A new study by the non-profit Global Antibiotic Research and Development Partnership (GARDP) looked at access to antibiotics for nearly 1.5 million cases of carbapenem-resistant Gram-negative (CRGN) infections across eight major low- and middle-income countries, including India, Brazil and South Africa. CRGN bacteria are superbugs resistant to last-line antibiotics - yet only 6.9% of patients received appropriate treatment in the countries studied.India bore the lion's share of CRGN infections and treatment efforts, procuring 80% of the full courses of studied antibiotics but managing to treat only 7.8% of its estimated cases, the

in The Lancet Infectious Diseases journal reports. (A full drug course of antibiotics refers to the complete set of doses that a patient needs to take over a specific period to fully treat an infection.)Common in water, food, the environment and the human gut, Gram-negative bacteria cause infections such as urinary tract infections (UTIs), pneumonia and food poisoning.They can pose a serious threat to newborns and the elderly alike. Especially vulnerable are hospital patients with weakened immunity, often spreading rapidly in ICUs and proving difficult - and sometimes impossible - to treat. Treating carbapenem-resistant Gram-negative bacterial infections is doubly difficult because those bacteria are resistant to some of the most powerful antibiotics.

"These infections are a daily reality across all age groups," says Dr Abdul Ghafur, infectious disease consultant at Apollo Hospital in India's Chennai city. "We often see patients for whom no antibiotic works - and they die."The irony is cruel. While the world tries to curb antibiotic overuse, a parallel tragedy plays out quietly in poorer nations: people dying from treatable infections because the right drugs are out of reach.

"For years, the dominant narrative has been that antibiotics are being overused, but the stark reality is that many people with highly drug-resistant infections in low- and middle-income countries are not getting access to the antibiotics they need," says Dr Jennifer Cohn, GARDP's Global Access Director and senior author of the study.

The study examined eight intravenous drugs active against carbapenem-resistant bacteria - ranging from older antibiotics including Colistin to newer ones such as Ceftazidime-avibactam. Of the few available drugs, Tigecycline was the most widely used.He failed, because of resistance from the public and politicians, and was impeached, triggering this snap election to choose his successor.

But the chaos Yoon unleashed that night has festered.While stuck in limbo, without a president, the country has become more polarised and its politics more violent.

At street protests earlier this year it became commonplace to chant for various political leaders to be executed. And since launching his presidential bid, Lee has been receiving death threats, and his team say they have even uncovered a credible plot to assassinate him.This election is an opportunity to steer South Korea back onto safer, more stable ground, and heal these fractures.
