How do I prepare for my child's return to school?
Text updated on 2020-05-09
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 should take into account the situation of each individual: the risk of parents catching the COVID-19 child in their professional environment, the presence of vulnerable persons in contact with the child, preventive measures taken in the school, the child's educational and psychological condition, the means of transport used by the child, the level of contamination and saturation of hospitals in the area, 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. Several cases of child-to-parent transmission have been documented. It is not yet known how common these cases are because there have been no large-scale published studies.
- A person 80 years of age and older has on average 14% chance of dying from COVID-19 if they catch it. A person 70-79 years old has a 3-8% chance of dying from it. Similar figures have been measured in China, Europe and the United States.
- On average, an adult who reports having no pre-existing medical conditions ("co-morbidity") has a 0.9% chance of dying if he or she develops the diseaseCOVID-19. Certain pre-existing conditions (cardiovascular disease, diabetes, etc.) put individuals at a higher risk of dying from COVID-19.
- The risk of transmission of HIV COVID-19 within the family home has been estimated at 15% in China (it should be remembered that barrier gestures are generally better respected there than in Western countries). Estimates of the risk of transmission appear to be similar for Western countries.

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).
