Seasonal influenza (flu) affects low-, middle-, and high-income countries around the world and is a significant cause of illness and death.
Explore seasonal influenza burden in your country
- Age groups you want to analyze
- Influenza seasons (years) you want to estimate
- Number of hospitalizations and/or deaths by age group per season
The Seasonal Influenza Disease Burden Estimator (Flu Tool) aims to help countries and officials better understand their seasonal flu burden, even if their national surveillance data are limited.
Using a multiplier-based approach, the tool estimates the number of flu cases, hospitalizations, and/or deaths by season, including for individual age groups, across a country’s entire population or specific sub-populations. This can help national-level decisionmakers more effectively prepare for seasonal flu epidemics and future flu pandemics.
Refine your results with more options:
- Define a sub-population of your country
- Customize age groups
- Modify expansion factors for underdetected hospitalizations and/or deaths
- Adjust multipliers for all burden severity levels.
