The rate of hospitalizations for CO poisoning varied from year to year between 2000 and 2013. Between 2007 and 2009, Minnesota began implementing a law requiring CO alarms in all single-family homes and multi-dwelling buildings. Starting in 2009, there was a decline in the age-adjusted hospitalization rate of CO poisonings, which could be attributed to the new law.


Older males have the highest risk
