Antibiotic resistance is indeed worsening globally, affecting a growing number of bacterial infections. Recent data shows that between 2018 and 2023, resistance rates increased in over 40% of monitored antibiotics. This translates to an average annual rise of five to fifteen percent.

In 2023, one in six laboratory-confirmed bacterial infections worldwide was resistant to antibiotic treatments. For urinary tract infections, the situation is even more alarming, with resistance rates hitting one in three cases in certain regions.

Geographically, the highest resistance rates are found in the WHO South-East Asian and Eastern Mediterranean regions, where up to one in three infections are resistant. The African region follows closely, with one in five infections resistant, while the Americas report one in seven. Countries with weaker health systems and limited diagnostic capabilities are experiencing the fastest increases and the highest burdens of resistance.

Resistance is rising most rapidly among Gram-negative bacteria, like E. coli and Klebsiella pneumoniae. These pathogens are showing increased resistance to critical antibiotics, including third-generation cephalosporins and carbapenems. In some areas, over 40% of E. coli bloodstream infections and more than 55% of Klebsiella pneumoniae infections are resistant to first-line treatments.

The situation is dire for last-resort antibiotics, such as carbapenems. Resistance to these drugs is on the rise, narrowing treatment options and forcing reliance on more expensive, less accessible alternatives. Projections suggest that resistance to these last-line drugs could double by 2035 compared to levels seen in 2005.

Antibiotic resistance is now recognized as a global health crisis, contributing to at least 1.27 million deaths annually and linked to nearly 5 million deaths worldwide. If current trends continue, future projections estimate up to 39 million deaths over the next 25 years.

Several factors are driving this crisis. The overuse and misuse of antibiotics, poor infection control practices, substandard drugs, and insufficient surveillance, especially in low- and middle-income countries, are all contributing to the problem.

Resistance is rising fastest where surveillance and stewardship are weakest. The effectiveness of both common and last-resort antibiotics is diminishing, making infections harder to treat and increasing the risk of mortality. The urgency for improved surveillance, stewardship, and innovation in diagnostics and drug development has never been greater.
