To present a COVID-19 case series with clinical admission criteria to Intensive Care Unit. Patients information was obtained from medical records, and daily clinical evaluation whereas diagnosis was carried out through paraclinical studies in blood, urine, PCR and diagnostic images in 4 patients with different comorbidities and epidemiological link for the development of COVID-19. All four cases were managed with chloroquine 300 mg orally every 12 hours and azithromycin orally every 24 hours for 5 days without complications or associated toxicity.The case 1 developed multiple organ failure, including acute kidney injury with an ICU stay of 4 days before his death, while cases 2, 3 and 4 had a favorable evolution and were discharged fromthe ICU. Rapid multicenter studies are required to scientifically guide a better diagnostic and management approach, in the context of a disease with a clinical-epidemiological behavior that must be studied in depth and will probably take many lives. In addition, due to the absence of sufficiently rapid tests, the use of a classification based on the severity of radiological lesions called CO-RADS (Covid-19 Imaging Reporting and Data System) could be of great importance to install available pharmacological treatments early and early mechanical respiratory support.&nbsp
