Featured Disease of the Week
Carbon Monoxide Poisoning
Silence isn't always golden, especially when it comes to carbon monoxide (CO) poisoning. CO is an odorless, colorless gas that can cause sudden illness and death. When power outages occur after severe weather (such as hurricanes or tornadoes), using alternative sources of power can cause CO to build-up in a home and poison the people and animals inside.
