简要总结
The type and number of chemicals in exhaled breath are different in people with infection as compared to those without infection. In this study, the breath of people with and without COVID infection will be measured. Changes in the amount and type of chemicals in breath will be used to determine if an individual does or does not have COVID infection. If the measurements of breath are a reliable measure of COVID infection, this device may be used to rapidly screen people who are attending large public events (for example, music concert or baseball game) to minimize the spread of COVID at the event.
详细描述
N5 Sensors has developed a device that can measure chemical concentrations at parts-per-billion levels (for example, 10 molecules in one-billion molecules is 10 parts-per-billion). This device will be used to measure a variety of chemicals in the exhaled breath of human volunteers. The measured chemicals have been selected based on their presence in the breath of subjects with COVID infection. In addition to measuring breath, samples of mucus from the nose of these same subjects will be collected. These nasal samples will be evaluated to determine the presence of the COVID virus and of COVID infection. Changes in chemicals in the breath will be compared to the presence of COVID or to infection with COVID. This comparison will determine if measurement of breath can be used as a quick and simple measure of COVID infection.

结局指标
主要结局
Exhaled chemicals in breath will be compared with COVID status
时间窗: On the day of enrollment, all measurement will be made over the course of 2 hours.
Between subjects with and without COVID, changes in the chemical composition of exhaled breath are correlated with markers of COVID infection: 1) antigen testing of nasal mucous sample and 2) RT-PCR testing of nasal mucous sample.
Assessment of COVID status using nasal swab.
时间窗: On the day of enrollment, all measurement will be made over the course of 2 hours.
Two nasal swabs will be collected for each subject. One nasal swab will be evaluated by antigen testing and the other sample will be analyzed using RT-PCR.
Measurement of chemical composition in exhaled breath
时间窗: On the day of enrollment, all measurement will be made over the course of 2 hours.
Each subject will provide two breath samples. Each sample will be analyzed by the RISE device.
