Official title
Send-In Sample Collection for Comprehensive Analyses of Innate and Adaptive Immune Responses During Acute Infections With, and Convalescence From, Emerging or Re-emerging Respiratory Viruses
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19). The global outbreak of COVID-19 is a major public health problem. COVID-19 causes a wide range of symptoms. These symptoms range from mild breathing problems to life-threatening problems or death. Some people have no symptoms. This study aims to learn how acute and late immune responses to COVID-19 lead to different outcomes. The immune system is the body s defense against germs, including viruses, that invade the body. Objective: To characterize the immune responses during and after SARS-CoV-2 infection and determine if there is any relationship to clinical course and outcome. Eligibility: People ages 0 99 who have confirmed or suspected SARS-CoV-2 infection, people who are not infected despite heavy exposure, and relatives of enrolled participants. Design: This is a sample collection protocol to receive send-in biological specimens for exploratory studies, including gene testing. Participants will not be seen at the NIH for study visits. Study staff will talk with participants health care providers to screen them for the study. Participants enrolled into the protocol will send samples and clinical information at least once and more often if the participant has COVID-19. All participants will provide blood samples and possibly stool. We may also ask for left over specimens from any medical procedures completed as part of medical care. The study staff will also request participants health care providers to complete a survey to collect demographic and medical data. Some of this information may need to be provided directly by the participant. Pregnant individuals are invited to participate and may be asked to give cord blood samples after delivery. Study findings that affect participants health may be shared with their health care provider. Depending on findings, participants may be contacted to take part in other NIH studies.
