The present study investigated the differences between elderly patients hospitalized with COVID-19 or influenza A H1N1 virus infections.

 

It contrasted two absolute groups of patients (age ≥60 years) infected with either COVID-19 (n = 222) or influenza A H1N1 virus infections (n = 96). The study compared the two groups′ clinical features, imaging presentations, therapies, and prognosis data.

 

The study observed-

 

  • Higher proportions of cough, expectoration, fatigue, and shortness of breath in patients with influenza.
  • Higher counts of lymphocytes, hemoglobin, and creatine kinase and lower counts of white blood cells, neutrophils, blood urea nitrogen, and C-reactive protein in patients with COVID-19. 
  • Bilateral pneumonia as the most abnormal pattern in the two groups of patients concerning imaging characteristics.
  • Lower incidence of acute respiratory distress syndrome or death among patients with COVID-19.

 

This study shows that the clinical manifestations of patients with COVID-19 are more suppressed than those of patients with influenza. Fewer symptoms of sputum production, fatigue, shortness of breath, and lower white blood cells, neutrophils, and C-reactive protein counts are the possible predictive factors of COVID-19 among elderly patients.
