Studying the Relationship between COVID-19 and Clinical, Laboratory, and Demographic Data in Patients Referring to Shahid Rajaei Governmental Health Centers in Bandar Lengeh

Many factors are involved in the development of SARS-CoV-2 infection in individuals in each region, such as physiological conditions, underlying diseases, and observance of personal protection and hygiene; therefore, this study aimed to investigate factors affecting the incidence of COVID-19 in Bandar Lengeh, Hormozgan province, southern Iran.

Blood samples and demographic information were collected from suspected COVID-19 patients referring to Shahid Rajaei governmental health centers in Bandar Lengeh city. Hematological, biochemical, and serological tests were performed on the samples. PCR experiment was conducted to confirm SARS-CoV-2 infection. The thorax computed tomography (CT) was performed for all patients.  

According to the PCR test results, the prevalence rate of SARS-CoV-2 infection was 26.92% among 130 individuals enrolled in this study. SARS-CoV-2 infection was more prevalent among clerks than in other occupational groups (p=0.017). Increased ESR (erythrocyte sedimentation rate) and decreased WBC (white blood cell), lymphocyte, and platelet counts were evident in COVID-19 patients. Also, the prevalence of COVID-19 infection was higher in patients with blood group A (33.3%) than in patients with other blood groups. The CRP (C-reactive protein) test was positive for 31 patients whose PCR test was positive for SARS-CoV-2. In addition, LDH (lactate dehydrogenase) level was higher in infected individuals compared to other participants (p=0.018).   

In addition to the PCR test result, the most effective factors for diagnosing COVID-19 patients best on blood tests were as follows: increased CRP, ESR, and LDH levels and decreased WBC, lymphocyte, and platelet counts.
