Abstract


In every winter carbon monoxide poisoning (CO-poisoning) has been one of the most serious public health problems in Korea. Undoubtedly its prevalence should be the highest in the world, mainly due to the unique heating and cooking system with smokeless coal (anthracite) in most Korean houses.
The author has made a survey on the epidemiology of the CO-poisoning in the special city of Seoul, during the period of January 1, 1968 to March 31, 1969. The data were collected from the City Police Headquarters and seventeen general hospitals having the capacity of 50 or more operating beds. Meteorological data were obtained from the Central Weather Bureau.
The followings are the summary of this study.
1. In 1968, there occurred 1,563 serious CO-poisoning patients, and 363 among them being fatal.
The incidence was slightly higher in female than in male. The fatality, however, was higher in male than in female. There was 93 percent increase in the number of the patients during a period of
January to March in 1969, in comparison with that of 1968.
2. Among the age groups, the incidences were higher in the old (above 60) and the young (25-29) ages, while the fatalities were higher in the children (0-9) and the old (above 60).
3. The incidence by month revealed the highest in November and the lowest in August. 4. The incidence by area revealed the central are of the city to be higher than the peripheral areas.
The overall incidence rate of the city showed 36.1 per 100,000 population and the fatality was 23.2 per cent. The predicted incidence in 1969 was 69 per 100,000 population.
5. The wide variations of fatality was encountered in each hospitals. However, the average was 9 per cent. The overall fatality including the figures during and post-hospitalization will reach 23 per cent.
Of the daily incidence data, the highest one was 36 patients in a day. The highest
average daily number of patient was observed in November(11.3) and the lowest in August(0.9).
7. In relation to the meteorology, there showed a tendency to be higher in incidence in the weather condition of relatively higher temperature and humidity, and with the low er atmospheric pressure e and wind velocity. S. CO Alarm Index (.33.3 x (Pa-Pap/0.58 + R.H.p.-R.H.a./2.5 + Va-Vp/0.32) was induced with the functions of atmospheric pressure, relative humidity and wind velocity, and this value was evaluated for its applicability. And it was proved to be significant for the alarming of CO hazard.
