Respiratory illnesses affect the lungs and airways. Public dashboards and wastewater can show when activity is rising in a community.

How it spreads
Many respiratory pathogens spread through respiratory droplets and aerosols, especially in crowded indoor spaces.
Prevention (general)
Follow local public health guidance, stay home when ill, improve ventilation where possible, and consult a clinician for personal medical decisions.
Why people track it
Legionnaires disease often appears in official dashboards when activity rises, investigations open, or travel rules change. OutbreakThreat does not estimate personal risk; we surface what agencies have already published so you can read the original notice in context.
