LONDON, March 11 (Reuters) - Antibiotic resistance poses a catastrophic threat to medicine and could mean patients having minor surgery risk dying from infections that can no longer be treated, Britain's top health official said on Monday.
Sally Davies, the chief medical officer for England, said global action is needed to fight antibiotic, or antimicrobial, resistance and fill a drug "discovery void" by researching and developing new medicines to treat emerging, mutating infections.
Only a handful of new antibiotics have been developed and brought to market in the past few decades, and it is a race against time to find more, as bacterial infections increasingly evolve into "superbugs" resistant to existing drugs.
"Antimicrobial resistance poses a catastrophic threat. If we don't act now, any one of us could go into hospital in 20 years for minor surgery and die because of an ordinary infection that can't be treated by antibiotics," Davies told reporters as she published a report on infectious disease.
"And routine operations like hip replacements or organ transplants could be deadly because of the risk of infection."
One of the best known superbugs, MRSA, is alone estimated to kill around 19,000 people every year in the United States - far more than HIV and AIDS - and a similar number in Europe.
And others are spreading. Cases of totally drug resistant tuberculosis have appeared in recent years and a new wave of "super superbugs" with a mutation called NDM 1, which first emerged in India, has now turned up all over the world, from Britain to New Zealand.
