Chikungunya infection in children

Area of Science:

• Virology
• Epidemiology
• Pediatrics

Background:

• Chikungunya virus (CHIK) causes Chikungunya fever, transmitted by Aedes aegypti and Aedes albopictus mosquitoes.
• The disease has a median incubation period of 2 to 4 days and can be transmitted vertically from mother to child.
• Clinical manifestations range from asymptomatic to severe, with children being a high-risk group for severe outcomes.

Purpose of the Study:

• To summarize the clinical manifestations and treatment of Chikungunya fever.
• To highlight the distinct clinical features and risks in pediatric populations.
• To provide guidance on symptomatic management, including medication considerations.

Main Methods:

• Review of clinical manifestations of Chikungunya fever.
• Analysis of risk factors and vulnerable populations, particularly children.
• Summary of current treatment strategies and drug recommendations.

Main Results:

• Common symptoms include fever, rash, arthralgia, and conjunctivitis.
• Severe manifestations and distinct clinical features are observed in children.
• Neurological complications and gastrointestinal symptoms in infants are noted.
• Symptomatic treatment with paracetamol is recommended; NSAIDs are generally avoided but may be used in convalescence.

Conclusions:

• Chikungunya fever presents a broad spectrum of illness, with children facing increased risk of severe disease.
• Prompt recognition of clinical features and appropriate symptomatic management are crucial.
• Further research into pediatric Chikungunya manifestations and optimal treatment is warranted.
