Background: Severe acute respiratory illness caused by SARS-CoV-2 has been a health emergency of great concern in the year 2020. This study was undertaken to identify characteristics of hospitalized patients with Coronavirus Disease 19 (COVID-19) and hypoxia in the form of disease course and outcome with special reference to the presence or absence of comorbidities. Materials and Methods: A prospective observational study was conducted at a tertiary hospital recognized as Dedicated COVID Hospital during the period of June 2020 to September 2020. The study included a total of 249 patients of COVID-19 with hypoxia who required oxygen or noninvasive ventilation/invasive ventilation. Patients were divided into two groups as per the presence or absence of comorbidity (175 and 74 patients, respectively). Their clinical and laboratory findings, course in the hospital, and outcomes were noted. Data were analyzed using SPSS software. Results: Among all the study patients, more patients from comorbidity group presented with a N:L ratio >3.5 and raised inflammatory markers (like serum ferritin) than patients in the no comorbidity group. In patients with comorbidities, 47.43% required noninvasive or invasive ventilation as against 18.92% in those without any comorbidities. Development of deranged renal function was noted in 32.57% of patients in the comorbidity group and only 9.46% in the noncomorbid group. All except one death during the study period were in the patients with comorbidities. Conclusion: COVID-19 patients with hypoxia and the presence of comorbidities in this study had more complications and a worse outcome.
