A potentially deadly strain of flu has spread to Blackpool and the Fylde coast, according to data used by health experts.
The interactive map which allows users to upload reports of 'Aussie flu' themselves shows the areas with the worst outbreaks of the illness.
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 data from the FluSurvey map is utilised by scientists at Public Health England and London School of Hygiene and Tropical Medicine.

Public health officials have warned people who are eligible for a free flu vaccine to get it ‘without delay’.
People should recover from normal flu within a week or so, although some symptoms like a cough can last longer.
If you are still ill after seven days, it is a possible indication of a more serious sickness.
