The SARS-COV2 Pandemic has required the emergency departments to focus their attention and care to COVID-19-diagnosed patients over patients with other pathologies. Descriptive study of patients attended in the resuscitation room between 1st of March and 31st May 2019 and compared to the same period in 2020. We include all the patients attended were included in the study and their clinical variables evaluated and their diagnosis at discharge. Six hundred and fifty-nine patients were attended in 2019 and 384 in 2020. There were no differences between age and gender. In 2019, 83.2% of the cases attended had a cardiac pathology, followed by neurological pathology and traffic accidents. This data is also significant since in the same period of 2020 cardiac pathology fell to 8.3%. The COVID pandemic has reduced patients attended at resuscitation room, and especially cardiovascular ones. These are preliminary results and more studies should be done to confirm or to study this trend.

Objective: We aimed to assess the prevalence and clinical characteristics of SARS-CoV-2 reinfections in a Spanish region. Methods: This is a retrospective observational study in all patients with SARS-CoV-2 infections in the Lleida health region from 1 March to 30 November 2020. Reinfections were classified as patients with positive SARS-CoV-2 PCR tests separated by at least 90 days plus a negative test result between both infection episodes. Primary and secondary outcomes: The primary outcome was the percentage of SARS-CoV-2 reinfections among all SARS-CoV-2 infections detected during our study period. Secondary outcomes were the clinical and sociodemographic characteristics of patients with SARS-CoV-2 reinfections. Results: Of the 27,758 patients diagnosed with SARS-CoV-2 infection in the study period, 14 were identified as coronavirus reinfection (0.050%). Of the reinfected sample, 12 patients (85.7%) were women. The median age was 41.5 years. Two patients died in the second coronavirus episode. Conclusion: The reinfection rate of SARS-CoV-2 in the Spanish region Lleida was relatively low during the observational period in 2020 (less than 1%). These data are in line with the notion that previous SARS-CoV-2 infections may offer a significant protection by so called natural immunity.
