    Abstract

    A 74-year-old patient of Belgian origin living in Antwerp, who never travelled outside Europe
    and did not leave Belgium in the past 3 years, was diagnosed with malaria tropica mid-January
    2015. Twelf % of the red blood cells were infected with Plasmodium falciparum. At the end of
    January she recovered after treatment with artesunate, followed by piperaquine tetraphosphate,
    dihydroartemisinin and doxycycline. Despite active case finding, no other cases of malaria were
    found. Possible sources of infection were investigated. Also mosquito trapping (BG-Sentinel™) and
    larval sampling were performed in the proximity of her house and in the Zoo of Antwerp. Source
    finding did not provide definitive results, but Anopheles claviger, a competent vector, was found
    at 800m from the patients house. However, the low number of Anopheles caught and the winter
    season. make local transmission unlikely. The most probable route of infection was an incidental
    contact with an infectious mosquito, imported by suitcase, although we cannot exclude transmission
    by local vectors. Even without a travel history, considering malaria in patients with ongoing fever
    and hemolysis, is regarded as important.
