Insights
A previously healthy child contracted avian influenza A (H5N1) from poultry, developing severe respiratory distress and succumbing to the infection despite intensive care. This case highlights the critical threat of H5N1 avian flu in humans.
Area of Science:
- Virology
- Infectious Diseases
- Public Health
Background:
- Avian influenza A (H5N1) poses a significant zoonotic threat.
- Human infections are rare but associated with high mortality.
- Poultry contact is a primary risk factor for human H5N1 transmission.
Observation:
- A 9-year-old girl presented with a 3-week history of respiratory symptoms, escalating to severe insufficiency.
- She had recent close contact with infected domestic poultry.
- The patient developed acute respiratory distress syndrome (ARDS) and diarrhea, requiring mechanical ventilation.
Findings:
- Throat swab RT-PCR and viral culture confirmed avian influenza A (H5N1) infection.
- Despite supportive care, including mechanical ventilation, the patient's condition rapidly deteriorated.
- The patient expired within 4 days of hospital admission.
Implications:
- This case underscores the severe pathogenicity of avian influenza A (H5N1) in previously healthy children.
- It emphasizes the importance of prompt diagnosis and isolation in suspected human H5N1 cases.
- Public health surveillance and measures to prevent human-animal contact are crucial for mitigating H5N1 risks.
Abstract:
A previously healthy, 9-year-old girl was admitted to the hospital with respiratory insufficiency. She had mild and severe respiratory symptoms for 3 weeks and 4 days before admission, respectively. She had a history of close contact with her domestic poultry, which was infected with avian influenza A (H5N1). She was isolated with the air-borne transmission prevention mode of treatment. Acute respiratory distress syndrome (ARDS) was documented from the time of admission and mechanical ventilation was introduced without improvement. She had multiple episodes of diarrhea for 2 days. Her condition deteriorated and she expired in 4 days. Throat swab RT-PCR and viral culture for avian influenza A (H5N1) were positive.
