Public Health II - lectures

17.2. Infectious Disease Epidemiology - introduction.

ANNOTATION


Infectious disease epidemiology historically formed the main principles of epidemiology as we know them now. The investigation of epidemics and the need for preventive measures required specific approaches to diseases using descriptive and analytic methods. The ongoing pandemic reminded us of an underestimated fact that humans are still only a part of nature and stay still a vulnerable member in the dynamic world of infections. Knowledge in the field of epidemiology of infectious diseases is still a basic knowledge of a doctor. A lack of knowledge in this area can be a threat to both individuals and public health.

This lecture introduces us to general infectious disease epidemiology.

"Mass of Separation"  for lepers (13th. century)  First anti-epidemic measures? 

"I forbid you to ever enter the church, monastery, a fair, a mill, a market or an assembly of people. I forbid you to leave your house unless dressed in your recognizable garb and also shod. I forbid you to wash your hands or laundre anything or to drink at any stream or fountain, unless using your own barrel or dipper. I forbid you to touch anything you buy or barter for until it becomes your own. I forbid you to enter any tavern, and if you wish for wine, whether you buy it or it is given to you, have you funnelled into your keg. I forbid you to share a house with any woman but your wife. I command you if accosted by anyone while travelling on a road, to set yourself downwind of them before you answer. I forbid to enter any narrow passage, lest a passerby bumps into you. I forbid you, wherever you go, to touch the rim or the rope of a well without donning the gloves. I forbid you to touch any child or give them anything. I forbid you to drink or eat from any vessel but your own." link for the source
