The Association between Contact with Children and the Clinical Course of COVID-19.

We examined the association between contact with children and the clinical course of COVID-19 among COVID-19-positive adult patients. Participants completed a survey to assess demographics, medical information related to their COVID-19 diagnosis, contact with children at home and at the workplace. Patients were aged 45.68 ± 14.38 years, mostly female (72.1%), 842 were not hospitalized and 167 were hospitalized. At home, there were no differences between groups for the number of child contact hours or total child hours (hours × number of children) per week (s > 0.05). The number of children at home was greater among patients not hospitalized ( < 0.05), however this was no longer significant after controlling for covariates ( > 0.05). At the workplace, there were no differences between groups (all s > 0.05). Sub-group analysis found the proportion of patients that were treated in the intensive care unit (ICU) was greater among patients with no child contact ( < 0.05). A secondary analysis found that patients with no child contact had an increased likelihood of thromboembolism ( < 0.05) and a trend towards more overall COVID-19-related complications ( = 0.076). Overall, an association between contact with children and hospitalization was not found when adjusting for covariates. Sub-group analysis indicated a possible protective effect for more severe disease; however, these findings need further study.
