Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: People who have had contact with a person with a known SARS-CoV-2 infection are being told to self-quarantine for 14 days. This is done to avoid potential virus spread. But the actual time it takes for a person to develop an infection after being exposed to the virus is not well known. The proper quarantine time could be less or more than 2 weeks. Researchers hope this study can be used to help improve public health guidelines for quarantines, social distancing, and returning to work after a possible SARS-CoV-2 exposure. Objective: To better understand how long it takes a person to develop (or not develop) an infection with the SARS-CoV-2 virus after they have had contact with a person who has a confirmed infection. Eligibility: NIH staff members age 18 and older who had recent contact with a person who has a SARS-CoV-2 infection Design: Participants will have 3 study visits at the NIH Clinical Center. They may be asked to have an extra visit depending on the test results at the third visit. At each visit, participants will give a blood and saliva sample. It will be used to test for SARS-CoV-2 antibodies. Their temperature will be taken. They will complete a short survey to collect data about possible COVID-19 symptoms. At the first visit only, they will also complete a survey that asks about their recent social contacts. Two types of nasal samples will be collected at each visit. These samples will be tested for the SARS-CoV-2 virus. 1. a swab will be inserted deep into the back of the nose and 2. a swab will be inserted to the middle of your nose. Participation lasts 3 to 4 weeks.
