Introduction
​

The aim of the 'Flu Syndrome' Advanced Health Indicator (AHI®) is to contribute to the monitoring of flu syndromes in France by providing information that complements that of the Sentinelles and Grog networks. The model used for the 'Flu Syndrome' IAS® is based on the monitoring of a set of drugs prescribed in cases of suspected seasonal flu in France, and uses the analysis and representation methods developed by OpenHealth. This indicator is highly correlated with data from the Sentinelles network. The IAS® is calculated each day using a temporal smoothing method: information from the previous seven days and the following seven days is taken into account to calculate the value for a given day.

For each of the IAS®, these are weighted baskets of medicines and healthcare products dispensed over the counter in pharmacies and pathology markers.
