Swimming, fishing or playing in unsafe waters may result in minor illnesses such as sore throats or diarrhea. It may also result in more serious illnesses such as meningitis, encephalitis, or severe gastroenteritis. 

Children, the elderly and people with weakened immune systems have a greater chance of getting sick when they come in contact with contaminated water.
