A student at an elementary school in Siheung, Gyeonggi Province, was confirmed to be infected with norovirus on Wednesday after health authorities had launched a probe last week as some 50 students showed signs of food poisoning. Norovirus is a common cause of food poisoning, especially in the winter months. The highly contagious virus usually spreads through contaminated food and water. It causes vomiting, stomachache and diarrhea within 24 to 48 hours of infection. © tesecreates, 출처 Unsplash Since Friday, 52 students have been absent or left school early due to stomach pain and diarrhea.
