Early Treatment

Why Early Treatment Matters

Untreated or mismanaged respiratory infections can lead to:

  • Respiratory failure and hospitalization
  • Spread of infection into the bloodstream
  • Lung abscesses or chronic scarring
  • Long-term breathing problems
  • Transmission of contagious infections (like TB or influenza)
