Text A. The Origin of Infections

The infectious diseases of man are usually divided into two large groups. Some diseases affect only men, others affect both man and animals, with man most frequently infected from animals.

Every infectious disease has not only characteristic clinical manifestations but also its own specific way of invasion into the human body.

Such a disease as dysentery ['disntn], which is one of the diseases of the intestinal infections, is spread through the intestines and stools.

The infections of the respiratory tract compose the second subgroup. Dur­ing coughing or talking the pathogens are discharged from the infected organ­ism with the mucus from the membranes of the respiratory tract into the air in the form of drops. The infection is spread when the air containing drops of mucus with the pathogens in it, is breathed in. The diseases of this subgroup are diphtheria, smallpox, etc.

The diseases of the third subgroup are spread through the skin and the mu-cosa in which the pathogens multiply. In some cases it is the skin, in others it is the mucous membrane of the eye. Direct contact and various things belonging to the sick may be responsible for spreading the infective agent.

The diseases of the fourth subgroup are spread by living insects. The patho­gens causing these infections circulate in the blood or lymph and are not dis­charged from the organism. The insects become infected as they ingest (сосут) the blood of a diseased man. They become infectious for other people after the pathogens have multiplied in their organism. All these diseases, of which en­cephalitis [m,sef3'laitis] is an example, are called blood infections.
