This paper aims to show the relationship between COVID-19 symptoms and patients' status including recovered and deceased cases. The study uses different CoVID-19 patients' information from different countries, the dataset contains 13174 patients with 730 as recovered and 34 cases as deceased. The Chi-square test is adopted with asymptotic significance level to show the strength of each symptom on recovered and deceased cases independently. The study found that the recovered cases are associated with different symptoms based on the patient history, where the deceased cases showed that high fever is not responsible for increasing the number of deceased cases. In addition, the use of symptoms will not give evidence of the patients' status, and therefore gender, age, reason of infection and patients' province are more dominant in determining the status of patients.
