Novel influenza A viruses, distinct from seasonal strains, pose a public health risk. This review examines antiviral effectiveness for treating and preventing infections from avian and swine origins, guiding clinical practice.
Area of Science:
- Virology
- Infectious Diseases
- Public Health
Background:
- Novel influenza A viruses (avian or swine origin) are antigenically distinct from seasonal influenza.
- Human infections with novel influenza A viruses, including highly pathogenic avian influenza A(H5N1), necessitate evidence-based treatment guidelines.
Purpose of the Study:
- To review and summarize available data on antiviral use in humans with novel influenza A virus infections.
- To assess the effectiveness of antiviral treatment and postexposure prophylaxis for avian and swine influenza A virus infections.
- To discuss combination antiviral therapy and identify research gaps.
Main Methods:
- Systematic review of published literature on human cases of novel influenza A virus infections treated with antivirals.
- Inclusion of in vivo studies on antiviral efficacy against avian and swine influenza A viruses.
- Analysis of data on antiviral treatment and postexposure prophylaxis.
Main Results:
- Evidence on antiviral effectiveness for novel influenza A virus infections is synthesized.
- Considerations for combination antiviral therapy are discussed.
- Key questions for future research are identified to improve evidence base.
Conclusions:
- Antiviral use for novel influenza A virus infections requires further evidence-based recommendations.
- Research is needed to optimize treatment and prophylaxis strategies.
- Understanding antiviral effectiveness is crucial for managing emerging influenza threats.
