简要总结
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.
- a swab will be inserted deep into the back of the nose and
- a swab will be inserted to the middle of your nose.
Participation lasts 3 to 4 weeks.
详细描述
Study Description:
This is a prospective longitudinal cohort study of individuals who have recently tested positive or are highly suspected to be positive for severe acute respiratory syndrome-coronavirus-2 (SARS-CoV- 2) infection. The aim is to correlate results of reverse transcription-polymerase chain reaction (RT-PCR) using various sample types, assays, and culture. We will enroll individuals with at least one recent positive RT-PCR test result (confirmed cases) and individuals whose referring physician highly suspects current or recent SARS-CoV-2 infection but the individual has not had access to testing (probable cases). At baseline, participants will undergo collection of nasopharyngeal (NP) swabs, saliva samples, and midturbinate swabs for SARS-CoV-2 RT-PCR and culture, and blood draw for antibody assay. Subjects enrolled as probable cases who have a positive baseline RT-PCR result and all subjects enrolled as confirmed cases (regardless of baseline result) will be followed with serial screenings until they have 2 consecutive negative RT-PCR test results.
Objectives:
Primary Objective:
Correlate results of SARS-CoV-2 RT-PCR using various sample types, antibody assays and culture.
