Roseola commonly affects children aged between six months and two years, and 95 per cent of children have been infected with it by the age of two. Roseola is contagious before the symptoms appear, so it is difficult to prevent its spread to others. If your child has roseola, they may have a sudden high temperature, which usually lasts between three to five days.
It appears on the body and spreads to the arms and legs; it is rarely seen on the face. The rash generally lasts for two days and turns white blanches when pressed.
Some children get a high temperature but no rash. Rarely, the temperature spikes quite suddenly and can lead to a febrile convulsion a seizure, or fit.
While this is distressing for parents to witness, it is not usually serious. See our fact sheet Febrile convulsions. Roseola is contagious, meaning it can be spread from one person to another. It is spread by the fluids that are coughed or sneezed into the air. Once your child has symptoms, they are no longer contagious. There is no known way to prevent the spread of roseola and there is no vaccine. Thorough hand hygiene is the best way to help reduce the spread of the virus.
If your child is unwell with a fever and a skin rash small bright red spots or purple spots or unexplained bruises that does not turn to skin-colour blanch when you press on it, this may be a sign of meningococcal infection see our fact sheet Meningococcal infection. Children with roseola are only contagious before their symptoms appear, so once you realise they have roseola they can no longer spread the virus to other children. If your child is feeling well enough, because her symptoms are very mild, it will be OK to send her to child care.
However, it is important for them not to overexert themselves or be around others while they are still considered to be contagious. Children can return to normal activities once they have been fever-free for 24 hours and do not have any other significant symptoms. There is no vaccine available to prevent roseola. Prevention involves limiting exposure to infected people. For this reason, it is important that children with roseola do not come into contact with other children until their fever has broken.
People who have contact with roseola should wash their hands frequently to avoid passing the virus on, especially to someone who does not have the antibodies to fight it. It is also a good idea to wipe down household surfaces regularly with antimicrobial sprays.
People can reduce the risk of infection by teaching children hygienic practices, such as ensuring they sneeze and cough into tissues and immediately dispose of the tissue afterward.
Also, it is best to avoid allowing them to share cups, plates, or utensils with others to reduce their exposure to infected saliva. Roseola is usually not a serious illness. It usually resolves on its own, without complications, within a week or so. With home treatment, symptoms can be managed, and discomfort can be reduced. Also, the vast majority of children acquire roseola before kindergarten, which protects them against an acute repeat infection later in life.

Image credit: Emiliano Burzagli, , August What are the causes? Risk factors. Occasionally a child with roseola experiences a seizure brought on by a rapid rise in body temperature.
If this happens, your child might briefly lose consciousness and jerk his or her arms, legs or head for several seconds to minutes. He or she may also lose bladder or bowel control temporarily. If your child has a seizure, seek emergency care. Although frightening, fever-related seizures in otherwise healthy young children are generally short-lived and are rarely harmful. Complications from roseola are rare.
The vast majority of otherwise healthy children and adults with roseola recover quickly and completely. Roseola is of greater concern in people whose immune systems are compromised, such as those who have recently received a bone marrow or organ transplant.
They may contract a new case of roseola — or a previous infection may come back while their immune system is weakened. Because they have less resistance to viruses in general, immune-compromised people tend to develop more-severe cases of infection and have a harder time fighting off illness. People with weak immune systems who contract roseola may experience potentially serious complications from the infection, such as pneumonia or encephalitis — a potentially life-threatening inflammation of the brain.
Because there's no vaccine to prevent roseola, the best you can do to prevent the spread of roseola is to avoid exposing your child to an infected child. If your child is sick with roseola, keep him or her home and away from other children until the fever has broken. Most people have antibodies to roseola by the time they're of school age, making them immune to a second infection.
Even so, if one household member contracts the virus, make sure that all family members wash their hands frequently to prevent spread of the virus to anyone who isn't immune.
Adults who never contracted roseola as children can become infected later in life, though the disease tends to be mild in healthy adults. However, infected adults can pass the virus on to children. Mayo Clinic does not endorse companies or products.
