Influenza, Human Clinical Trial
Official title:
Burden of Influenza at Emergency Department (ED) Level in European Countries
This study plans to conduct enhanced influenza surveillance at a hospital emergency department level independent of underlying influenza-like symptoms.
Study objectives
Primary:
- Measure the proportion of non-traumatic emergency department (ED) visits infected with
influenza during the peak of the influenza season
Secondary:
- Describe the demographic and medical profile of influenza-related and
non-influenza-related visits
- Identify socio-demographic or other risk factors associated with ED visit outcome
- Describe the influenza positivity rate among ED visits for different causes
- Measure the proportion of influenza positive patients without classical ILI symptoms
