The SARS-CoV-2 pandemic has had a substantial impact on public health, economies and societies worldwide. From the early days of the pandemic, it was clear that joint research efforts of various disciplines would be necessary to tackle challenges posed by the virus and support policy and decision-making in Switzerland and worldwide. To this end, cohort studies emerged as valuable tools to assess the health, social and economic consequences of the pandemic.
The Zurich SARS-CoV-2 Cohort study was conceived in mid 2020 and set out to gather critical data to inform public health measures aiming to mitigate the spread of SARS-CoV-2 and to limit its impact on those affected. The study was established in close collaboration with the Department of Health of the Canton of Zurich, Switzerland, and brings together the expertise of epidemiologists, immunologists, and infectious disease specialists to answer questions on various aspects of SARS-CoV-2 in order to better understand its epidemiology and long term effects. It is an ongoing, population-based, longitudinal cohort of randomly selected individuals infected with SARS-CoV-2, including a complementary case-ascertained study of their close contacts in the Canton of Zurich. Comprehensive assessments regarding the longer-term health and medical consequences (i.e., Long Covid or post COVID-19 condition), re-infections, breakthrough infections following vaccination, as well as humoral and cellular immune responses, are conducted regularly up to three years after SARS-CoV-2 diagnosis.
Among others, the study has the following three main objectives:
