CLINICAL OBSERVATIONS ON 101 CASES OF TICKBORNE ENCEPHALITIS,
Abstract
A report is presented on the clinical observations of tickborne encephalitis occurring in a forest region in 1952-1954. The epidemic began from the first ten days of May and ended in the middle of September with the peak in June, in which 66.3 per cent of the cases occurred. This strict seasonal variation was closely related to the incidence and activities of ticks found in the forest. All the 101 patients were workers in the forest, 69.3 per cent being lumber workers. All had a history of tickbite. 79.2 per cent of them were in the age groups of 21-41 years. Most of the patients came from non-epidemic areas. The mortality rate was 21.7 per cent. Clinically the disease was characterized by a sudden onset (91.1 per cent) with high fever for five to ten days or an average of 8.8 days. The chief symptoms were neuropsychiatric disturbances: meningismus 56.4 per cent, semiconsciousness 53.5 per cent, and paralysis 83.2 per cent, with upper extremities paralysis 14.9 per cent, upper extremities plus shoulder girdle paralysis 19.8 per cent. Prognosis, criteria of diagnosis and treatment are discussed. Aureomycin was used in 7 cases with no definite effect. (Author)
