Abstract
|
|
|
In 2013, the Korea Disease Control and Prevention Agency (KDCA) launched a cold-related illness (CRI) surveillance system. Every winter (December-February), a nationwide network of approximately 500 hospital emergency rooms (ERs)
participates in the system. The KDCA operates the CRI surveillance system to monitor hypothermia, frostbite, trench foot or
immersion foot, and chilblain. According to the hospital reports, 433 people developed CRIs and 7 deaths were attributed to
CRI in the 2020-2021 winter season. The average lowest temperature in the 2020-2021 season was ?3.9℃, lower than that
of the 2019-2020 season (-1.4℃) which can be attributed to the long-term cold that occurred for about 15 days at the end of
2020 and the start of 2021. The number of CRIs was highest in January (54.5%), and deaths attributed to CRI were highest in February (42.9%). Findings indicated that the percentage of CRI occurrences was high among males (70.2%); high among people in their 80s (21.0%); high among the unemployed (33.9%); and high among drinkers (23.6%). Findings indicated that CRIs occurred mainly between 6 am and 12 pm (30.9%); and the main cause of CRI was hypothermia (67.4%). In terms of location, CRI occurrence was highest at outdoor roadside locations (26.8%) followed by outside the home (nearby residence) (17.8%) and inside the home (13.6%).
