Abstract:
Rationale:Carbon monoxide (CO) is a colorless, odorless gas produced by carbon-containing substances, most
commonly incomplete fuel and biomass combustion. Carbon monoxide deprives the human body
of oxygen, leads to severe poisoning and death. In 2017, there were 137 new cases of carbon
monoxide poisoning per 1,000,000 people worldwide, and 4.6 deaths per 1,000,000. The global
incidence of carbon monoxide poisoning has remained steady over the previous 25 years, while
mortality has decreased by 36-40%. Every year in Mongolia, 700-840 persons are hospitalized for
carbon monoxide poisoning. Also, there has been a lack of study into the prevalence and causes of
carbon monoxide poisoning and death.
Goal:Study the dynamics of morbidity and mortality cases caused by carbon monoxide poisoning in
Mongolia.
Objectives:
To analyze the carbon monoxide poisoning morbidity recorded in Mongolia between 2016-2020.
To analyze the carbon monoxide poisoning mortality reported in Mongolia between 2016-2020.
Material and Methods:The survey was conducted utilizing data from outpatient and inpatient poisoning and deaths reported
in 2016-2020 with the goal of studying carbon monoxide poisoning and mortality in Mongolia.
Workplace exposure poisoning was excluded from quantitative data on carbon monoxide poisoning
(fires, suicidal, accidental and domestic explosions, accidents, external effects).The statistics analysis
was performed using 23 versions of the SPSS program, to estimate a distribution of new cases
and fatalities per 10,000 population depended on age, sex, average number of hospital days, and
standard error. ArcGIS version 10.8 was used to map the locations.
Results:Acute carbon monoxide poisoning. Carbon monoxide poisoning was 0.01-0.31 cases per 10,000
population during 2016 and 2018. Between 2019 and 2020, it increased to 1.5-1.9 cases per 10,000
population, with up to 37% of those admitted to hospitals. In the last five years, carbon monoxiderelated deaths have been reported in 0.1-0.3 cases per 10,000 population. The amount of hours firing
of the households increases every year in September, when the colder season begins. Incidences
of death and intentional poisoning were reported in Arkhangai, Uvurkhangai, Khuvsgulaimags, and
Ulaanbaatar. The average age of poisoning patients admitted to the hospital was 33 ± 19.5 years old
(minimum 2 months, maximum 81). In terms of gender, women registered for 58.4 (734) percent of
all cases. The average number of days spent in the hospital was 3.4± 3.7 days.
Carbon monoxide poisoning-related mortality. During the previous five years (2016-2020), 353 people
died in Mongolia as a result of carbon monoxide poisoning, although 1.4 percent, or five people, died
in hospitals, one case in Bayan-Ulgii, Zavkhan, and Uvs aimags, and two cases in Ulaanbaatar.
However, 98.6 percent of them died prematurely at home or in poisoned places due to a lack of
access to health care. The average age of carbon monoxide poisoning deaths cases was 35 ± 19.9
years old, and 71.7 (253) percent were male. The Ulaanbaatar, Selenge, Uvs, and Dornod aimags
had the lowest death rate of 0.08-0.21 per 10,000 population, while Khuvsgul and Arkhangai aimags
had the highest death rate of 0.96-1.57 per 10,000 population.
Conclusions:Carbon monoxide poisoning among the population rises during the winter season, however, in the
previous five years, 96.5 percent of cases have been poisoned accidentally, particularly 82.6 (1035)
percent of cases reported in Ulaanbaatar. According to socioeconomic factors, 41.6 (529) of the
cases were male, with an average age of 36.5±15.4 years.
During the preceding five years, carbon monoxide-related mortality in Mongolia was between 0.2 per
10,000 people. Without medical attention, 99.2% of cases died at the exposed location or area. The
death rate in Khuvsgul aimags was low, whereas it was high in Ulaanbaatar city. The average age of
premature deaths was 35±19.9 years, and 71.7 (253) percent were male.
