Several researches have sought to explain the link between ABO blood types and infection transmission. People with the O blood type and a positive Rh are more susceptible to blood-borne diseases, according to research. The data showed the effects of blood group types on hepatitis C were minimal to address this problem. Furthermore, persons who tested positive for Rh were 4.3 times more likely to be infected with hepatitis C. This contradicts the findings of the aforementioned study, which found that negative Rh had the greatest rate of anti-HCV. Our findings might indicate that those with negative and positive Rh have a higher risk of HCV infection than others, although this cannot be linked to a particular blood type. To get a better understanding of this trait, larger-scale experiments are necessary [10].
These findings are somewhat consistent with those reported in another research conducted in Babol, Iran. They discovered no significant relationship between chronic hepatitis B and its treatment and ABO blood groups in that research, but they did identify a strong link between Rh type and chronic hepatitis B, with 97.9% of chronic carriers having positive Rh. Although there was no significant link between becoming infected and blood group types in the current investigation, People with the O+, A+, and B + blood types, on the other hand, had a greater prevalence of HCV and HBV than others [11].
Furthermore, it was found no significant link between positive HBsAg status and blood group types in another investigation. In line with the previously published results, an Iraqi investigation found that HBsAg and HCVAb were more common in persons with the O + and rare in those with the AB blood group. Furthermore, those with hepatitis infection had a higher rate of positive Rh factor than those who did not [12].
Furthermore, it was found that those with the O + and positive Rh blood types had the greatest rates of hepatitis [13].
Another research in Nepal revealed no significant link between HBV and blood types, however persons with the positive O + had a greater risk of developing these illnesses [14].
There was no consistent link discovered between the data and our findings. They demonstrated that blood types other than O + are a hereditary risk factor for liver fibrosis progression. This might be owing to an increased risk of venous thrombosis in HCV-infected individuals [15].
According to a Chinese research, persons with the AB and B blood types were more likely to be infected with the hepatitis B virus than those with other blood groups [16].
However, a research done in Iran found that persons with the B + had a larger proportion of CD4 + T-lymphocytes than those with other blood groups. As a consequence, it may be assumed that persons with the B blood type have a reduced risk of viral and infectious illness [17].
