Plasmodium falciparum malaria recrudescence occurring 2.5 years after leaving an endemic country

Malaria tropica is almost exclusively diagnosed within two months after returning from an endemic country. We present here a male patient with severe P. falciparum malaria diagnosed 2.5 years after returning from Burkina-Faso. We speculate that our patient was chronically infected with PF malaria for more than 2 years, with an undetectable parasite index and without symptoms. Because of waning immunity clinically overt PF malaria was able to develop. This case illustrates the importance of malaria suspicion as a cause of illness in immigrants from malaria-endemic countries. Even when these immigrants did not travel for a long time, malaria should be considered in patients with typical symptoms.
