Persistent Symptoms in SARS-CoV-2-Infected and Non-Infected Household Members: A Prospective Cohort Study

This prospective study assessed the prevalence, type, and consequences of persistent symptoms following a nonhospitalized SARS-CoV-2 infection by comparing infected and noninfected children and adults of Dutch households. Two comparable prospective household studies were conducted during two pandemic phases. At baseline, all household members were tested for SARS-CoV-2 with 10 consecutive saliva samples during a 6-week period using RT-PCR. Questionnaires assessing persistent symptoms, health-related quality of life (HRQoL), anxiety, and depressive symptoms were collected at 6 and 12 months. Of the 297 included participants (median age 34 years, IQR 12–48), 201 (67.7%) tested positive for SARS-CoV-2. At 6 months, only one child reported persistent symptoms. SARS-CoV-2-infected adults (> 18 years) reported more pulmonary symptoms (15.2% vs. 3.4%, p = 0.023), and tended to report more fatigue (12.8% vs. 3.4%, p = 0.061) and exertion-related symptoms (8.8% vs. 1.7%, p = 0.107) compared to the negative adults. Adult participants with persistent symptoms reported decreased HRQoL and increased anxiety and depressive symptoms. This study found that SARS-CoV-2-positive adults tended to have higher prevalence of respiratory symptoms, fatigue, and exertion-related symptoms 6 months after SARS-CoV-2 infection, whereas children rarely reported persistent symptoms. Persistent symptoms were associated with a reduced HRQoL and increased anxiety and depression.
