Cumulative Imaging Damage with Reinfection
1 infection+22.4% fibrotic changes
2+ infections+31.2% fibrotic changes
Reinfection+OR 1.8 for persistent CT abnormalities
“Each infection compounds structural lung damage visible on imaging”
THE HOPEFUL HORIZON
- CT abnormalities continue to improve up to 12 months post-infection[14]
- Cardiac MRI edema typically resolves by 6-8 weeks[5]
- 65% with initial cardiac dysfunction show functional recovery[40]
- AI-based imaging tools improving early detection and prognosis[41]
