Role of Children in Transmission of COVID-19 to Immunocompromised Patients

This is a study of immunosuppressed individuals living in households with and without children to assess the role of household contact with children in the transmission of SARSCoV-2 to immunocompromised individuals. Through careful collection of epidemiological data in combination with biological specimens, risk factors for SARS-CoV-2 in immunocompromised individuals will be identified. During the initial visits, informed consent will be obtained and consented participants will complete an initial questionnaire and provide biological specimens including nasal swabs, saliva and blood. Thereafter, participants will complete at-home saliva collections and questionnaires on a weekly basis for 6 months. If our research-use only SARS-CoV-2 test is positive, participants will be referred immediately for medical attention and will be followed every 3 days with nasal swabs and saliva samples and weekly blood specimens and optional rectal swabs or fresh stool collection. Additionally, participants will be contacted by telephone at 1 year for follow-up.
