H. Influenzais a bacteria that causes many infections inside the human body, such as pneumonia. In this study, a total of (60)blood samples were taken from patients infected with SARS COV-2shared with H. Influenza infection who attended Ibn-Al-Baladi Hospital/Baghdad city during the period from 15^th January to 1^st December 2021. Venous blood samples were also taken from (60) healthy individuals as a control group. The results showed that the distribution rate of the SARS COV-2 IgG and H. influenza IgG among the male patients was twice44 (73.3%)more than the distribution rate among female patients. The prevalence of SARS COV-2 IgG and H. influenza IgG was shown to be the highest among the age group (>51) years, followed by the age group (21-30) years. The cases of SARS COV-2and H. influenza infections among the studied patients according to residency were shown to be almost equal among rural and urban residents 30,30 (49.2%,50.8%) respectively. Regarding the relationship between SARS COV-2 IgG and H. influenza IgG and CRP levels, the mean level of CRP in the patients was (73.72±17.05) and in the the controls was (8.71±1.12), while the mean level of H. influenza IgG in the patients was (1.05±0.23) and in the control group was (0.3±0.02), whereas the mean level of SARS COV-2 IgG was (7.00±2.15) in the patients andwas (0.35 ±0.19) in the controls with a highly significant differences (HS).The number and percentage of patients with positive SARS COV-2 and H. influenza IgG was 38(95.0%) who had high levels of GOT up to 65 U/L, while 2(50%) of those patients had GOT >65 U/L, while the Negative infections with SARS COV-2 IgG, H. influenza IgG 17(85.0%) had up 65 U/L and 3(15.0 %) had>65 U/L level (P =0.03).In addition, high levels of GPT, Alkaline phosphates, urea and creatinine were recorded among patients groups when compared with the healthy controls. https://biomedpharmajournal.org/vol15no1/mutation-occurrence-in-tor2-gene-in-patients-with-sars-cov-2-in-aassociation-with-h-influenza-infection/ H.
