Abstract:

Chimkent oblast of southern Kazakhstan region, particularly its southern regions, are the natural foci of tick-borne hemorrhagic fever. Between 1948 and 1963 inclusive, 67 cases of the illness were registered, of which 38 56,7 were fatal. Seasonal dynamics of morbidity coincides with the curve of change of number of ticks of the genus Hyalomma, which are vectors as in Uzbekistan and possibly reservoirs of the virus in nature. One of the peculiarities of the illness is the possibility of infection by contact with bloody secretions of the patients. A short period, soon after the onset of illness i.e. 2-3 days, is a contagious period. This may be associated with changes in virulence of the agent during the illness. The incubation period in contact infection does not exceed 3 to 5 days. Mortality in such cases is equal to 60-70 however, masked or mild forms are also encountered. Observations conducted during several years disclosed the possibility of a double or triple person-to-person infection, through contact with blood containing patients secretions. Author
