Unspecified malaria is a classification entity within the WHO ICD-10 system designated as B54, used solely to categorize malaria cases without specification of species [1]. Surveillance among U.S. service members in 2017 recorded 17 cases attributed to unspecified malaria species, representing 53.1% of that year's 32 reported malaria cases and the highest proportional share during the surveillance period [2].
