ABSTRACT
Respiratory infections are among the most common and serious infections after solid organ transplantation (SOT). Infections within a month after transplant are usually donor-derived or bacterial infections related to surgical infections or ventilator associated. Infections between 1-6 months after SOT are mostly opportunistic due to various viruses, or fungal infections. After 6 months of transplantation usually community acquired infections predominate, however it is not uncommon to find opportunistic fungal and viral infections in this period. The signs and symptoms of these infections are often mitigated in SOT recipients, so a high index of suspicion is required along with microbiological or tissue diagnosis early in the course to timely treat these infections. Thorough screening for common infections and endemic infections is required in donor and recipients before transplantation to reduce the risk of infections in posttransplant period. Finally, a longer duration of treatment and prophylaxis is required for adequately treat these infections and prevent the relapse.
