Decentralized clinical study designed to collect further cough sounds, self-reportedsymptoms, and medical treatment questionnaires from participants enrolled on theCOVID-Cough Study ("Study 1").The aim of this further data collection study ("Study 2") is to: 1. develop an understanding of changes in cough sounds associated with COVID-19 and how they alter during the disease; 2. develop an understanding of other causes of COVID-19-like symptoms and their associated cough sound patterns; and 3. gain a broader understanding of the clinical outcomes of individuals who present for COVID-19 testing.
This study is designed to be administered in a decentralized manner to collect
self-reported COVID-19 symptoms, cough sample recordings and descriptions of recent
medical treatment to investigate the following:
1. Whether patterns unique to COVID-19 disease can be detected in cough sounds
collected over time;
2. The incidence of COVID-19 and other lung diseases within individuals who test
negative for COVID-19;
3. Whether existing machine learning algorithms can detect the presence of disease in
the lower respiratory tract in participants; and
4. Whether distinct cough sound patterns in COVID-19 disease are associated with the
requirement of medical treatment for COVID-19 disease. Through the administration of
Study 1, a list of potential participants will be created for whom the result of a
recent rt-qPCR COVID-19 test is known. Participants have been consented to allow for
outreach regarding further studies. Cough samples and answers to medical questions
have been collected from these individuals at the time of testing, and the aim of
Study 2 is to gather further cough samples and questionnaire answers over a period
of 25 days.
Diagnostic Test: Recordings of cough sounds from adults
Smartphone recordings of the cough sounds of participants who enrol in the study and
obtain a COVID-19 rt-qPCR result.
