South Korea recorded 26 cases of heat-related illness over two days in May 2024, including one fatality [1].
This surge in medical emergencies is significant because the timing of the heat wave is unusually early. The death of an 80-year-old man in Seoul's Dongdaemun district occurred more than a month earlier than typical fatalities recorded in previous years [3].
The illnesses were reported on May 15 and May 16, 2024 [2]. On the first day, seven people were affected, one of whom died [1]. The number of cases rose to 19 on the second day [1].
Health officials tracked the highest concentrations of cases in Gyeonggi Province [6] and Gangwon Province [6], followed by Seoul with five cases [5]. Additionally, two cases each were reported in Chungbuk, Chungnam, and Gyeongbuk [8].
"The 80-something man who died in Dongdaemun-gu, Seoul, is the earliest death case since the emergency room monitoring system was activated," said Lee Hyun-jung of YTN News [3].
The spike in illnesses is attributed to an early heat wave that pushed temperatures to levels typically seen in early summer [4]. This rapid shift in weather patterns has left the population vulnerable before the standard summer heat precautions are typically implemented.
“26 cases of heat-related illness over two days”
The occurrence of heat-related fatalities and illnesses in mid-May suggests a shift in seasonal weather patterns in South Korea. Because these events are happening significantly earlier than in previous years, public health systems may need to activate emergency monitoring and heat-warning protocols sooner to protect elderly and vulnerable populations.
