Imported Infections: Managing Malaria and Dengue in Clinical Practice for Travel Consultation and Epidemiological Surveillance

The consultation focuses on the management of imported infections such as malaria and dengue, with a world map and a poster on mosquito-borne diseases in the background. The atmosphere is professional, emphasizing treatment and epidemiological surveillance in travel consultations.

The increase in international travel has led to a rise in the incidence of imported infections, such as malaria and dengue, which present significant challenges in clinical practice. These vector-borne diseases are common in tropical and subtropical regions, and their proper management is crucial to prevent severe complications and the spread in non-endemic areas.

Diving Deeper into Clinical Management

Malaria, caused by parasites of the genus Plasmodium, remains one of the most common infections among travelers returning from sub-Saharan Africa. Early diagnosis and appropriate treatment are essential to avoid severe complications. According to a study conducted at the Hospital for Tropical Diseases in London, malaria caused by Plasmodium falciparum was the most common diagnosis among travelers requiring hospitalization [1].

On the other hand, dengue, a viral disease transmitted by mosquitoes of the genus Aedes, is prevalent among travelers visiting Southeast Asia and Latin America. Epidemiological surveillance is fundamental to identify outbreaks and prevent local transmission. An analysis of surveillance data in Europe highlighted an increase in dengue infections, underscoring the importance of travel consultation for prevention [2].

The clinical management of these infections requires a multidisciplinary approach that includes accurate diagnosis, timely treatment, and patient education on preventive measures. Travel consultation is a valuable tool to reduce the risk of imported infections, providing information on malaria prophylaxis and protective measures against mosquito bites [3].

Conclusions

The management of malaria and dengue in clinical practice requires a deep understanding of the epidemiological and clinical characteristics of these imported infections. The implementation of epidemiological surveillance strategies and the promotion of travel consultation are essential to improve clinical outcomes and prevent the spread of these diseases. Healthcare professionals must be prepared to face these challenges through continuous updates of their knowledge and clinical skills [4].
