Antibiotic access crisis fuels spread of superbugs in poorer countries
Less than 7% of people with severe drug-resistant infections in low- and middle-income countries are receiving the antibiotics they need, according to a new study that warns the shortfall is fuelling deaths and driving the spread of antimicrobial resistance (AMR).
The research, published in "The Lancet Infectious Diseases", estimates nearly 1.5 million infections caused by carbapenem-resistant Gram-negative (CRGN) bacteria occurred across eight countries in 2019, resulting in almost 480,000 deaths.
Yet, just under 104,000 appropriate antibiotic courses were distributed, covering only 6.9% of cases on average—ranging from as low as 0.2% in Kenya to around 15% in Mexico and Egypt.
"The stark reality is that most people with highly drug-resistant infections are not getting access to the antibiotics they need," said Dr Jennifer Cohn, global access director at the Global Antibiotic Research and Development Partnership (GardP), which led the study.
CRGN infections—found in pneumonia, bloodstream infections and complicated urinary tract infections—are increasingly common and difficult to treat.
When left without effective drugs, they result in longer illness, higher death rates and greater risk of spreading resistant strains.
Cohn and her colleagues argue that global attention has focused too heavily on antibiotic overuse, while underestimating the lack of access in poorer regions.
'Innovative drugs are being introduced in wealthy nations,' she said. 'But the highest burden is not there.'
The researchers studied data from Bangladesh, Brazil, Egypt, India, Kenya, Mexico, Pakistan and South Africa. They matched estimated CRGN cases to sales data of eight effective antibiotics, revealing the large treatment gap.
AMR, which occurs when bacteria evolve to resist treatment, is forecast to kill 1.9 million people a year by 2050 if left unchecked.
The report calls for urgent global investment in equitable access, similar to the international push that brought HIV drugs to Africa.
Barriers to access include limited hospital availability, high treatment costs, and lack of national procurement systems.
'We can't just focus on stewardship in poorer countries and innovation in rich ones,' said Cohn. 'We need both, everywhere, at the same time.'

NBP, Indus Hospital launch blood-donation drive
KARACHI: The National Bank of Pakistan (NBP), in collaboration with Indus Hospital & Health Network, has successfully launched the NBP Blood Donation Drive 2025 across Karachi, Hyderabad, Multan, and Bahawalpur—underscoring the bank's strong commitment to health, humanity, and national responsibility. This life-saving initiative featured awareness sessions followed by full-day blood donation activities, where employees came together to donate blood voluntarily and support Pakistan's ongoing healthcare needs. All donors received free health screenings and testing for nine medical indicators, including Hepatitis B & C, HIV, and more—emphasizing NBP's care for both the nation and its people. Speaking regarding the initiative, NBP President Mr. Rehmat Ali Hasnie shared: 'As the Nation's Bank, we believe that leadership must reflect empathy and action. This campaign is not only about saving lives—it is about building a culture of compassion and public service.' Copyright Business Recorder, 2025

Sindh pushes male vasectomyto 'defuse population bomb'
The Sindh government has launched a renewed drive to slow the province's rapid population growth, which increases annually by about 1.4 million, equivalent to the population of an entire district, by promoting male sterilisation through vasectomy and self-administered contraceptives for women. Sindh Population Welfare Secretary Hafeezullah Abbasi told The Express Tribune that the department, in collaboration with Johns Hopkins University, will conduct door-to-door surveys in all 1,600 union councils. The initiative will also target around five million factory workers through awareness sessions, while school and university students will be educated on the impact of unchecked population growth. "Since men usually make major household decisions, it is important to involve them in these programmes," Abbasi said, adding that 3,000 men in Sindh have already undergone vasectomy, many due to hereditary blood disorders like thalassaemia or because they were living with HIV/AIDS. Abbasi said contraceptive services, including sterilisation, birth-spacing devices, pills and Sayana Press, a self-injectable contraceptive that provides a three-month gap between pregnancies, are being provided in coastal areas and on islands. The Sayana Press option, he added, has been used about 1.3 million times since 2018. Director of Administration Faisal Meher said that contraceptive supplies, including sterilisation kits, IUCDs, implants, injections and pills, are regularly provided to major hospitals, the Health Department and NGOs. Family planning centres in 20 gynaecology wards of nine major hospitals provide IUCDs, which prevent pregnancy for up to 10 years, and implants, effective for 3-5 years. Meher said Sindh's contraceptive prevalence rate was 31% in 2017-18, with targets to raise it to 47% by 2025 and 57% by 2030. He added that male sterilisation cases in Karachi have risen sharply, from just 23 to 2,500 in 2022, as more than 1,000 male mobilisers from HANDS are being trained to promote vasectomy awareness. Early marriages in rural Sindh mean many women have six to eight children by the age of 30, Meher said, underscoring the urgency of the initiative. The programme, supported by Johns Hopkins University, SZABIST University and the Bill & Melinda Gates Foundation, aims to help the province meet its Family Planning 2030 targets. Vasectomy is a surgical procedure that cuts or blocks the vas deferens, preventing sperm from being released during ejaculation. However, it doesn't affect erection, libido, orgasm and ejaculation (though semen won't contain sperm). Vasectomy is a permanent birth control method, but it doesn't impact sexual function or pleasure. Men can resume sexual activity usually 1-2 weeks after the procedure, depending on their doctor's advice.
