Alongside flu, cases of RSV have also increased, with the highest positivity rate being in kids under the age of five.
Dr Conall Watson, Consultant Epidemiologist at the UKHSA, said: "Over recent weeks RSV rates have been rising across all age groups, most notably in the under fives. "RSV is unfortunately common at this time of the year and can be severe for children under two – particularly for babies and those born prematurely.
"Everyone should try and avoid spreading respiratory viruses to young children – use tissues, wash hands and avoid visiting babies if you are unwell." He added that if you're worried your child has cold symptoms with unusual breathing or trouble feeding, then you should contact your GP or NHS 111.When it comes to symptoms of flu, they may at first, seem like a common cold.
