The Global Influenza Hospital-based Surveillance Network (GIHSN) is a worldwide platform to generate timely and high-quality epidemiological data and virologic al information on severe influenza.
The GIHSN has three main objectives:
- Characterize the profile of patients with severe influenza disease;
- Quantify the distribution of the different influenza viruses (A/H1N1, A/H3N2, B/Yamagata, and B/Victoria) among these severe cases; and
- Link influenza virus Whole Genome Sequence (WGS) and clinical data to better support vaccine strain selection.
Hospitals from this network use an active standardized surveillance protocol. Data from the participating GIHSN sites are then shared and used to prepare a combined network analysis, published in peer-reviewed journal and/or presented to international conferences.
Since 2015 the GIHSN is supported by the Foundation for Influenza Epidemiology (dedicated funding under the aegis of the Fondation de France). Not-for-profit institutions with proposals aligned with the GIHSN mission are eligible to apply for partial funding through an annual call for proposals.
