Patients with COVID-19 have shown a wide variety of symptoms and mortality rates in different communities.

This study aimed to compare the epidemiological, clinical, and paraclinical features of patients with COVID-19 who have overcome the disease with patients who died.

All hospitalized patients admitted to Special Corona Hospital who had a positive real-time PCR test for SARS-CoV-2 from January to March 2020 were included in the study. Clinical characteristics, date of disease onset, hospital admission date, and the severity of COVID-19 were obtained from each patient’smedical records. Independent sample t-test was used to compare continuous variables between the groups of the discharged and expired patients. The independence between categorical variables and the outcome was assessed by Chi-square or Fisher’s exact tests.

The order of essential variables for admission as the starting time are pH, WBC count, loss of consciousness, neutrophil count, base excess (BE), HCO3, age, BUN, O2 saturation, and lymphocyte count.

In the current study, the mortality rate of COVID-19 was 30% and was significantly associated with critical disease intensity, fever, chills, loss of consciousness, ischemic heart disease (IHD) history, Parkinson’s disease, invasive O2 therapy, and troponin level.

During the last half century, all indices of mortality imply the prompt and continuous decrease of nationwide mortality. Alongside reduction of mortality, there happened a comprehensive form of transition of mortality causes, from epidemical and other communicable diseases such as mother's (birth giving) mortalities and birth related ones, to other causes like chronic diseases related to lifestyle and aging.
in this study, stages of epidemiological transition in Iran with emphasis on the third transition, is surveyed and finally deals with prediction of this trend in future decades.
the results show that Iran has been through the third stage of epidemiological transition for two recent decades since a large proportion of deaths are related to chronic disease such as cardiovascular disease and life expectancy at birth has decreased to 70 years. There also observed signs of the fourth transition in Iran in recent years, because as deaths caused by chronic diseases have increased, the mean age of death has also increased remarkably.
epidemiological transition dynamic and changes of death causes, must be considered according to other demographic components. Reduction of death rate, fertility related changes, and as a result changes of age structure are some causes that influence on epidemiological transition in Iran and will be influencing for some years later.
