Fungal pulmonary infections are becoming more prevalent as a consequence of the rising prevalence of immunocompromised patients. Besides ubiquitous opportunistic fungi such as Aspergillus spp and geographically delimited mycoses, fungi that were previously thought to be of uncertain pathogenicity, such as hyaline and dematiaceous molds, are increasingly being diagnosed as the causes of invasive disease in profoundly immunosuppressed hosts. ⋯ This article provides an overview of endemic mycoses and other emerging fungal pulmonary infections. Recent developments in terms of the diagnosis and clinical management of these infections are also discussed.

ReviewEmerging, novel, and known influenza virus infections in humans.
Influenza viruses continue to cause yearly epidemics and occasional pandemics in humans. In recent years, the threat of a possible influenza pandemic arising from the avian influenza A(H5N1) virus has prompted the development of comprehensive pandemic preparedness programs in many countries. ⋯ Nevertheless, the plethora of epidemiologic, diagnostic, mathematical and phylogenetic modeling, and investigative methodologies developed since the severe acute respiratory syndrome outbreak of 2003 and the subsequent sporadic human cases of avian influenza have been applied effectively and rapidly to the emergence of this novel pandemic virus. This article summarizes some of the findings from such investigations, including recommendations for the management of patients infected with this newly emerged pathogen.

ReviewEmerging bacterial, fungal, and viral respiratory infections in transplantation.
Kidney, liver, heart, pancreas, lung, and small intestine transplantations are viable therapeutic options for patients with end-stage organ failure. Ongoing advancements of surgical techniques, immunosuppressive regimens, and perioperative management have resulted in improved survival of allograft recipients. Despite these refinements, infections still contribute to substantial morbidity and mortality, limiting long-term success rates of these procedures. This article discusses the emerging bacterial, fungal, and viral respiratory infections in transplantation.

Occupational pulmonary infectious diseases include tuberculosis (TB) and many viral pathogens, including influenza, coronavirus (severe acute respiratory syndrome or SARS), varicella, respiratory syncytial virus, and hantavirus. This review focuses on TB, influenza, and SARS, because the published literature is extensive for these 3 infections. The lessons from these 3 are relevant for all nosocomial pulmonary infectious diseases.
