The number of lives lost around the world due to infections that are resistant to the medications intended to treat them could increase nearly 70 percent in the next 25 years.

The number of lives lost around the world due to infections that are resistant to the medications intended to treat them could increase nearly 70 percent by 2050, a new study projects, further showing the burden of the ongoing superbug crisis.

"We need appropriate attention on new antibiotics and antibiotic stewardship so that we can address what is really quite a large problem," he said.

The researchers found that the pathogen-drug combination that had the largest increase in causing the most burden among all age groups was methicillin-resistant Staphylococcus aureus, or MRSA. For this combination – the antibiotic methicillin and the bacteria S. aureus – the number of attributable deaths nearly doubled from 57,200 in 1990 to 130,000 in 2021.

According to the data, the regions of the world most affected by AMR and attributable deaths are South Asia, Latin America and the Caribbean, and sub-Saharan Africa – and many of these regions don't have equitable access to quality care, Murray said. Yet he warned that the forecast models do not consider the emergence of new superbugs "and might lead to underestimation if new pathogens arise."

"I'm somebody who's lived with antimicrobial resistance affecting my family for the last eight years. My husband nearly died from a superbug infection. It's actually one of the infections that's highlighted in this paper," said Strathdee, who serves as co-director of the, suddenly developed severe stomach cramps.
