In humans, symptoms can include headache, drowsiness, and mental confusion. EEE has a high mortality rate, with some sources stating it can be 30 to 50 percent in humans. Treatment focuses on comfort, and the disease can cause permanent brain damage. Control measures involve eradicating mosquitoes and using vaccines against certain strains.12
