A map showing flu hotspots, including the potentially Aussie flu strain which has arrived in the UK, has shown parts of South Tyneside among the areas with the highest cases reported.
The interactive map shows the areas with the worst outbreaks of the illness reported.
Updated every three minutes, the map shows all types of the flu bug, including the potentially deadly Aussie flu strain which has arrived in the UK.
The map indicates a gradient of no reports (blue) to "very high reports" (red) of all types of flu as reported by users.
The map shows the Whitburn and Marsden areas in red, the highest category, with South Shields, Jarrow, Hebburn and the rest of South Tyneside also fairly high.
Users upload reports themselves, and the data from the FluSurvey map is used by scientists at Public Health England and London School of Hygiene and Tropical Medicine.
