Description
Summary:A 26-year-old man with no substantial medical history presented to an academic emergency department in Winnipeg with a headache and associated neurologic symptoms. The patient reported that earlier in the day while driving a car, he had felt a sudden tingling and numbness in his right foot. This subsequently spread up the right side of his body to his right leg, right arm, and the right side of his face. The episode lasted about 10 minutes before the symptoms spontaneously resolved. Later the same day, a second episode of right-sided numbness occurred. This time, the symptoms were associated with difficulty speaking, prompting the patient to go to the emergency department. Jamestown Canyon virus, a California serogroup virus, is widely distributed across Canada. Transmission to humans occurs through the bite of an infected mosquito. Most patients exposed to the virus have no symptoms, but infection can result in a nonspecific febrile illness or neuroinvasive disease including meningitis and encephalitis.
