FLU rates have almost doubled in just one week, prompting doctors to call for parents to get their children vaccinated.

Cases rose by 88 per cent last week in Brighton and Hove.

Last winter thousands of two and three-year-olds were at risk of becoming seriously ill as only two in every five had been vaccinated.

Dr Andrew Hodson said it is crucial parents have their children vaccinated as they are “super spreaders” of flu.

“It is important we protect young children from the flu and we know children tend to be ‘super-spreaders’ of flu, so protecting them is crucial,” he said.
