Document Summary
Life comes from other life and disease comes from germs (and a few other things). Despite the use of putting red wine in bandages to prevent infection early in the second millennium in salerno italy etc, the thought of the time via aristotle, was diseases rose spontaneously. In 1668, redi demonstrated that maggots come from flies and do not arise spontaneously. It took about 200 more years, with the work of pasteur and others, to remove all doubt that disease arose via biogenesis and not abiogenesis. Koch presented some postulates to confirm that disease came from germs. This was another great step forward in medicine despite the postulates not being applicable universally (e. g. , do not apply well to viral infections). Nowadays koch"s postulates have been replaced with a few more steps and genetic sequencing: infectious diseases. A disease is any deviation from normal functioning. An infectious disease is a disease in which a pathogen is present and may multiply.
