The primary aim of this single-center prospective observational study is to establish how immune responses to SARS-CoV-2 or to cross-reactive viruses correlate with the virological and clinical characteristics of SARS- CoV-2-infected patients and their exposed household contacts. Through iterative sampling, the viral kinetics of at least 50 infected patients will be evaluated in relation to symptom severity and innate and adaptive immune responses, while their household contacts will be observed for viral detection and immune responses. Patients and contacts will be followed for 8 and 2 weeks, respectively. The study will include a maximum of 250 participants.
This single-center prospective observational study will examine immune responses to to SARS-CoV-2 and how they correlate with its virological characteristics and clinical manifestations in infected patients. Household contacts will also be included so that early immune responses and viral kinetics can be captured. Patients and contacts will be followed for 8 and 2 weeks, respectively. The study will include a maximum of 250 participants.
