From 2000 to 2005, we investigated prospectively 98 cases of imported non– malaria (48 , 34 , and 16 ). Latency period between return and clinical attack exceeded three months in 40% of the patients. It was longer in travelers who had taken chemoprophylaxis. Time to diagnosis was longer in patients with infection and in those with late-onset first attack. Parasite density was often lower than 500/μL, especially in malaria. Relapses were diagnosed in 18% of all malaria episodes. Eight (17%) and 2 (6%) malaria episodes were due to relapse despite standard primaquine therapy. Diagnosis of imported non-falciparum malaria is often challenged by long latency period and low parasite density. In addition, the substantial relapse rate despite standard primaquine therapy supports the use of a higher dose of primaquine to eradicate and malaria effectively.
