Risk of Highly Pathogenic Avian Influenza A/H5N1 Virus in Pediatrics
1Department of Pediatrics, Infectious Disease Section, Baylor College of Medicine, Houston, TX 77030, United States.
Insights
Highly Pathogenic Avian Influenza A/H5N1 virus is spreading in the US. Children face a higher risk of severe illness, necessitating their inclusion in vaccine and treatment research.
Area of Science:
- Virology
- Public Health
- Epidemiology
Background:
- Highly Pathogenic Avian Influenza A/H5N1 virus (HPAI A/H5N1) has been detected across multiple US states starting in 2024.
- While the current risk of human infection remains low, the evolving nature of the virus presents potential challenges.
Purpose of the Study:
- To highlight the elevated risk of severe HPAI A/H5N1 infection in children.
- To advocate for the prioritization of pediatric populations in preventive strategies against HPAI A/H5N1.
Main Methods:
- This study is a review of current HPAI A/H5N1 surveillance data and risk assessments.
- Analysis of HPAI A/H5N1 epidemiological trends and their implications for public health.
Main Results:
- Children represent a vulnerable demographic for severe outcomes from HPAI A/H5N1 infection.
- The continuous evolution of HPAI A/H5N1 underscores the need for proactive public health measures.
Conclusions:
- Preventive strategies must prioritize children, including their inclusion in vaccine and therapeutic clinical trials.
- Vaccine implementation plans should specifically address the needs of pediatric populations to mitigate HPAI A/H5N1 risks.
Abstract:
Although the current risk of avian influenza A/H5N1 Virus infection in humans is low, children represent a high-risk group for severe disease as virus evolves. A/H5N1 vaccine development, clinical trials, and implementation strategies for infants and children should be prioritized. Highly pathogenic avian influenza A/H5N1 Virus has been found in multiple US states since 2024. While human infection risk is currently low, children are a high-risk group for severe infection as the virus evolves. Preventive efforts should prioritize children in vaccine and therapeutic clinical trials and vaccine implementation strategies.
