How do I prepare for my child's return to school?
Text updated on 2021-05-03
This decision must take into account everyone's situation.
In some countries, parents can choose when their child can return to school after confinement. This decision must take into account the context of each person: risk of parents catching COVID-19 in their professional environment, presence of vulnerable persons in contact with the child, preventive measures taken in the school, the child's educational and psychological situation, means of transport used by the child, number of people with COVID-19 in the region, level of contamination and saturation of hospitals in the region, etc.
At this moment, here are some relevant observations that may help you make your decision:
- Children can get COVID-19. They usually have milder forms than adults, but some require hospitalization.
- Children can transmit coronavirus.
- Vaccinated people are much less likely to develop severe forms of the disease. It is not yet known whether they transmit the virus less.

In the Crépy-en-Valois high school (Oise, France), 38% of the students, 43% of the teachers, and 59% of the staff working in the school who were given a serological test were positive, confirming SARS-CoV-2 infections. The rate of secondary intra-familial transmission was estimated at 11% to parents and 10% to siblings.Fontanet, A., Shearer, L., Madec, Y., Grant, R., Besombes, C., Jolly, N., ... & Temmam, S.

Retrospective study of >40,000 cases COVID in China: the probability of dying from coronavirus if infected for people aged 80 years and over is estimated at 14.8% and for those aged 70-79 years at 8%. Beware, these figures are difficult to estimate: they are both overestimated because they do not take into account undetected infected people (not everyone is tested) and underestimated because some infected people have not yet died. An adult who reported having no pre-existing medical conditions ("co-morbidity") has a 0.9% chance of dying from COVID-19 if she/he catches it.Vital Surveys (2020).
