A study from Caltech reveals that drought increases antibiotic-resistant microorganisms in soil, impacting public health. The research shows a strong correlation between regional aridity and antibiotic resistance in clinical settings across over 100 countries. Droughts create effects similar to antibiotic overuse, driving resistance. The findings highlight the need for better diagnostics and therapeutic approaches, as well as the importance of the One Health approach in addressing the interconnectedness of health across species and environments.
