Little is known about the epidemiology of typhoid and paratyphoid fever in Nepal. We aimed to elucidate the molecular and clinical epidemiology of Paratyphi A in Nepal. Isolates were collected from 23 cases of bacteremia due to Paratyphi A between December 2014 and October 2015. Thirteen patients (57%) were male, and the median age was 21 years. None of the patients had an underlying chronic disease. All Paratyphi A isolates were sensitive to ampicillin, trimethoprim/sulfamethoxazole, ceftriaxone, and chloramphenicol. All isolates were resistant to nalidixic acid and were categorized as intermediately susceptible to levofloxacin. Phylogenetic analysis revealed close relatedness among the isolates, including several clonal groups, suggesting local spread. Patients with bacteremia due to Paratyphi A in Kathmandu, Nepal, were relatively young and nondebilitated. Improving control of . Paratyphi infections should focus on effective infection control measures and selection of empirical therapy based on current resistance patterns.
