The patients were isolated at home and monitored daily.</p><p><strong>Results: </strong>Based on the World Health Organization classification, 79% of studied patients had mild illness while 20.5% had moderate illness. The initial symptoms included cough (51.7%), fever (50.8%), fatigue (45.9%), sore throat (41.1%), dyspnea (35.2%), and headache (34%); 25.2% patients had prolonged symptoms (≥ 21 days). Dyspnea was the most frequent (15.5%) long-term symptom. Age, co-existing diabetes, and COVID-19 infection with moderate severity, were associated with the need for hospitalization. We compared patients with COVID-19 infection who required hospital admission (n = 37) versus patients who continued in home isolation (n = 574). High neutrophil/lymphocyte ratio, transaminases, and ferritin significantly correlated with the need for hospitalization. 18.9% of the patients who required hospital admission had diabetes. Multivariate analysis described age and diabetes as independent predictors of disease severity. Age and high neutrophil/lymphocyte ratio were independent predictors of hospital admission.</p><p><strong>Conclusions: </strong>Telemedicine is effective in-home management of mild/moderate COVID-19 patients, which may ease the pressure on the healthcare system, even beyond the pandemic.</p>","PeriodicalId":49160,"journal":{"name":"Journal of Infection in Developing Countries","volume":"18 9.1","pages":"S176-S183"},"PeriodicalIF":1.4,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142584858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
