AbstractInfection with the SARS coronavirus type 2 (COVID-19) has a variety of presentations, with little data on the evolution of affected patients in Argentina. This is a retrospective and observational study of patients with virological confirmation of coronavirus treated during the months of March to May in a private third-level university hospital in Buenos Aires. O ne hundred and fifty-five adult patients were included, of which 30.3% attended only for a swab; 59.4% were admitted to the hospital and 10.3% were hospitalized at home with daily telephone follow-up. Fifty-four point two percent of participants were women and the median age was 35 years (ICQ 29 to 50). About 59.3% of patients had some risk factor, including age (65 years old or more), underlying chronic disease, were health workers or personnel/residents in a nursing home. The most frequent symptom was fever (75.9%), followed by cough (65.7%), and odyno phagia (48.2%). Globally, 93.5% experienced some symptoms while 17.6% of the participants presented some symptoms but without fever. Chest tomographies were performed to 5 patients. Their chest radiograph was normal or non-diagnostic. Fourteen patients required intensive therapy and 6 of them required mechanical ventilation, 4 of them died. The remaining 2 patients were referred to chronic care centers. No patient with home hospitalization required admission to hospital or died. While this observation is encouraging, it will need to be confirmed with new studies.
