According to health officials, the heavy rain earlier this week caused some storm water runoff.
The department received two reports of people who may have gotten leptospirosis. It is a disease that can cause flu like symptoms and lead to death if left untreated.
There has been a brown water advisory issued for Waimea Bay. So remember if the water is brown, stay out.
"It's typically a lot of people getting into fresh water especially under storm condition that we ask people to be especially careful and be wise not to go in the water especially if you have open cuts," said Department of Health Director Gary Gill.
Gil says the state averages 20 to 40 cases of leptospirosis every year.
