Objective To analyze the characteristics of non-occupational carbon monoxide poisoning cases in Songjiang District in order to implement targeted prevention and control work.
Methods A descriptive analysis was conducted on the non-occupational carbon monoxide poisoning cases reported in Songjiang District, Shanghai, from 2011 to 2021.
Results A total of 412 non-occupational carbon monoxide poisoning cases were reported in Songjiang District of Shanghai from 2011 to 2021, with 2 deaths and an average annual incidence rate of 2.00/100 000. The poisoning cases mainly occurred in the winter and spring seasons, accounting for 75.0%(309 cases), and the number of cases per month was negatively correlated with the monthly average maximum temperature(r=-0.755, P < 0.05). The most cases occurred in the urban-suburban transition area, accounting for 38.83%(160 cases), while 72.82% of the cases occurred at home. The majority of poisoning patients were young and middle-aged. The main causes were due to charcoal heating and improper use of gas water heaters.
Conclusions Targeted health education on the prevention of carbon monoxide poisoning should be carried out in the winter and spring seasons, emphasizing the importance of indoor ventilation, the proper use of charcoal, gas water heaters, and other related facilities. Awareness should be raised about the potential new sources of poisoning risks to effectively prevent non-occupational carbon monoxide poisoning.
