Influenzanet is a system to monitor the activity of influenza-like-illness (ILI) with the aid of volunteers via the internet
Below we map the reported levels of ILI activity from our participants around the country. The map shows a gradient from no reported ILI (blue) to very high ILI (red). Please note that caution should be used in interpreting the levels of ILI activity shown on the map, as the data may be based on small numbers. The latest HPSC Weekly Influenza Surveillance Report can also be viewed online.
Maps are automatically updated every hour, and new participants are most welcome: registration only takes a few clicks!
