When should children stay home from childcare? Information for parents and childcare staff

Children who attend childcare centers are more vulnerable to more infections than other children. Usually, the child’s general health condition dictates the need to stay at home for a period, but some diseases may require longer absence to prevent the spread of infection to others.

Colds, sore throat and ear infections are almost twice as common among childcare children compared with children who are not. Gastrointestinal infections are almost three times as common. In addition, there may be frequent outbreaks of head lice, impetigo and various rashes diseases.

Spread of infections are primarily through direct or indirect contact between children.

When children do not need to stay home

For some diseases, there is no reason to keep the children at home. This may be because the disease is often transmitted before the symptoms occur, or the risk of infection is very small once the child has recovered, or the condition is mild and common.

Examples of these diseases include the fifth disease (erythema infectiosum), mouth sores, warts and foot-and-mouth disease.


When to keep sick children home from childcare

Experience shows that strict rules to keep sick children out of childcare have limited effect on the spread of infection. This may be partly because the disease is already infectious before the symptoms appear. Nevertheless, in various cases, a sick child should be kept at home for a period to prevent the spread of infections to other children.

For infectious disease, the child's general condition will often require some time at home and must always be based on the parental discretion. As a rule of thumb, the child should feel well enough to participate in normal activities in childcare and must be free from fever.

For many diseases, such as impetigo, it can be difficult to set an exact time frame for when the child can return to childcare. In such cases, physician or parental assessment is needed.

The following list covers the most common symptoms and diseases among children who attend childcare or lower grades in school.



A child normal temperature may vary. A raised temperature is considered to be higher than 37.5 °C in the morning and 38 °C at night. Children with fever should stay home until the fever has gone, essentially for their own comfort and also to avoid the spread of possible infectious disease.


Diarrhea with or without vomiting

Children with diarrhea can return to childcare two days after they have been symptoms-free. This also applies to children who use diapers. Children who normally tend to loose stools do not need to stay home. Parents shall decide whether the child has an abnormal diarrhea condition.

Suspected diarrhea infection through food (such as after travelling abroad), the child should be examined by a doctor and other children in the childcare should be monitored for symptoms.

Conjunctivitis (Pink eye)

There is no reason that children with mild to moderate conjunctivitis should be kept at home. Children who have severe conjunctivitis with abundant discharge should be kept home until the discharge has reduced, to prevent the risk of infections to other children. Severe conjunctivitis will often needed to be checked by a physician and the child's general condition will also largely determine the need to stay at home.

The parents should decide whether a child has conjunctivitis symptoms that must be examined by a doctor. Childcare staff cannot insist that a child with conjunctivitis symptoms must be examined or treated with eye drops before they can return to the kindergarten, but can discuss this with the parents if they are in doubt. If treatment is prescribed, the child may return to childcare the day after the treatment has begun.

EHEC infection
