The coinfection of pathogenic bacteria and COVID-19 represented a true health challenge. The current study aimed to estimate the incidence of <em>H. pylori</em> in patients with COVID-19. <span dir="RTL"></span><br> <strong>Materials & Methods:</strong> This experimental study was conducted in Karbalaa&#39;s COVID-19 Isolation Center from Feb. 2021 to July 2021, 130 COVID-19 patients were entered the study. A control group of 130 seemingly healthy people of similar ages and sexes was also enlisted in this research. COVID-19-infected patients were confirmed by Reverse Transcription-Polymerase Chain Reaction device. The samples were processed for total WBCs, and neutrophils were automatically computed. Data were analyzed using SPSS 21 software by independent T and Chi-square tests.<br> <strong>Findings:</strong> COVID-19 infection was more frequent in males than females, especially between 15 and 25 years. The COVID-19 patients were detected to have increased neutrophils count (p<0.0001) and decreased lymphocytes compared to the healthy persons (p<0.0001). A significant correlation between <em>H. pylori </em>and COVID-19 was discovered, especially in females.<br> <strong>Conclusion: </strong><em>H. pylori</em>-infected patients are more susceptible to COVID-19 than other persons without <em>H. pylori</em> infections.</div> COVID-19,Helicobacter pylori,Correlation Study,Co-infection, 255 259 http://ijwph.ir/browse.php?a_code=A-10-1818-1&slc_lang=en&sid=1 Y.
