Overview
Slapped cheek syndrome, also known as fifth disease or erythema infectiosum, is a common childhood infection caused by parvovirus B19. It gets its name from its most distinctive symptom: a bright red rash on both cheeks that looks as though the child has been slapped. The infection is most common in children aged between 6 and 10 years, though adults can also be affected. According to the NHS, slapped cheek syndrome is usually a mild illness that clears up on its own within one to three weeks without the need for specific medical treatment. However, visits to the NHS slapped cheek page have risen by over 200 per cent in recent months, reflecting growing concern among parents during the current outbreak. The infection spreads through respiratory droplets from coughs and sneezes, and a person is most contagious before the rash appears, which makes it difficult to prevent spreading.
In children, the first signs of slapped cheek syndrome are usually mild cold-like symptoms including a slight fever, runny nose, sore throat, and headache. These initial symptoms appear around one to two weeks after infection. A few days later, the characteristic bright red rash appears on both cheeks, giving the condition its name. A lighter, lace-like rash may then develop on the body, arms, and legs, which can be slightly itchy. In adults, the rash may be less prominent or absent altogether, but joint pain and stiffness are common, particularly in the hands, wrists, knees, and ankles. This joint discomfort can last for several weeks or even months. Most people recover fully without complications. However, the NHS advises seeking medical advice if you are pregnant and have been in contact with someone who has slapped cheek, if your child has a blood disorder such as sickle cell disease, or if your immune system is weakened.
One of the biggest concerns for parents and families is the risk that slapped cheek syndrome poses during pregnancy. While the infection is usually harmless for most people, parvovirus B19 can occasionally cause serious complications if a pregnant woman becomes infected, particularly during the first 20 weeks of pregnancy. In rare cases, the virus can affect the unborn baby by causing severe anaemia, a condition called hydrops fetalis, or in very rare circumstances, miscarriage. It is important to stress that the overall risk remains low. According to NHS guidance, most pregnant women who come into contact with slapped cheek will already be immune from a previous infection, and around 60 per cent of adults in the UK have had the virus at some point. If you are pregnant and think you may have been exposed, you should contact your GP or midwife as soon as possible. A blood test can confirm whether you are immune or have a current infection, and further monitoring may be arranged if necessary.
Hand, foot and mouth disease is a common viral infection caused by the coxsackievirus. It is most frequently seen in children under the age of five, although older children and adults can also catch it. The condition is not related to foot and mouth disease that affects animals. According to the NHS, hand, foot and mouth disease is generally a mild, self-limiting illness that usually clears up within seven to ten days without the need for medical treatment. However, it is highly contagious and spreads easily through nurseries, schools, and households. The virus is transmitted through direct contact with the fluid from blisters, respiratory droplets from coughs and sneezes, and contact with contaminated surfaces or objects. NHS page visits for hand, foot and mouth disease have risen by nearly 50 per cent, reflecting increased outbreaks across the UK.
The symptoms of hand, foot and mouth disease typically develop three to five days after exposure to the virus. Early signs include a sore throat, high temperature, loss of appetite, and general irritability in young children. Within a day or two, painful mouth ulcers usually appear on the tongue, gums, and inside of the cheeks, making eating and drinking uncomfortable. A non-itchy rash of small red spots then develops on the palms of the hands, soles of the feet, and sometimes the buttocks and legs. These spots may turn into small blisters that can be mildly painful. In most cases, the symptoms are mild and resolve on their own. However, the mouth ulcers can be particularly distressing for young children and may cause them to refuse food and drink. The NHS recommends keeping your child hydrated with regular small sips of water and offering soft, cool foods that are easy to swallow. Avoid acidic or spicy foods that may irritate the ulcers further.
Both slapped cheek syndrome and hand, foot and mouth disease are highly contagious and spread easily in settings where children are in close contact, such as nurseries, schools, and playgroups. Slapped cheek spreads through respiratory droplets and is most contagious in the early stages before the rash appears, making it very difficult to contain. Hand, foot and mouth spreads through direct contact with blister fluid, saliva, nasal secretions, and faeces, as well as through contaminated surfaces. Good hygiene practices are the most effective way to reduce the risk of spreading both infections. These include washing hands frequently with soap and warm water, especially after nappy changes and before preparing food, using tissues when coughing or sneezing and disposing of them immediately, regularly cleaning and disinfecting toys, surfaces, and shared objects, avoiding sharing cups, cutlery, and towels, and keeping infected children at home until they feel well enough to return to normal activities. The NHS handwashing guide provides clear advice on effective hand hygiene techniques.
Both slapped cheek syndrome and hand, foot and mouth disease are caused by viruses, which means antibiotics will not help. Treatment focuses on managing symptoms and keeping your child comfortable while the infection runs its course. For both conditions, you can give children's paracetamol or ibuprofen to reduce fever and relieve pain, following the dosage instructions on the packaging or asking your pharmacist for guidance. Encourage plenty of fluids to prevent dehydration, especially if mouth ulcers are making eating and drinking difficult. Cool, soft foods such as yoghurt, ice lollies, and soup can help soothe mouth pain. Calamine lotion may ease itching from the rash. You should seek medical advice if your child is under three months old with a temperature of 38 degrees or above, if they are not drinking enough fluids, if symptoms are getting worse rather than better after seven to ten days, if you are pregnant and have been exposed to either infection, or if your child has a weakened immune system or a blood disorder. You can call NHS 111 for urgent advice at any time.
