Leptospirosis is a very serious disease and if it continues to occur, it can result in numerous complications such as kidney damage and inflammation of the pancreas, liver, lungs and brain. Health problems caused by floods occur primarily due to the host, the environment and agents.The first regards the massive evacuations of residents, with the risk of inadequate cleanliness and insufficient food and water for the evacuees, which will affect their immune responses.he third is bacterial factors, the disease agents commonly found during flood disasters, including flies, rats, bacteria and dirt, causing the pollution of clean water.
