The rate of hospitalizations for CO poisoning varied from year to year between 2000 and 2015. Between 2007 and 2009, Minnesota began implementing a law requiring CO alarms in all single-family homes and multi-dwelling buildings. The new law could be a factor in the decline in CO poisoningsthe age-adjusted hospitalization rates after 2009.
