Throughout the centuries-old history of the AP, there has been no evidence of the contagiousness of this disease and the danger of its transmission from a sick person to a healthy one. People who became ill with AP were not subjected to isolation and other precautions necessary for infectious processes. There was only a certain seasonal difference in the frequency of this disease, but no epidemics of AP were observed.

The development of microbiology, which originated much earlier than the appearance of antibiotics, did not affect the image of the AP in any way. This disease was still regarded as acute inflammation. With the discovery of Streptococcus pneumoniae more than 140 years ago, it was found that it is the most frequent causative agent of AP, as a result of which it received the meaningful name "pneumococcus" [1]. However, along with pneumococcus, inflammatory processes of the lungs could occur with the participation of other microorganisms, so for a long time the microbiological and pathological essence of the disease was precisely concentrated in the term "acute nonspecific inflammation of the lungs". In this name, the word "nonspecific" emphasizes the absence of a pathogen specific only to AP, as well as the fact that strains of microbes involved in inflammation of lung tissue can be found among symbionts in healthy people [2].
