Why It Matters
Legionnaires' disease, caused by Legionella bacteria, can lead to severe pneumonia and requires prompt antibiotic treatment in hospital settings. The steady increase in cases highlights the importance of maintaining water systems in buildings and public facilities to prevent bacterial growth, particularly for vulnerable populations including older adults, smokers, and individuals with weakened immune systems.
