He noted that the first symptoms of PAM start one to seven days after initial infection, and said anyone who swam at Willow Springs more than eight days before it closed was not at risk. Early symptoms include headache, fever, nausea or vomiting, while later symptoms can include stiff neck, confusion, loss of balance, seizures and hallucinations. Once symptoms begin, the disease typically progresses rapidly.
