Clasification of infectious diseases In the 19th centure infectious diseases were classed as contagious transmissible from person

Later the diseases were classified according to their aetiology The Clasification based on clinical ang epidemiologic signs proved infective too. In accordance with the main sign That determine the transmission mechanism, all infections

diseases are divided by the Gromashevsky into four groups:

1. Intestineal infections2. respiratory infections3. blood infections4. skin infections

Infecting agents /disease-producing germBacteria, virus, protozoa, rickketsia, fungus (FUNGI), prions, spirochetes
