About COVID-19 among children and adolescents

The Norwegian Institute of Public Health monitors knowledge about the role of children in the spread of the disease. 

The combined knowledge about the virus indicates that children can be infected and develop symptoms, but to a lesser degree that unvaccinated adults. If they become ill, they usually have a milder disease course.

Since they have fewer symptoms than adults, they are less contagious. However, they can infect others, most commonly in their household.

Transmission in schools and childcare centres has contributed to a small extent in the spread of COVID-19 in society.

Adolescents get more symptoms of COVID-19 than children and are more contagious. In addition, many are naturally more social and have a larger network of contacts, and this normal lifestyle will involve the possibility of transmission.

During the pandemic, children and young people have been affected by strict infection control measures which have been introduced mainly to protect adults. Once a major part of the adult population is protected, outbreaks in childcare centres and schools will have fewer consequences and can be handled with less extensive measures. 

In July, the European Centre for Disease Prevention and Control published an updated risk assessment of COVID-19 among children and the school's role in the transmission, focusing on the increasing incidence of the Delta variant. ECDC points out that in areas where adults are mainly vaccinated, it is expected that an increasing proportion of all cases will occur among the child population. As children very rarely become seriously ill from COVID-19, ECDC points out that it is important to have infection control measures that are proportionate and adapted to the infection situation, and that it is important to maintain good preparedness in the school system for handling infection in the school year 2021/2022.

A large British study shows equally good effect on limiting infection by testing as with quarantine, including for the Delta variant. The risk of further transmission in school was very low, below 2 %. This is supported by unpublished Norwegian data.

Symptoms of COVID-19 in children

Children who get COVID-19 usually have a mild disease course. The symptoms are usually mild and short-lived, and can be difficult to distinguish from other respiratory tract infections. In most cases, children and adolescents who are ill will not have COVID-19, but other infections or conditions.

Examples of respiratory tract symptoms can be cough, sore throat, nasal congestion and runny nose. Children with COVID-19 may not have a fever and cough. The youngest children often do not complain about sore throats and body aches, but it is often noticed that they are getting sick when they do not want to join in with play or normal activity,  whine more than usual, or do not want to eat as much as normal. Some children may also have gastrointestinal symptoms, with abdominal pain, decreased appetite or diarrhoea.

When should you contact a doctor?

If you are worried about your child or adolescent, contact the health service. Medical consultation should not be delayed because of concerns for COVID-19 transmission.

In general, the younger the child is, the lower the threshold should be for contacting a doctor. As a general rule, this applies to children who are 2 years and younger, especially children aged under 6 months. 

When should children with respiratory tract symptoms stay at home and when can they return to school?

Now that the vast majority of the adult population has been vaccinated, and an increasing proportion of adolescents are vaccinated, strict measures are no longer necessary in society, and coronavirus infection can increasingly be treated like other respiratory tract infections.

It is up to the parents to decide whether the child should be tested for COVID-19. Children with respiratory symptoms do not necessarily need to be tested, unless a doctor has deemed it necessary. Some children, particularly in childcare age, may have a continuously runny nose. If they are otherwise in good form with no other signs of a recent respiratory tract infection, they do not need to stay home. If the symptoms get worse or more pronounced, the child should go home.

However, respiratory tract infections are most easily transmitted early in the course of the disease, so it is especially important that children with newly-arisen symptoms or who feel unwell stay at home. If symptoms are mild and disappear completely after one day, the child can return to childcare / school.

Otherwise, children can go to childcare / school when symptoms improve, their general condition is good, and have been fever-free for at least 24 hours without the use of antipyretics. The child can return even though he/she still has residual symptoms such as a runny nose, snot (regardless of the colour and consistency of the mucus), hoarseness or a slight cough. 

Children with known allergies where the symptoms are recognised as allergy problems may attend childcare / school as normal.

If you are concerned about your child, or if symptoms persist, consult a doctor.

Testing of children of primary school age and younger

Testing children can be difficult, and one must consider how important the test is seen in connection with how the child experiences being tested. It is important to ensure that children does not experience that the testing involves force, or is performed in a way that is perceived as traumatic for the child.

