Risk Factors for Community- and Workplace Transmission of COVID-19

The project is an epidemiological observational study based on an electronic questionnaire on risk factors for COVID-19 in the community and healthcare setting.

Summary The data collected will identify real-life risk factors for getting the COVID-19 diagnosis. The Oslo University Hospital/University of Oslo web-based solution "nettskjema" will be used to collect data and consent forms. The impact of knowing the risk factors for COVID-19 is tremendous because it can enable governments to conduct more targeted public health measurements than today to reduce the spread of the virus. Detailed description Research into an ongoing COVID-19 outbreak is difficult because patients are isolated, and supplies of personal protective equipment (PPE) supplies are limited. The risk of transmission to study personal is non-negligible even when PPE is available. A study design based on an electronic questionnaire and consent from delivered from the Oslo University Hospital/University of Oslo, GDPR (General Data Protection Regulation) compliant "TSD" service has therefore been chosen. The study will be a case-control study based on a combined electronic consent form and questionnaire that the participants will fill in using a smartphone and electronic identification. The groups that will be included are: * Hospitalized and non-hospitalized patients/persons with COVID-19 at all stages of the disease and after the disease * Hospitalized patients without COVID-19 * Healthcare personal or other groups with an increased risk of COVID-19 * Healthy volunteers Participants may be followed with repeated questionnaires prospectively. Biological samples Biological samples may hold crucial information about the susceptibility to COVID-19 and for susceptibility to the progression of the disease. It is within the scope of the study to analyze such samples from a limited number of participants which will be asked to provide such samples or hospitalized patients that have surplus material. The material will be analyzed with non-genetic methods most suitable to provide such information.
