This common childhood infection shows itself in the appearance of a bright red rash on both cheeks.
Sometimes known as fifth disease and erythema infectiosum, slapped cheek syndrome can affect people of all ages.
It is caused by a virus called parvovirus B19 and you may not even realise if you have been infected with this as the symptoms are mild.
Your child may have a high temperature, sore throat or headache to begin with. They are most contagious at this point. Up to seven days later they will develop a bright red rash on both cheeks.
Finally, the rash will spread to your child's chest, stomach, arms & thighs. This will usually happen up to four days after the rash on their cheeks.
Until the rash has faded.
