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.
