Abstract Reliable diagnostic methods are recommended for the identification of the exact cause of infection, so that antimicrobial therapy is directed to the specific pathogen. Frequent screening for respiratory viruses should be incorporated in the routine diagnostic study of cancer patients receiving their chemotherapy especially those with hematologic malignancies as they are more vulnerable to LRTI and had no specific radiological findings. Prompt and reliable diagnostics of infections is crucial for identification of patients and hospital staff who may be spreading viruses. Isolation and cohorting of infected patients is part of infection control policy. Restricting visits and prohibiting symptomatic subjects to visit the hospital is important, as well as prohibiting hospital staff with symptoms of respiratory disease to work with immunosuppressed patients. The only vaccine available for respiratory viruses is inactivated influenza vaccine, even if the immune response may be incomplete. The immunization of family members and hospital staff is beneficial. |
