“…Studies conducted to clarify doubts in the diagnosis of febrile disease of unknown etiology point to the need for immediate laboratory confirmation during outbreak/epidemic situations, as the many clinical manifestations may not characterize the diseases [48,49]. Serologic evidence of hantavirus has been identified in patients with clinical suspicion of dengue, malaria, influenza, chikungunya, rickettsial infections, leptospirosis, and HIV [50,51,52,53,54,55,56,57,58,59]. Thus, the results of this study in which the initial diagnosis was malaria and dengue, reinforce the need for an alert to health professionals working in endemic areas of malaria regarding the importance to investigate the hantavirus infection, as here performed with the population from Colniza.…”
