Depends on what you want to believe I suppose. Initial data from Sweden shows kids are not good at spreading the virus.

Children are not sick
At the start of the epidemic, it was thought that children could in fact be asymptomatic carriers of the disease ... But Daniel Koch, the head of the OFSP crisis cell, said on Friday in a press conference that , according to the first serological tests - those looking for traces of antibodies - this does not seem to be the case.

But we must be careful, in the current circumstances, because there is currently no large-scale study, validated by the usual channels: Daniel Koch said to be based on the return of pediatricians and infectious disease specialists in the field.

Most of the infected children are not very sick: of the 3200 people hospitalized at the moment in Switzerland, only eighteen are less than ten years old. And while Switzerland records around 1,300 deaths, there have been none in this age group.

However, there have been some elsewhere in the world: one in Italy and one in France, in particular, but the number remains low.

It would be adults who infect children
According to some virologists, it seems that even when children are tested positive for the virus, their viral load, that is to say roughly the number of viruses circulating in their body, is often very low.

Which would explain why they are - still according to Daniel Koch - bad vectors of the disease. It seems that it is adults who infect children, not the other way around.

With age, the figures change, but remain low in adolescents: there have been 700 cases diagnosed in all in 10-19 year olds with still few hospitalizations and no deaths.

Hypotheses
For now, there are only hypotheses about why the virus has less control over very young people. The first is that their immune system is simply better. Perhaps also that it is more trained than that of adults, because it is more often in contact with pathogens and, in particular, benign coronaviruses, in the great broth of culture of nurseries and other school structures.

Finally, some specialists wonder if the vaccines against other diseases - which are very fresh in children - do not offer partial protection against Covid-19: either because the pathogens against which they are supposed to protect us a few things in common with the new coronavirus, either because they boost our general immunity, the one that fights intruders in all directions.

It kind of seems to fit the data we have so far unless there has been some kind of crazy spread form kids we still aren't aware of yet.
