Air quality alert downgraded in Baltimore, but health risks from smoke remain

Smoke from Canadian wildfires caused a Code Red air quality alert in Maryland, leading to residents wearing masks outdoors. While the air quality has improved, a downgraded Code Orange alert still advises sensitive groups, such as children, those with asthma or heart/lung diseases, and the elderly, to take precautions and avoid strenuous outdoor activity. Johns Hopkins will hold a briefing to address health concerns and discuss future preparedness.
