Quick answer
What is Slapped cheek syndrome?
Slapped cheek syndrome (fifth disease), caused by parvovirus B19, is a common viral infection, mainly in children. It often begins with mild cold-like symptoms and fever, followed by a distinctive bright red rash on both cheeks (as if the child has been slapped), and sometimes a lacy rash on the body and limbs.
- How it is treated: For most children, no specific treatment is needed and the infection is managed with rest, fluids and simple measures for fever while it settles.
- Self-care: Rest, fluids and simple fever relief help recovery.
- When to seek help: See a GP if you are pregnant and have been in contact with slapped cheek syndrome, if you have a blood disorder or weakened immunity and become unwell, or if a child is very pale, very tired or breathless.
What it is
Slapped cheek syndrome (fifth disease), caused by parvovirus B19, is a common viral infection, mainly in children. It often begins with mild cold-like symptoms and fever, followed by a distinctive bright red rash on both cheeks (as if the child has been slapped), and sometimes a lacy rash on the body and limbs. In most children it is mild and clears on its own. However, it needs particular care in pregnant women (as it can occasionally affect the baby), in people with certain blood disorders (such as sickle cell disease), and in those with weakened immune systems, where it can cause a drop in red blood cells. Adults may get aching joints.
How it is treated
For most children, no specific treatment is needed and the infection is managed with rest, fluids and simple measures for fever while it settles. By the time the rash appears, the child is usually no longer infectious, so they do not generally need to stay off school. The main considerations are the higher-risk groups: pregnant women, people with certain blood conditions and those with weakened immunity should seek advice if exposed or unwell, as they may need monitoring or specific care. Otherwise, reassurance is the mainstay.
