Investigating the Coronavirus Disease 2019 Process and its Related Occurrences during the Treatment Course.

Background: The disease process involves the occurrences happening during the disease and treatment course for the patient. Investigating this process is a significant and necessary issue for all diseases, including coronavirus disease 2019 (COVID-19).

Materials and methods: Using the information of 4372 patients with COVID-19 referring to Dr. Masih Daneshvari Hospital in Tehran during the COVID-19 epidemic, being hospitalized, cared for, and home quarantined due to having mild symptoms, the COVID-19 process and its related occurrences were investigated during the treatment course.

Results: In the COVID-19 course, considering the disease severity, the likelihood of hospitalization in the general ward or the intensive care unit (ICU) ward, the likelihood of isolation or home quarantine, and the likelihood of occurrences such as recovery or death at the end of the disease course were taken into consideration. Based on the results of this study, the likelihood of hospitalization in the general ward, the ICU ward, and isolation or home quarantine was determined to be approximately 49.54%, 14.73%, and 35.73%, respectively. Also, for patients hospitalized in the general ward, the ICU ward, and isolated or home quarantined, the likelihood of recovery was estimated at approximately 64.79%, 10.82%, and 96.31%, respectively, and the likelihood of death was also estimated at about 35.21%, 89.18%, and 3.69% respectively.

Conclusion: Investigating the COVID-19 process and estimating the likelihood of incidence of its related occurrences during the treatment course both create an accurate prognosis and provide the possibility of achieving an efficient treatment for these patients.
