Taipei, Sept. 23 (CNA) Taiwan has reported its first local paratyphoid fever case of the year, involving a man in his 20s of foreign nationality who developed fever, diarrhea and headaches in late August, the Centers for Disease Control (CDC) said Tuesday. Lin said the patient spent his entire incubation period in Taiwan, so the case was classified as locally transmitted. The source of infection is under investigation, though the patient reported no consumption of untreated water, raw food, or seafood, she added. As of Sept. 22, Taiwan had logged one paratyphoid case this year, CDC Epidemic Intelligence Center Director Kuo Hung-wei (郭宏偉) said at the briefing. Between 2021 and 2025, Taiwan reported one, six, 26, three, and one local case, respectively, along with a few imported cases from Indonesia, India and Cambodia, Kuo added, citing CDC data.
