Abstract:
Swine flu influenza had spread the world over in 2009. The main pathology was bilateral pneumonia. Majority of these cases recovered from pneumonia fully. Though in some cases, pulmonary fibrosis was reported as a sequel. However, long-term progression of such pulmonary fibrosis is uncertain. We are hereby reporting two cases of swine flu that showed residual pulmonary fibrosis. The clinical and laboratory parameters were also recorded. In both the cases, radiological shadows and spirometric values did not show deterioration. We conclude that swine flu pulmonary fibrosis is not a progressive condition.
