The study included 315 patients diagnosed with COVID-19 and 1402 diagnosed with seasonal influenza. The results showed that patients with COVID-19 and those with seasonal influenza had a similar hospitalization rate, intensive care unit admission rate, and use of mechanical ventilators.
More patients who were hospitalized with COVID-19 than with seasonal influenza reported fever, diarrhea, or vomiting, headache, body ache or myalgia, and chest pain. Further, differences between patients hospitalized with COVID-19 versus influenza who reported cough and shortness of breath were not statistically significant.
The researchers concluded that there was no difference in hospitalization rates, intensive care unit admission rates, and mechanical ventilator use between the 2 groups. In addition, more patients hospitalized with COVID-19 reported clinical symptoms at the time of diagnosis than with seasonal influenza, according to the study.
