Objective: Know the number and percentage of chest X-rays (CXR) referred to a Primary Care Imaging Center and Primary Care Emergency Center to rule out lung involvement due to SARS-Cov-2 from March 16, 2020 to March 15, May 2020, in an urban health area of about 400,000 reference population inhabitants.To determine the percentage of cases suggestive of pulmonary involvement due to SARS-Cov-2 CXR and the percentage of cases without pulmonary involvement of the total CXR derived in the reference population from March 16, 2020 to May 15, 2020. Material and methods: Design: observational descriptive study.CXR is studied with the following criteria: The Radiological Criteria to classify probable pulmonary infection by SARS-Cov-2 (RxT (+)) are: 1-focal opacity, 2-faint focal opacity, 3-faint diffuse increase in density, 4-focal or diffuse interstitial pattern, 5-Focal or diffuse interstitial alveolus pattern. (14) Results and conclusions: Maintain CXR as a useful screening method in the middle stages of the disease, when CXR is more sensitive to detect lung involvement due to SARS-Cov-2.Our graph of affectation by SARS-Cov-2 does not present assessable differences with the expected curve in an epidemic.
