Typhoid fever is caused by a type of Salmonella bacteria - Salmonella enterica serotype Typhi (S. Typhi) - and is more common in Africa, Asia and Latin America. In 2022, scientists from across the globe sequenced the genomes of 3,489 S. Typhi strains contracted from 2014 to 2019 in Nepal, Bangladesh, Pakistan and India. Not only is this strain resistant to older medications, but more worryingly, it is resistant to newer, more powerful drugs as well. It is vital to seek treatment early, as untreated typhoid fever can lead to lasting health impacts and death. To prevent typhoid fever, the CDC recommends getting vaccinated before traveling to countries where it is common.
