Symptoms of encephalitis start with a fever, accompanied by a severe headache and a stiff neck. Anyone experiencing these symptoms at this time should consult with a physician. Health officials in Indiana are advising people to use repellents when in areas that mosquitoes are biting. Use of repellents should be done with caution, and users should always follow the directions on the label. The New York State Department of Health does not recommend that repellents with concentrations of more than 15 percent active ingredients be used on children.
Pediatric formulations are available.
