Is the 14-day COVID-19 symptom-based test an accurate screening test to clear persons to return to work?
- Key Finding: Among asymptomatic individuals with possible exposure to COVID-19, the sensitivity of detecting active COVID-19 infection with 14-day symptom-based test is 92.8% and specificity is 98.3%. The 14-day symptom-based test can be used for clearing workers to return to work.
What are the signs and symptoms of COVID-19 patients?
- Key Finding: Systematic reviews of observational studies have shown that the most common symptoms of COVID-19 are fever, cough and fatigue/myalgia
Should Chest X-ray be used in the diagnosis of COVID-19?
- Key Finding: While Chest x-ray is readily available and may precede RT-PCR diagnosis of COVID-19, it has low sensitivity especially early in the disease and abnoralities are non-specific.
Should IgM/IgG rapid test kit be used in the diagnosis of COVID-19?
- Key Finding: Current evidence does NOT support use of IgM/IgG rapid test kits for the definitive diagnosis of COVID-19 in currently symptomatic patients.

Through the volunteer work of more than 50 EBM practitioners, methodologists and students from the UP Institute of Clinical Epidemiology and Asia-Pacific Center for Evidence-Based HealthCare, the Philippine Society of Microbiological and Infectious Diseases (PSMID) had graciously agreed to host these rapid evidence reviews on COVID19. The aim is to retrieve, appraise, summarize and update the available evidence on COVID-related management, to assist the frontline health workers, local policymakers and government officials in their evidence-based critical decision-making.
The reviews should not replace individual clinical judgement and the sources cited should be checked. The views are not a substitute for professional medical advice. The views expressed represent the views of the authors and not necessarily those of their host institutions. This may change as new evidences emerges.
