Discussion
COVID-19 infection was seen typically in middle-aged, man gender and elderly patients, and patients with other diseases were more susceptible to disease. A greater number of men was found than that of women, which was similar to previous studies (Wang et al., 2020, Jiang et al., 2020). women have a humoral immune response and greater innate than men and are thus less susceptible to many parasitic, fungal, bacterial, and viral diseases, while being more prone to developing a malignancies or autoimmune disease (Schurz et al., 2019). While these sex differences in rates of mortality may be due to sex- specific life styles (smoking, alcohol etc.)(Wrapp, Zarghami et al., 2019). Cough, fever, and dyspnea were main symptoms. abnormal lymphocyte, neutrophil, , SGOT, and SGPT, increased CRP concentration and increased LDH concentration were the laboratory features of COVID-19 infection in present study. abnormal HRCT was seen in 88% of the patients as main indicator to evaluate the COVID-19 disease severity as other researchers(He et al., 2020, Zhang et al., 2020b).furthermore, WBC count, O2 saturation, and were associated to lung involvement significantly, statically.
