Viral Pneumonia and Acute Respiratory Distress Syndrome.

Respiratory viruses are a common cause of severe pneumonia and acute respiratory distress syndrome (ARDS) in adults. The advent of new diagnostic technologies, particularly multiplex reverse transcription polymerase chain reaction, have increased the recognition of viral respiratory infections in critically ill adults. Supportive care for adults with ARDS caused by respiratory viruses is similar to the care of patients with ARDS from other causes. Although antiviral therapy is available for some respiratory viral infections, further research is needed to determine which groups of patients would benefit.
