The SARS-CoV-2 pandemic has brought the threat of viral infections to the fore . Even seemingly healthy, young individuals can die if they contract the virus, and immunocompromised individuals may be at greater risk of a fatal outcome should they become infected . But many other viruses pose potential threats to the well-being of solid organ transplant recipients . Chief among viral threats to lung transplant recipients are cytomegalovirus and community-acquired respiratory viruses . Fortunately, we have developed strategies to prevent or blunt the impact of CMV on lung transplant recipients, but a high degree of vigilance must be maintained to screen and prevent the passage of transmissible viruses from donor to recipient.
