The WHO yesterday sounded the alarm over soaring numbers of drug-resistant bacterial infections, compromising the effectiveness of life-saving treatments, and rendering minor injuries and common infections potentially deadly.
The UN health agency warned that one in six laboratory-confirmed bacterial infections worldwide in 2023 showed resistance to antibiotic treatments.
“These findings are deeply concerning,” Yvan J-F. Hutin, head of the WHO’s antimicrobial resistance department, told reporters. “As antibiotic resistance continues to rise, we’re running out of treatment options and we’re putting lives at risk.”

Bacteria have long developed resistance against medicines designed to fight them, rendering many drugs useless.
This has been accelerated by the massive use of antibiotics to treat humans, animals and food.
Antimicrobial-resistant (AMR) superbugs directly cause more than 1 million deaths and contribute to nearly 5 million deaths every year, the WHO said.
In a report on AMR surveillance, the WHO examined resistance prevalence estimates across 22 antibiotics used to treat infections of the urinary and gastrointestinal tracts, the bloodstream and those used to treat gonorrhea.
In the five years leading to up 2023, antibiotic resistance increased in more than 40 percent of the monitored antibiotics, with an average annual rise of between 5 and 15 percent, the report found.
For urinary tract infections, resistance to antibiotics was typically higher than 30 percent globally, it showed.
The report looked at eight common bacteria pathogens, including Escherichia coli and Klebsiella pneumoniae, which can lead to severe bloodstream infections that frequently result in sepsis, organ failure and death.
The WHO warned that more than 40 percent of E coli infections and 55 percent of K pneumoniae infections globally are now resistant to third-generation cephalosporins — the first-choice treatment for these infections.
“Antimicrobial resistance is outpacing advances in modern medicine, threatening the health of families,” WHO Director-General Tedros Adhanom Ghebreyesus said in a statement.
The WHO hailed improvements in surveillance, but warned that 48 percent of nations were still not reporting any AMR data.
“We are definitely flying blind in a number of countries and regions that have insufficient surveillance systems for antimicrobial resistance,” Hutin said.
Judging from the available data, most resistance was found in places with weaker health systems and less surveillance, the WHO said.
The highest resistance was found in the Southeast Asian and eastern Mediterranean regions, where one in three reported infections were resistant.
In Africa, one in five infections was resistant.
Silvia Bertagnolio, who heads the WHO unit for antimicrobial resistance surveillance, told reporters that it was unsurprising that resistance would be higher in places with weaker health systems, since they might lack the capacity to diagnose or treat pathogens effectively.
The WHO has warned that there are not enough new tests and treatments in the pipeline to tackle the spread of drug-resistant bacteria.
This is creating a significant “future threat,” Hutin said.
“The increasing antibiotic use, the increasing resistance and the reduction of the pipeline is a very dangerous combination,” he said.
FRUSTRATIONS: One in seven youths in China and Indonesia are unemployed, and many in the region are stuck in low-productivity jobs, the World Bank said Young people across Asia are struggling to find good jobs, with many stuck in low-productivity work that the World Bank said could strain social stability as frustrations fuel a global wave of youth-led protests. The bank highlighted a persistent gap between younger and more experienced workers across several Asian economies in a regional economic update released yesterday, noting that one in seven young people in China and Indonesia are unemployed. The share of people now vulnerable to falling into poverty is now larger than the middle class in most countries, it said. “The employment rate is generally high, but the young struggle to
STEPPING UP: Diminished US polar science presence mean opportunities for the UK and other countries, although China or Russia might also fill that gap, a researcher said The UK’s flagship polar research vessel is to head to Antarctica next week to help advance dozens of climate change-linked science projects, as Western nations spearhead studies there while the US withdraws. The RRS Sir David Attenborough, a state-of-the-art ship named after the renowned British naturalist, would aid research on everything from “hunting underwater tsunamis” to tracking glacier melt and whale populations. Operated by the British Antarctic Survey (BAS), the country’s polar research institute, the 15,000-tonne icebreaker — boasting a helipad, and various laboratories and gadgetry — is pivotal to the UK’s efforts to assess climate change’s impact there. “The saying goes
ENERGY SHIFT: A report by Ember suggests it is possible for the world to wean off polluting sources of power, such as coal and gas, even as demand for electricity surges Worldwide solar and wind power generation has outpaced electricity demand this year, and for the first time on record, renewable energies combined generated more power than coal, a new analysis said. Global solar generation grew by a record 31 percent in the first half of the year, while wind generation grew 7.7 percent, according to the report by the energy think tank Ember, which was released after midnight yesterday. Solar and wind generation combined grew by more than 400 terawatt hours, which was more than the increase in overall global demand during the same period, it said. The findings suggest it is
TICKING CLOCK: A path to a budget agreement was still possible, the president’s office said, as a debate on reversing an increase of the pension age carries on French President Emmanuel Macron yesterday was racing to find a new prime minister within a two-day deadline after the resignation of outgoing French Prime Minister Sebastien Lecornu tipped the country deeper into political crisis. The presidency late on Wednesday said that Macron would name a new prime minister within 48 hours, indicating that the appointment would come by this evening at the latest. Lecornu told French television in an interview that he expected a new prime minister to be named — rather than early legislative elections or Macron’s resignation — to resolve the crisis. The developments were the latest twists in three tumultuous
