A prospective descriptive study was conducted from August 2021 to September 2021 to describe the clinical and subclinical characteristics of COVID-19 patients at the field hospital of Dong Thap Community College. The study collected epidemiological data of 240 subjects. The results indicated that the male/female ratio was 1.2/1; the mean age was 29.2±15.1 (1- 65 years old). The most typical clinical symptoms of the disease are cough (45.8%), fever (45%), stuffy nose (21.7%), anosmia (13.8%), ageusia (12.9%), and shortness of breath (4.6%). Most patients have mild symptoms and a high recovery rate. This study contributes to a general assessment of clinical, subclinical factors, treatment results of COVID-19 patients in general and COVID-19 subjects at the field hospital of Dong Thap Community College in particular, which is the basis for better disease prevention measures.
