Floods in Thailand have killed 23 people and sickened 230,000 in the past two weeks, including many who contracted ailments after wading through dirty water, the government says. The 23 people were swept away by flash floods that have afflicted 27 of Thailand's 75 provinces since early September, the Ministry of Public Health said in a statement Tuesday. Most of those who sought medical treatment had skin funguses, cold symptoms and respiratory problems. The Health Ministry warned residents that floodwaters were full of parasitic leeches, human waste and bacteria that can cause skin infections and fungus.
