As of August 5, the number of heat-related deaths this summer has surpassed last year's figures, with fatalities reported for four consecutive days since August 1.
According to Yonhap News and the Korea Disease Control and Prevention Agency, 198 individuals sought treatment for heat-related illnesses at over 500 emergency rooms nationwide on August 4. Among them, a man in his 60s from Eumseong, North Chungcheong Province, died while working in the fields.
Additionally, a death reported on August 3 was confirmed later; it involved a man in his 70s from Gyeongju, who was found in his backyard.
Since the heat-related illness surveillance system began on May 15, the total number of cases has reached 2,441, with 21 deaths. Notably, this year has seen continuous fatalities since August 1, indicating ongoing heatwave impacts.
A significant point of concern is the rising mortality rate despite a lower number of cases. The cumulative cases this year are about 75% of last year's total of 3,238 during the same period, yet the death toll has exceeded last year's 20. The case fatality rate has increased from 0.62% last year to 0.86% this year, highlighting the growing risks associated with heat-related illnesses.
The heatwave has intensified this month, with daily reports of over 100 heat-related cases since August 1. On August 3, there were 202 cases, followed by 198 on August 4, indicating a consistent trend of around 200 patients seeking emergency care.
Demographically, men account for 77.1% of the cases, while individuals aged 65 and older represent 33.8%. The data suggests that older adults, particularly those engaged in agricultural work or outdoor activities, are disproportionately affected.
Among the types of heat-related illnesses, heat exhaustion accounted for 61.7%, followed by heat stroke at 16.8%, heat cramps at 11.5%, and heat syncope at 8.6%. Heat stroke is considered the most dangerous heat-related condition, as it can lead to a core body temperature exceeding 104 degrees Fahrenheit, resulting in altered consciousness, delirium, or seizures, and can be fatal without prompt medical intervention.
The Korea Disease Control and Prevention Agency urges the public to stay hydrated, wear light-colored and loose-fitting clothing, and take measures to lower body temperature during the ongoing heatwave. They also recommend avoiding outdoor activities during peak sunlight hours and reducing the intake of alcohol and caffeinated beverages, which can increase the risk of dehydration.
If someone exhibits symptoms of heat-related illness, they should be moved to a cool location to lower their body temperature, and if severe symptoms such as altered consciousness occur, emergency services should be contacted immediately.
