A University of Miami study found that beach goers who swam at a South Florida beach were at higher risk of sickness in the week after their visit compared to people who stayed out of the water. Out of a group of 1,300 volunteers, the half that spent just 15 minutes in the water were more than 1.5 times more likely to suffer a gastrointestinal illness, nearly 4.5 times more likely to report having a fever or respirator illness and six times more likely to report a skin illness in the week after their visit. (Will this affect the booming surfing-dogs industry?)
