Antimicrobial-resistant nontyphoidal Salmonella infection following international travel — United States, 2018–2019
Antimicrobial resistance in nontyphoidal Salmonella (NTS) can limit treatment options. We assessed the contribution of international travel to antimicrobial-resistant NTS infections.
We describe NTS infections reported to the Foodborne Diseases Active Surveillance Network during 2018–2019 that were screened for genetic resistance determinants, including those conferring decreased susceptibility to first line agents (ciprofloxacin, ceftriaxone, or azithromycin).
International travel is a substantial risk factor for antimicrobial-resistant NTS infections. Understanding risks of resistant infection could help target prevention efforts.
