Malaria is a parasitic disease causing substantial morbidity and mortality globally. Malaria is a potentially severe and fatal disease in non-immune individuals. In areas of intense transmission infections individuals acquired immunity that protect against clinical disease. Nonetheless, immunity is not regarding sterilizing and repeated infections often result in an asymptomatic carriage of malaria parasites. These chronic apparently asymptomatic infections have been associated with anemia, cognitive dysfunction and adverse events during pregnancy. Global migration has increased over the last decade and has resulted in an increasing number of migrants from malaria endemic regions arriving in non-endemic countries. Migrants from malaria endemic countries may carry asymptomatic infections with malaria parasites, as well as other parasitic infections such as strongyloides and schistosomiasis, with a possible negative impact on health in this group. The prevalence of asymptomatic malaria and other parasites is not fully elucidated in migrants from different regions. Moreover, the longevity of asymptomatic carriage of malaria parasites in absence of re-exposure is not known. The aim of this study is to assess the prevalence of malaria parasites and other parasitic infections in migrants in Sweden, both newly arrived and migrants with longer residency, and intend to evaluate the need for screening for various parasitic infections in migrants arriving in Sweden. Moreover, this study will also assess antibody responses to malaria and other parasitic diseases.
