THE GIHSN

The Global Influenza Hospital Surveillance Network (GIHSN) is a platform able to generate strong epidemiological and medical evidence on influenza severity and to support vaccine strain selection through timely sharing of clinical and laboratory data. GIHSN can inform policy decisions and serve as a network for improved respiratory viruses surveillance capacity building and response.

GIHSN in SCIENCE: Uncertain effects of the pandemic on respiratory viruses

SARS-CoV-2 and the associated non-pharmaceutical interventions severely disrupted the circulation of respiratory viruses. It could mean a future shift in the epidemiology of respiratory diseases, the potential for new epidemic threats, or larger outbreaks than previously observed.

--> INFO COVID-19 <--

The GIHSN, supported by the Foundation for Influenza Epidemiology, can be a strong platform for severe COVID-19 surveillance and research. GIHSN systematically collects epidemiological data (e.g. clinical characteristics, outcome, etc.) on patients hospitalized with acute respiratory illness. Respiratory specimens are collected on each patient; swabs are stored and most laboratories have capacity to do further analysis. More than 10,000 samples are collected every year in approximately 100 hospitals across 20 sites worldwide. If you are interested to partner with the GIHSN as part of a research project or grant submission, please contact This email address is being protected from spambots.

THE GIHSN

The Global Influenza Hospital Surveillance Network (GIHSN) is a network of 100+ hospitals in 25+ countries performing active surveillance following the same core protocole.

More than 4,000 documented cases of hospitalizations from severe influenza have been generated in the recent season (>1,000 RSV cases).

Close to 1,000 virus sequence results have been uploaded on GISAID last year.

The GIHSN is supported by a dedicated fund under the Fondation de France umbrella : the Foundation for Influenza Epidemiology, which provides catalytic funding complementary to national funding.

Not-for-profit institutions with proposals aligned with the GIHSN mission are eligible to apply for partial funding through an annual call for proposals.
