Peculiarities of clinical manifestations of the new COVID-19 coronavirus infection in patients hospitalized during the epidemic depending on their age
This article presents a review of the literature and data from a personal study concerning the clinical manifestations of new coronavirus infection in patients hospitalized during the COVID-19 epidemic depending on their age. It was found that most patients complained about dry or low-productive cough, moderate general weakness. The patients aged 18–30 years old more frequently experienced no cough. The patients aged 31–40 years old significantly more frequently complained about dry cough (p < 0.05). Low-productive cough was less frequent but typical in all age groups and more frequent in patients aged 51–60 years. Moist cough was more frequent in patients over 60 years. Chest pain was registered in patients over 60 years (p < 0.05). The frequency of dyspnea was found to increase with age. More often dyspnea was registered in patients older than 60 years old. No dyspnea was noted in young patients aged 18–30 years. Half of the patients aged 18–30 years had no fever. At hospitalization, the average temperature was within normal or subfebrile, which predominated in patients aged 41–50 years (p < 0.05). The frequency of febrile fever increased in patients with age. There was no significant difference in the frequency of pyretic temperature among all age groups. The patients aged over 30 years complained more about moderate weakness, and patients aged over 40 years complained more about severe weakness. Younger patients more often complained about a sore throat, while older patients had practically no symptoms (p > 0.05). Thoracic pain was significantly more frequently registered in patients older than 60 years old. Young patients aged 18–30 years and 31–40 years had no chest pain.
