[Dengue fever: an emerging infectious disease]

Area of Science:

• * Infectious Diseases
• * Virology
• * Public Health

Background:

• * Dengue fever is an arboviral disease caused by four serotypes of the Flavivirus genus.
• * Transmitted by Aedes mosquitoes (A. aegypti, A. albopictus), it is an emerging threat, particularly for travelers and in temperate regions.
• * The disease presents with diverse clinical manifestations, from asymptomatic to severe forms.

Purpose of the Study:

• * To provide a comprehensive overview of dengue fever as an emerging infectious disease.
• * To highlight diagnostic approaches, treatment strategies, and prevention measures.
• * To discuss the disease's epidemiological significance and public health implications in France and its territories.

Main Methods:

• * Review of scientific literature on dengue fever.
• * Analysis of diagnostic methods based on disease stage and viral kinetics.
• * Examination of current prevention and surveillance strategies.

Main Results:

• * Dengue fever diagnosis requires specific virological tests.
• * Treatment is primarily symptomatic.
• * Prevention involves personal anti-vectorial measures, health professional education, and community mobilization against mosquito breeding sites.

Conclusions:

• * Dengue fever is a significant emerging infectious disease requiring robust surveillance and control measures.
• * Effective prevention relies on integrated strategies targeting vectors and human behavior.
• * The Dengvaxia vaccine is licensed but not recommended for specific populations in France.
