Loa loa infection in non-endemic area: a case study and disease review

ABSTRACT

Loiasis is a cutaneous filarial parasite of humans caused by the filarial nematode Loa loa, which is transmitted to humans by day-biting Chrysops flies. Human loiasis is confined to the rain forest and swamp forest areas of Western and Central Africa; however; sporadic cases hove been reported from other parts of the world including India. United Arab Emirates is relatively free from arthropod-borne parasitic diseases, but the region remains vulnerable to the introduction of such infections from areas where they are endemic due to a high traffic of a large expatriate population. We report a suspected case of loaiasis in a patient from India who lived and worked in Dubai, UAE, for several years and who had never visited Africa in the past. We assume that this is the first case of loaiasis reported from the gulf region where transmission of the infection has occurred outside the endemic areas
