Ans. Drug-resistant typhoid refers to strains of the bacteria Salmonella Typhi that have developed resistance to commonly used antibiotics, such as fluoroquinolones and third-generation cephalosporins. It is a concern in India because the country has been experiencing a rise in cases of drug-resistant typhoid, particularly in densely populated urban areas with inadequate sanitation and access to clean water. The spread of drug-resistant strains makes treatment more challenging and can lead to increased mortality and morbidity rates. Efforts are being made to enhance surveillance, promote vaccination, and improve sanitation and hygiene practices to combat this issue.
