Viral infection not responsible for exacerbation of lung disease in most patients

Researchers found no evidence of viral infection causing acute exacerbation of idiopathic pulmonary fibrosis (IPF) in most patients. Instead, torque teno virus (TTV) was detected in lung fluid samples from a small percentage of IPF patients, suggesting it may be a marker of lung injury rather than a cause.
