GENEVA, Switzerland – The rise of superbugs, stoked by misuse of antibiotics and poor hospital hygiene, is enabling long-treatable diseases to once again become killers, the World Health Organization warned on Wednesday, April 30.
In a hard-hitting study of antimicrobial resistance – when bacteria adapt so that existing drugs no longer curb them – the UN health agency said the problem was a global emergency.
“Without urgent, coordinated action by many stakeholders, the world is headed for a post-antibiotic era, in which common infections and minor injuries which have been treatable for decades can once again kill,” warned Keiji Fukuda, the WHO’s assistant director-general for health security.
“Unless we take significant actions to improve efforts to prevent infections and also change how we produce, prescribe and use antibiotics, the world will lose more and more of these global public health goods and the implications will be devastating,” he said.
The unprecedented report gathered data from 114 countries, and focused on 7 different bacteria responsible for common, serious diseases such as diarrhea, pneumonia, urinary tract infections and gonorrhea.
Even so-called “last resort” antibiotics are losing their ability to fight such bacteria, with half of the patients showing resistance in some countries, the report said.
Medical charity Doctors Without Borders (MSF) said the scale of the crisis was frightening clear on the ground.
“We see horrendous rates of antibiotic resistance wherever we look in our field operations,” said Jennifer Cohn, an MSF medical director.
Spectre of E.Coli, gonorrhea
Among the report’s key findings were the global spread of resistance to carbapenem antibiotics – the last resort treatment for life-threatening infections caused by the common intestinal bacteria Klebsiella pneumoniae.
Known as K. pneumoniae, it is a major cause of hospital-acquired infections such as pneumonia and sepsis, often hitting newborns and intensive-care patients.
Resistance to one of the most widely used antibacterial medicines for the treatment of urinary tract infections caused by E. coli – fluoroquinolones, is also widespread.
There was hardly any resistance when the drugs were introduced in the 1980s, but it now affects half of patients in many part of the world, the WHO said.
The problem is a particular concern in Africa, the Americas, South and Southeast Asia, and the Middle East.
Resistance to third-generation cephalosporins – the last resort for tackling gonorrhea, which infects more than a million people every day – has been confirmed in Austria, Australia, Britain, Canada, France, Japan, Norway, South Africa, Slovenia and Sweden.
Another case in point is MRSA – methicillin-resistant Staphylococcus aureus – which has grabbed headlines due to a rash of outbreaks at hospitals.
Patients with MRSA are 64% more likely to die than those with a non-resistant form of the bug, the WHO said.
In parts of the Americas, resistance to MRSA treatment had reached 90%, while levels of 60%were seen in Europe, the study found.
‘Shot in the dark’
Resistance also raises health costs because of longer hospital stays and more intensive care.
Efforts to tackle the problem have lagged behind its growth, the WHO said, flagging weak or totally absent monitoring in many countries.
MSF’s Cohn echoed that.
“Countries need to improve their surveillance of antimicrobial resistance, as otherwise our actions are just a shot in the dark,” she said.
The WHO urged policymakers to raise their game by strengthening resistance tracking and laboratory capacity, and by regulating and promoting appropriate use of drugs.
They should also do more to stop infection in the first place, with better hygiene measures, access to clean water, infection control in health-care facilities, and vaccination, to reduce the need for antibiotics, it said.
Health workers and pharmacists should only prescribe antibiotics when truly needed, and the medical industry should step up efforts to ensure the sector stays ahead of emerging resistance, the WHO said.
Patients, meanwhile, should only use antibiotics when prescribed by a doctor, complete their treatment even if they feel better and not use leftover drugs, it added. – Rappler.com
