People with young children at home may be less likely than others to contract severe Covid-19. At least, that’s what a study published in the journal Proceedings of the National Academy of Sciences In the 27th of this article, adults who do not live with children have a 49% increased risk of hospitalization.
The theory is that kids bring home a cold one from nursery school or school, and this mild infection may offer some protection against severe Covid-19. To better understand this relationship, a team of scientists combed through the medical records of more than 3 million patients seen at a California hospital from February 2019 to January 2021.
By analyzing patients with Covid, researchers found that adults without children had a 49% greater risk of needing hospitalization and a 76% greater risk of ending up in the intensive care unit, compared to patients with 5-year-olds. or less.

“Having young children does not provide absolute protection. Our study only points to this effect. It is a small piece of a larger puzzle that scientists are working on. Why do some people get severe Covid-19 while others do not? The issues around something are very complex,” the study says. .
However, the article’s authors point out an important limitation: the research was conducted before mass vaccination against COVID-19. Furthermore, it is unclear whether any immunity conferred by the common cold can apply to all variants, especially the more contagious current strains, which include the BA.5 and BA.4 sub variants of μM.
