Blackpool now has one of the fastest rising infection rates in England joining Ribble Valley, Pendle and Hyndburn in the top five.
It comes after the seaside town was this week declared a Covid "enhanced response area", bringing it into line with the rest of the county, with extra measures being put in place to tackle a rise in the Delta variant.
The latest Public Health England data shows Blackpool's weekly case numbers have nearly doubled giving it an infection rate of 198.6. This is nearly three times the new national average.
In the week of testing to June 11, its rate has shot up from 103.3 after a total of 277 confirmed cases.

Blackburn with Darwen continues to have Lancashire's highest infection rate at 594.5. However new figures suggest the recent surge has now peaked with the seven-day rate dropping on each successive day since June 7.
Seven of the top 10 infection rates in England can now be found in Lancashire - including all of the top six - with 12 out of 14 boroughs above the 100 mark.
Lancaster now has the lowest rate in the county at 80.8 after West Lancs saw its rate jump from 76.1 to 102.4.
Of the 315 local areas in England, 283 (90%) have seen a rise in rates - including all 14 Lancashire boroughs - while 28 (9%) have seen a fall and four remain unchanged.
The five areas with the biggest week-on-week rises are: Ribble Valley (up from 244.7 to 477.9); Pendle (141.1 to 319.2); Hyndburn (275.2 to 446.7); Blackpool (103.3 to 198.6); and Warrington (55.2 to 148.6).
The figures, for the seven days to June 11, are based on tests carried out in laboratories (pillar one of the Government’s testing programme) and in the wider community (pillar two).
The list below has been calculated by the PA news agency, based on Public Health England data published yesterday (June 15) on the Government’s coronavirus dashboard.
Data for the most recent four days (June 12-15) has been excluded as it is incomplete and does not reflect the true number of cases. The rate is expressed as the number of new cases per 100,000 people.
