Role of Co-Infection in the Immunopathology of COVID-19 in pregnancy

“Co-infection” differs from single infection mainly in the effect of co-infection on the host health which may be harmful, beneficial or absent. This effect occurs mainly due to changes in host immune response. Co-infection is used in treatment of other diseases not just infectious ones. It’s well known that co-infection may have beneficial effects that can improve overall outcome better than single agent infection especially in case of viruses. There are many immunological mechanisms to achieve that. As co-infection has a beneficial effect that we may use it in treatment, there is harmful effect that we should avoid. In this review we tried to evaluate the effect of co-infection in pregnancy with coronavirus disease-2019 (COVID-19) and how the immune system of the pregnant women will respond to co-infection.
