Rising Typhoid Resistance Threatens Global Health Systems

A new study published in The Lancet Microbe confirms a significant rise in extensively drug-resistant (XDR) strains of Salmonella enterica serovar Typhi, the bacteria causing typhoid fever. Researchers analyzed over 3,489 bacterial genomes collected between 2014 and 2019 from various regions in South Asia, revealing that traditional effective antibiotics like ampicillin and fluoroquinolones are losing their potency against these emerging strains. This alarming trend signifies the return of a previously controlled health threat, undermining decades of public health progress in developed nations.
