Doctor says everyone should take precautions with air quality

Air quality remains in a "code red" as of Thursday night, and a Baltimore doctor says everyone, not just those with pre-existing conditions, should take precautions. "It contains a lot of very small-sized particles that we can easily inhale, and it can go down our respiratory tract," said Dr. Revathi Jyothindran of Northwest Hospital. The smoke is drifting south from Canada due to several wildfires.
