Background: The pandemic of Covid-19 is spreading around the world. Extensive research is needed to focus on identifying the underlying causes of the disease. This study aimed to investigate the clinical and etiological symptoms of the Covid-19.
Methods: This descriptive-analytical study, conducted on 510 infected patients in the infectious disease clinic of Imam Khomeini Hospital in Tehran from March 2019 to June 2020 for A period of Four months during the first wave of Covid-19 pandemic. The method of selecting patients was continuous and was divided into two groups of 179 inpatients and 331 outpatients based on lung scan and clinical symptoms. Demographic information, clinical signs, and risk factors were collected through a questionnaire and the data were statistically analyzed.

Results: Symptoms such as fever, chills and cough were reported in the majority of patients in both groups, to such an extent that they were present in 176 (52%) of outpatients and in 101 (59%) of inpatients. The mean hemoglobin measured in hospitalized patients was lower, P=0.001). Vitamin D3 supplementation was reported in 30% of outpatients and in 16.5% of hospitalized patients (P=0.001). This means that vitamin D3 consumption is higher in the outpatient group.
The results showed that Chronic diseases such as hypertension was 4.9 times more likely (OR=4.9, 95% CI2. 433-10.25, P=0.0001) and anemia with 22 times more likely (OR=22.905, 95% CI9. 355-56.083, P=0.000) to be effective in the severity of the disease. It seems Vitamin D3 intake has a supportive effect on reducing the severity of the disease and decreases the risk of the disease getting worse.
