Post transplant infection is a potentially life-threatening condition that requires supportive care and preventive treatment. Due to immunosuppression and neutropenia, transplant patients are susceptible to a variety of bacterial, fungal, and viral infections. Prophylactic antibiotic therapy, antifungal agents, and vaccinations are used to reduce risk of infection. Cytomegalovirus (CMV) negative donors are preferred for patients that require blood components. Leukocyte-reduced blood products also will lower the risk of transmission of CMV to an immunosuppressed patient. Other important preventive measures include skin care and oral hygiene
