BackgroundSpain obtained the official certificate of malaria eradication in 1964. However, imported malaria cases have been increasing during the last few decades in this country. This study aims to describe the clinical and epidemiological features of patients diagnosed with malaria on Gran Canaria Island.MethodsA retrospective study was conducted based on case review of all patients diagnosed with malaria microbiologically confirmed from 1993 to 2006, at the three referral teaching hospitals on Gran Canaria Island.ResultsOne hundred eighty-four episodes in 181 patients were diagnosed, 170 of them were analyzed. Most of them (82%) were travelers. Nearly 15% (14.7%) declared having had some chemoprophylaxis, but only half of them completed the treatment. Twenty cases (10.9%) were diagnosed who had just arrived as immigrants, mainly children. Malaria was acquired in Africa by 94.7% of the cases and Plasmodium falciparum was responsible for the majority of the cases (84.1%). Clinical and epidemiological differences were observed among different groups of patients formed by their origin and travel purposes. At least one indicator of severe malaria was established in 22.9% of the cases. However, global mortality was 3.8%.ConclusionsMalaria in Gran Canaria Island is imported from endemic areas, mainly from African countries, observed mostly among young adult males, but clinical and epidemiological features may change among different groups of patients. The number of immigrants diagnosed with malaria is increasing in this area nowadays.© 2011 International Society of Travel Medicine.
