We had a crew member come down with it last week 2 days after arriving at Sopers Hole for a sleep aboard. HE HAD 3 DAYS OF severe headaches, body aches, and fever. Tylenol got his fever down and by end of week he was better. Mosquitos were there yesterday as we were checking out, I killed a couple in our cabin loaded with blood. Waiting now to see if I react. Bring your off or take your chances.
