the world including Britain and Northern Ireland.
The sexually transmitted disease, which infects millions of people every year, is becoming resistant to all antibiotics, according to the World Health Organisation.
The U.N. health agency is urging governments and doctors to step up surveillance of the STD, the second most common after chlamydia.

Gonorrhea can cause inflammation, infertility, pregnancy complications and, in extreme cases, lead to maternal death.
Babies born to mothers with gonorrhea have a 50 per cent chance of developing eye infections that can result in blindness.
'This organism has basically been
developing resistance against every medication we've thrown at it,' said
Dr Manjula Lusti-Narasimhan, a scientist in WHO's department of STDs.
This includes a group of antibiotics called cephalosporins currently considered the last line of treatment.
Resistance to cephalosporins was first
reported in Japan, but more recently has also been detected in Britain,
Australia, France, Sweden and Norway.
As these are all countries with
well-developed health systems, it is likely that cephalosporin-resistant
strains are also circulating undetected elsewhere.
More than 17,000 new cases of gonorrhea were reported in the UK in 2009. Young men and women are affected most – the highest rates of gonorrhea are seen in women aged 16-19 and men aged 20-24.
think this is probably only the tip of the iceberg,' said Professor
Catherine Ison, who oversees the national surveillance program for
treatment of resistant gonorrhea in England and Wales.

Doctors have blamed overuse or misuse of antibiotics for the disease moving towards becoming a superbug, coupled with the bacteria's astonishing ability to adapt.
Professor Ison said doctors in Britain are now switching to
using a combination of antibiotics over a longer period of time to
combat resistant gonorrhea.
Dr Lusti-Narasimhan said that better sex education was needed,
as proper condom use is an effective means of stopping transmission.
'We're not going to be able to get rid of it completely,' she said in an interview ahead of WHO's public announcement on its 'global action plan' to combat the disease. 'But we can limit the spread.

'In a couple of years it will have become resistant to every treatment option we have available now.'
Dr Lusti-Narasimhan said the new guidance is aimed at ending complacency about gonorrhea and encouraging researchers to speed up their hunt for a new cure.
Once considered a scourge of sailors and soldiers, gonorrhea – known colloquially as the clap – became easily treatable with the discovery of penicillin.
Now, the global health body estimates that gonorrhea is responsible for 106million infections annually.
It also increases the chances of infection with other diseases, such as HIV.
'It's not a European problem or an African problem, it's really a worldwide problem,' said Dr Lusti-Narasimhan.
These bacteria survive antibiotic treatment due to a mutation that makes them resistant, then quickly spread their genes in an accelerated process of natural selection.
This is a general problem affecting all antibiotics, but gonorrhea is particularly quick to adapt because it is good at picking up snippets of DNA from other bacteria, said Dr Lusti-Narasimhan.
'If it didn't do so much damage it would actually be a fun organism to study,' she said.
The over-the-counter availability of low potency antibiotics in some Asian countries is another reason resistance is increasing, she said.
The Geneva-based WHO wants countries not just to tighten their rules for antibiotic use but also to improve their surveillance systems so that the full extent of the problem can be determined.