A low threshold for testing is still recommended with newly-arisen symptoms, but parents can consider whether their children should be tested or wait. Testing is recommended if  symptoms arise after close contact with a confirmed case of COVID-19 (last ten days).

If the child is a household member of someone who is infected, a 7 day testing regime is recommended, starting the day the infected person is isolated. If it is difficult to test the child, it is better to take a few tests than no tests and it is recommended that you try to carry out testing of children who are going to childcare or school. It is not necessary to test infants or toddlers who are not going to childcare and who are primarily with their closest caregivers. See Close contacts and isolation.

Both self-testing with rapid antigen tests at home or testing at a test centre can be used. With a positive self-test result, it is recommended to take a confirmatory sample at the test centre, and go into isolation.

When should adolescents with respiratory tract symptoms stay at home?

For adolescents with COVID-19 the symptoms resemble those in adults. Adolescents who have developed newly-arisen symptoms of respiratory tract infection should stay home from school and take a self-test or contact the local testing centre for a COVID-19 test. This also applies to adolescents with vague/mild symptoms.

Adolescents with known allergies where symptoms are recognised as allergy problems can go to school as normal.

Should children and adolescents be vaccinated with coronavirus vaccines?

The vaccines from BioNTech/ Pfizer and Moderna are approved for use for children from 12 years.

For children and adolescents, the risk of severe COVID-19 is low, even with underlying conditions. Vaccination will nevertheless help to protect the few who can become seriously ill if they become infected, in addition to reducing transmission in society.

The Government has decided that children and adolescents in the age groups 12-15 years and 16-17 years will be offered coronavirus vaccination based on advice from the NIPH.

More information

Children with chronic diseases have a low risk of severe COVID-19

The risk of severe COVID-19 disease course is very low, both among children and adolescents in general, but also among children and adolescents with serious and chronic diseases or conditions. In consultation with the Norwegian Paediatric Association, the Norwegian Institute of Public Health considers that the vast majority of children and young people with chronic diseases and conditions can go to childcare and school as normal.

Multi-inflammatory syndrome in children, MIS-C 

Some countries have reported an inflammatory condition after COVID-19 among children and adolescents, known as MIS-C (multi-inflammatory syndrome in children) or PIMS (paediatric inflammatory multisystem syndrome temporarily associated with COVID-19). The condition is rare, but serious. In Norway the condition has occurred in less than 1 in 1,000 children and adolescents who have been diagnosed with COVID-19. When treated for this syndrome the prognosis is good.

Long-term effects of COVID-19 in children

So far, studies show that there is little risk of long-term effects of mild COVID-19 among children and adolescents, even though there is still a lack of knowledge. Studies of children and adolescents that include control groups have shown that both those who are diagnosed with COVID-19 and those who are not diagnosed with COVID-19 may have symptoms after a mild infection. Norwegian registry data show that for mild COVID-19 in children and adolescents, few need contact with the health service after undergoing infection. The analyses included all tested children and adolescents under the age of 18 in Norway, who were compared with randomly selected controls, approximately 700,000 people in total. Danish registry data show similar findings.

Children staying in several homes

Many children have several homes. Most often, these are children with guardians who have two different households after a break-up, but they can also be children and adolescents who have different forms of relief families or have part-time stays in care homes.

The main rule is that planned meetings can be maintained as agreed. 

Care for children when several people in the household are ill

It is important that the child /adolescent's need for care is taken care of, even if their guardian has COVID-19. Similarly, if the child has COVID-19, they must receive adequate care and attention from parents or others, even though this may mean that it is not possible to keep a distance. If caregivers are ill and unable to care for children for whom they are responsible, the municipal health services must be informed to implement relief from child welfare or others, as in other situations where caregivers are ill.

Follow-up at public health clinics, school health service and other health services

The municipalities should ensure that health services offered to children and adolescents are adequate. The health station and school health services should run as normal, with basic infection control measures.

Childcare centres, schools and after-school programmes

Daily life, events, leisure activities and other gatherings in schools and childcare centres in most municipalities can take place as normal.
