ANS: A
Epidemic encephalitis is usually spread by mosquitoes and ticks. Use of insect repellent is effec-tive in reducing risk. Encephalitis frequently requires that the patient be hospitalized in an inten-sive care unit during the initial stages. Antibiotic prophylaxis is not used to prevent encephalitis because most encephalitis is viral. West Nile virus is most common in adults over age 50 during the summer and early fall.
