Participants Diagnosed with COVID-19
Participants were previously enrolled in a RO7496998 (AT-527) study
|
- COVID-19 Symptoms Assessment through the COVID-19 Symptom Diary (Items 1-14) [ Time Frame: Up to 6 months ]COVID-19 symptoms will be evaluated using the COVID-19 Symptom Diary (items 1-14). The severity of each COVID-19 symptom will be recorded on a Likert scale (i.e none/mild/moderate/severe).
- Dyspnea Symptoms Assessment through the Patient Reported Outcomes Measurement Information System (PROMIS) - Dyspnea Questionnaire [ Time Frame: Up to 6 months ]The PROMIS-Dyspnea Questionnaire will be used to evaluate the impact of Dyspnea on specific activities. The severity of impact on each activity will be recorded on a Likert scale with a recall period over the last 7 days (i.e no shortness of breath, mild/moderate/severe shortness of breath or not applicable)
- Respiratory Symptoms Assessment through the St. George's Respiratory Questionnaire (SGRQ) [ Time Frame: Up to 6 months ]The SGRQ is a 50-item respiratory-specific health-related quality of life instrument that measures health impairment. The questionnaire contains 3 domains: symptoms, activity, and impacts. Items were assessed on various response scales, including a 5-point Likert scale and True/False scale. The SGRQ had a recall specification of 4 weeks.
- Proportion of Participants with COVID-19 Related Medically-Attended Visits [ Time Frame: Up to 6 months ]COVID-19-related medically-attended visits are defined as hospitalization, ER visit, urgent care visit, physician's office visit, or telemedicine visit with the primary reason for the visit being COVID-19 or COVID-19-related symptoms.
- Proportion of Participants with Death Attributable to Progression of COVID-19 [ Time Frame: Up to 6 months ]
- Proportion of Participants Re-Infected with Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) [ Time Frame: Up to 6 months ]
- Proportion of Participants with any Post-Treatment Infection [ Time Frame: Up to 6 months ]
- Frequency of COVID-19 Related Complications [ Time Frame: Up to 6 months ]Examples of COVID-19 related complications include death, hospitalization, radiologically confirmed pneumonia, acute respiratory failure, sepsis, coagulopathy, pericarditis, myocarditis and cardiac failure.
- Proportion of Participants with Adverse Events (AEs) and Serious AEs (SAEs) [ Time Frame: Up to 6 months ]Event severity will be determined according to National Cancer Institute Common Terminology Criteria for Adverse Events Version 5 (NCI CTCAE v5.0)
