CLINICAL CHARACTERISTICS OF THE TICK TYPHUS OF NORTHERN ASIA
Abstract
The infections of Northern-asiatic tick typhus observed in the Far East distinguished themselves by their seasonality; it appeared in the beginning of May and terminated in October; the maximum number of infections came in the three summer months. The infections were connected with travel to rural wooded or brushy land; of 62 patients 42 bore tick bites. The incubation period was 3-5 days in a majority of the cases, but was shorter, 1 day, or longer, 10 days. The length of the incubation period did not effect the severity of the illness. The clinical course differed by a high-qualitative, and characterized itself with, a sudden commencement, fever with a duration of 9-10 days a greater part of the time, hyperemia of the face, characteristic, chiefly roseolus-papuloid rash which was more pronounced on the buttocks and thighs. The greatest titer of agglutination was obtained during serological reactions with proteus X2: with proteus X19 the titer, as a rule, was significantly lower.
