FLU cases have doubled within a week in the UK according to figures released by Public Health England (PHE), and the death toll over the past three months has surpassed 40.
Nearly two million people are showing flu-like symptoms as rates hit their worst level since this year’s monitoring began in September.
Figures released by Public Health England show an increase across Scotland, England, Wales and Northern Ireland as health authorities warn that it will only get worse.
Cases have increased by 85 percent in England and 55 percent in Wales, while Scotland and Northern Ireland have seen increases of 139 and 50 percent respectively.
After months of fairly low activity, the number of cases has surged since the turn of the year, coinciding with a huge drop in temperatures.
None of the four nations have entered into an epidemic level but England and Wales have now crossed into the ‘low’ threshold.
There are five scales ranging from ‘low’ to ‘very high’, which is considered an epidemic.
Each country sets its own epidemic level based on how often flu-like symptoms are reported per 100,000 patients.
There were 14.8 GP consultations per 100,000 this week, a rise from 8.4 while Wales rose from 9.5 to 14.7.
