Ancient Killer Is Rapidly Gaining Resistance to Antibiotics, Study Warns

Researchers sequenced thousands of Salmonella Typhi samples across South Asia and found rapidly rising drug resistance.

Some strains are also developing azithromycin resistance, leaving few effective oral antibiotics against typhoid.

The resistant strains are spreading internationally, raising the risk that harder-to-treat typhoid becomes more common worldwide.

The findings strengthen the case for broader typhoid conjugate vaccine use to help curb transmission.
