Mortality from croupous pneumonia equals approximately 20% (Sokolovsky), in Leningrad hospitals from 20.5 to 22.8%; in Moscow hospitals - 21.8 to 23.7%; for Warsaw 24.4%, Kazan 16.7%; (Zimnitsky), according to the Yakutsk Regional Hospital for 1925 17.6% for 1926 25%, an average of 21.3%. Not surprisingly, doctors are looking for a treatment that would reduce mortality, shorten the duration of the disease, and moderate the severity of the symptoms.</p>Kazan Medical archiveКазанский медицинский архив
