An Epidemiological Study of Carbon Monoxide Poisoning Rate and a Comparison with Other Poisonings Recorded in Mazandaran Department of Forensic Medicine, 2009-2011

Carbon monoxide is an odorless, colorless and poisonous gas. Since there is currently no information on the prevalence of carbon monoxide poisoning in Mazandaran, this study aimed to investigate the prevalence of carbon monoxide poisoning and compare its prevalence with other poisonings recorded in Mazandaran Department of Forensic Medicine, from 2009 to 2011. This is a descriptive-analytical study, in which the information was received from Mazandaran Department of Forensic Medicine. Among the 2446 human deaths in 2009, 2010, 2011, 237 deaths were due to poisoning and 27 (11.4%) were due to carbon monoxide poisoning, which ranked third after narcotic and Aluminum phosphide intoxication. Poisoning in males was 1.7 times more than females. Co was the most common cause of deaths among people aged 21 to 30 years. Considering the fact that in most cases of poisoning deaths caused by CO (silent killer) come by quietly and in a hidden manner, CO actually makes any defense and escape impossible for the person and despite seeing the shadow of death, that person will inevitably surrender and will be defeated. Therefore, it is necessary to educate and inform the public through media and educational institutions about the risks and sources of CO poisoning.
