Overview
Slapped cheek syndrome is a common, mild viral illness in children that causes a bright red rash on the cheeks, giving the appearance of having been slapped. A lacy rash may later spread to the body and limbs. Most children feel well and recover without treatment, though the virus carries particular risks during pregnancy.
Symptoms
- Bright red rash on both cheeks
- A lacy or blotchy rash spreading to the arms, legs, and trunk
- Mild fever, runny nose, or sore throat before the rash
- Tiredness and sometimes joint aches
- Rash that may come and go for weeks with heat or sunlight
Causes & risk factors
- Infection with parvovirus B19
- Spread through coughing, sneezing, and respiratory droplets
- Most contagious before the rash appears
- Common in outbreaks among school-age children
Treatment & self-care
Care is supportive — rest, fluids, and comfort measures while the rash fades on its own. A licensed clinician should be consulted if a child has an underlying blood disorder or weakened immune system, and any pregnant person exposed to the virus should seek prompt advice.
See a doctor urgently if
- A pregnant person has been exposed to or developed the illness
- Your child has a blood disorder such as sickle cell disease or thalassaemia
- Your child looks very pale, unusually tired, or breathless
- Your child has a weakened immune system
- Fever is high or your child seems very unwell
