The total number of heat-related patients surpassed 2,800 on Monday amid an unwavering heat wave, approaching the second-highest record in history, the state disease control agency said.The Korea Disease Control and Prevention Agency reported 41 new patients, bringing the total to 2,814 since May 20, when the agency began monitoring heat-related illnesses for this year. The monitoring will continue until Sept. 30.This tally is just four short of the 2,818 cases recorded in 2011, which stands as the country's second-highest heat-related patient record. The highest number was recorded in 2018 with 4,526 cases.So far this year, 24 patients have died due to extreme heat. Of the total, men accounted for 77.3 percent. People in their 50s and 60s made up 18.7 percent and 18.6 percent of the cases, respectively. By occupation, manual workers represented the largest portion at 22.6 percent.The Korean Society of Emergency Medicine warned that heat-related illnesses can occur even in the morning hours, as some people begin working very early to avoid the intense heat later in the day.Meanwhile, the country's maximum power demand reached 95.6 gigawatts at 6 p.m., marking the highest level in history and breaking records for the fifth time this summer, according to the Korea Power Exchange.The record high in power demand was driven by scorching hot weather, dry winds, and the influence of a typhoon bringing hot and humid air to the region.Typhoon Jongdari, located over waters some 200 kilometers west of Japan's Okinawa as of 3 p.m. Monday, is currently moving northward, heading toward the western side of the Korean Peninsula, according to the Korea Meteorological Administration.The typhoon is forecast to pass over waters southwest of Jeju Island around 9 a.m. Tuesday and continue moving northward before weakening to a tropical low-pressure system over waters southwest of Seosan, South Chungcheong Province, at approximately 9 a.m. Wednesday.High levels of power demand are expected to continue throughout this week, as Typhoon Jongdari's direction and extent of impact remain largely unpredictable.Source: Yonhap News Agency
