Fourteen-year experience with imported malaria.
Geographical position, an increasing flow of immigrants and refugees coming from regions where malaria is endemic might further increase those cases of malaria imported to Calabria due to travel on military missions, visiting relatives, business and leisure. However, few reports have been published regarding malaria imported into the southern Italian region of Calabria. Based on data from our laboratory, official reports received from the Italian Ministry of Health and Regional Health Offices, an epidemiological analysis of malaria cases registered in Calabria from January 1988 to December 2001 is reported. The epidemiological and clinical features concerning the cases are discussed. A total of 34 slide-confirmed malaria cases were observed in Calabria during the period in question. Infections were mostly acquired in Africa (84.8%), while remaining infections came from Asia (9.1%) and South America and Europe (6.0%). Length of stay in the endemic area did not increase the infection risk. Etiological diagnosis indicated Plasmodium falciparum as the species most often involved (60.6%), followed by Plasmodium vivax (36.3%) and P. vivax/Plasmodium malariae mixed infection (3.0%). The mortality rate was about 3.0%. The number of cases during the second seven-year period of this study was almost double that of the first seven-year period. Correct chemoprophylaxis was performed by only 27.3% of our studied subjects. Delay of malaria diagnosis ranged between 4 days and 1 month. In conclusion, increases in malaria cases, mostly due to P. falciparum, delay in diagnosis and reporting to the Regional Health Office, as well as the increasing arrival of refugees from endemic areas, are epidemiological concerns in Calabria, the southernmost region of continental Italy.
