Classification of infectious diseases
Epidemiology / / August 12, 2017
need for classification (division) of infectious diseases at the naturally formed groups felt for a long time.This is understandable, since it is difficult to operate a huge factual material relating to similar, but not identical to infectious diseases, if they are not given in any system.
long time, infectious diseases were divided into contagious (transmitted by contact from person to person), miasmatic (not transmitted by contact from person to person) and a contagious-miasmatic (intermediate group).
At the end of the 18th century under the influence of microbial discoveries were brilliant classification, which was based on the etiological feature.With this approach, unwittingly equates germs and infectious disease.Therefore, one group found themselves the disease, differ in pathogenesis, clinical course and epidemiological laws.
Later, there have been numerous attempts to classify infectious diseases on clinical and epidemiological grounds.The classification proposed by clinicians combine infecti
first consistently sustained classification of infectious diseases, based on a single criterion (localization of the pathogen in the body), proposed by LV Gromashevskiy.In accordance with the main localization of the pathogen in the body that determines the transmission mechanism, all infectious diseases divided them into 4 groups:
1) intestinal infections;
2) respiratory tract infections;
3) blood infection;
4) infection integument.
