Final answer:
Post bone marrow transplant, a patient is more susceptible to Cytomegalovirus (CMV) due to the immunosuppression required for the transplant. This is because CMV often remains dormant in the body and reactivates during periods of immunosuppression, like post-transplant.
Step-by-step explanation:
After a patient has received a bone marrow transplant, they are indeed more susceptible to various types of infections due to the immunosuppression required for transplantation. However, one virus in particular that poses a significant risk is Cytomegalovirus (CMV) or Human Herpesvirus 5 (HHV-5).
CMV has high infection rates in the human population and while it typically remains asymptomatic, it can potentially become severe in immunocompromised hosts. Notably, CMV is a major pathogen amongst transplant recipients, including bone marrow transplant patients. Specifically, approximately 60% of transplant recipients will have CMV infection and more than 20% will develop symptomatic disease. Serious consequences of CMV infection may include liver damage, transplant rejection, fever, and a decrease in the number of white blood cells in the bloodstream.
Therefore, the answer to your question is b. CMV.
