Maui has a mouse infestation. And, health officials say the time of year and the amount of mice are unusual. The main problem is along Honoapiilani Highway. Maui District Health Officer Doctor Lorrin Pang says the mice may contain fleas, which carry a bacterial disease called Typhus. It can be deadly to humans. Those afflicted develop a rash and other symptoms such as headaches, fever, and muscle aches.
