Good Morning Britain's Dr Hilary has advised which 'red flag' symptoms could mean your child has Strep A.
In the UK, eight children have died from the infection this week causing concern in many other parents. The bacteria can cause a life-threatening illness called invasive Group A Streptococcal disease.
The UK Health Security Agency (UKHSA) said there had been a rise in rare invasive Group A strep this year, particularly in children under 10. Group A strep bacteria can cause many different infections, ranging from minor illnesses to deadly diseases.
