Tetanus Main brain Tetanus main (Hanta capitālisis) is an acute infectious disease of humans caused by exposure to a specific infectious agent (pathogen).
The main epidemic characteristic of the disease is sporadicity (cases of mass or widespread spread are not recorded and there is no data on epizootic connections with other points), but often the epidemic process becomes sporadic, turning into a common pattern. The epidemic season of the disease occurs in the winter-spring period; the development of epidemics proceeds slowly. The true incidence of the infectious disease is not reliably known. Among all sources of infection, asymptomatic carriage predominates, accounting for about 60% of all infected people.
As a rare infectious disease, it occurs mainly in the northwestern counties; it is observed less frequently throughout the entire range of the disease, but always in the same limited number of epidemiological points. The main focus of infection is healthy carriers, communication with whom is observed in the presence of crowded life in children's groups, cities, and military units. The season of the disease is tied to the winter-spring rhythm of time; the disease occurs in an acute form. The prognosis is, as a rule, favorable, although the severity of the epileptiform syndrome, especially in childhood, gives reason to consider this prognostic indicator as doubtful. In exceptional cases, death may occur from complications of the disease.
