Summary
Imported malaria is common in travelers and migrants. This study analyzed 850 malaria cases in Spain, finding Plasmodium falciparum most frequent, especially in VFR-immigrant men.
Area of Science:
- Epidemiology
- Infectious Diseases
- Tropical Medicine
Background:
- Imported malaria is a frequent diagnosis in travelers and migrants.
- The study focuses on imported malaria cases within the Spanish collaborative network for imported diseases (+REDIVI).
Purpose of the Study:
- To describe the epidemiological and clinical characteristics of imported malaria patients in Spain.
- To explore associations between malaria and patient demographics, case type, and exposure areas.
Main Methods:
- Analysis of imported malaria cases registered in the +REDIVI database (October 2009-October 2016).
- Demographic, epidemiological, and clinical data were collected and analyzed.
Main Results:
- 850 malaria cases (7.2% of imported infectious diseases) were identified.
- Malaria was more frequent in men (56.8%) and VFR-immigrants (52.6%).
- Plasmodium falciparum was the most prevalent species (81.5%), particularly in VFR-immigrant men. Sub-Saharan Africa was the primary region of acquisition.
Conclusions:
- Malaria is a significant imported infectious disease in Spain.
- Significant differences in malaria distribution were observed based on gender, case type, and Plasmodium species.
- P. falciparum infection in VFR-immigrant men was the most common malaria diagnosis.
