ObjectiveEvaluation of the epidemiological situation of imported malaria in Poland in 2013 compared to the data from previous years.Material And MethodsThe assessment was performed based on the results of the analysis of individual reports sent to the NIPH-NIH by sanitary-epidemiological stations and aggregated data published in the annual bulletins "Infectious diseases and poisonings in Poland". Cases were registered according to the case definition criteria applicable in the EU countries.ResultsIn 2013, a total of 36 imported malaria cases were registered in Poland, 15 more than in 2012. No deaths were recorded. As much as 80% of all cases were imported from African countries, of whom the majority came from Nigeria, 14% from Asia and 6% from South America. Concurrent infection with dengue virus was confirmed in one person coming back from Philippines. Plasmodium species was determined in 35 of 36 cases by blood film or PCR test. Invasion with P. falciparum and P. vivax was found in 23 (66%) and 9 (26%) cases, respectively. There was also one case of each of the following: P. ovale, P. malariae and mixed invasion. As in previous years, in most cases, the invasion was associated with tourist trips (47%) or work-related travels (36%). Immigrants or students visiting the country of origin accounted for 11% of patients, in two cases (6%) purpose of the journey was not determined. As many as 7 patients used chemoprophylaxis, including two persons who took drugs in compliance with the recommendations.ConclusionsDespite a significant increase in the number of cases compared to previous years, the total number of imported malaria remains low. Persistent large number of delays in the diagnosis and a high percentage of severe malaria cases indicate the need to raise doctors awareness of the possibility of malaria incidence. Travelers should be also constantly reminded of the need to inform their GPs about the stay in the malaria endemic areas in the event of fever after returning.
