Hantavirus Infections in Children

Area of Science:

• Infectious Diseases
• Virology
• Public Health

Background:

• Hantaviruses, found in the Americas (New World) and Eurasia (Old World), cause severe diseases.
• New World hantaviruses lead to hantavirus cardiopulmonary syndrome (HPS) with up to 33% mortality.
• Old World hantaviruses cause hemorrhagic fever with renal syndrome (HFRS) with up to 15% mortality.

Purpose of the Study:

• To highlight the importance of clinical suspicion for diagnosing hantavirus infections.
• To outline available diagnostic modalities and crucial supportive care strategies.
• To emphasize the need for prompt recognition and transfer to tertiary care centers.

Main Methods:

• Review of existing literature on hantavirus epidemiology, clinical presentation, diagnosis, and management.
• Discussion of diagnostic tools including blood smear evaluation, serology, and PCR.
• Overview of supportive care interventions such as mechanical ventilation, dialysis, and ECMO.

Main Results:

• Hantavirus infections require heightened clinical suspicion due to nonspecific symptoms.
• Diagnostic methods range from basic blood smears to advanced molecular tests.
• Advanced supportive care at tertiary centers can improve patient outcomes.

Conclusions:

• Early recognition and rapid transfer to tertiary care are critical for managing severe hantavirus infections.
• Pediatricians must be vigilant for hantavirus cardiopulmonary syndrome due to its rapid progression in children.
• While specific antiviral therapies are limited, timely supportive care significantly impacts survival rates.
