History of Infectious Diseases

Infection 感染
the invasion of the body by any of
various infectious agents – including
bacteria, viruses, fungi, protozoan
and worms and the reaction of the
body to them or their toxins.
Definitions

Infectious disease 感染病 (cause)
The disease caused by infection and/or capable being communicable by
infection

Communicable disease 传染病 (transmission)
The disease capable of being transmitted from one person to another or
from animals (intermediate host) to human.

Epidemic disease 流行病 (incidence)
The occurrence of cases of disease in excess of what is usually expected for
a given period of time. (epidemic hysteria)

Endemic disease 地方病 (location)
The disease that is constantly present in people living in a particular
location (endemic thyroid disease-goiter)
Human and Infectious Diseases

Epidemics 流行
Sudden outbreak of diseases in excess of
what is expected

Pandemics （全球）大流行
Sudden geographically widespread
outbreak of diseases
History of Infectious Disease

Prehistoric period：Infectious disease rare

Agriculture society：Increased transmission

Urban civilization： Congestion of urban inhabitation, war
and travelling result to outbreak of infectious diseases
Three factors of
transmission of
infectious disease
•Source of infection
•Susceptible population
•Transmission routes

Inspired by the fact that
dairymaids infected with cowpox
were immune to small-pox,
Edward Jenner invented cowpox
vaccine against human smallpox.

Jenner deliberately infected
James Phipps, an eight year
old boy, with cowpox in May
14, 1796. He then exposed
Phipps to smallpox–which
Phipps failed to contract. After
repeating the experiment on
other children, including his
own son, Jenner concluded
that vaccination provided
immunity to smallpox without
the risks of variolation.
Jenner’s findings were
published in 1798.

Caused by Influenza virus strain

estimated 20 to 100 million people
were killed (mortality rate 2.5-5%)

绿水青山枉自多，华佗无奈小虫何！
千村薜荔人遗矢，万户萧疏鬼唱歌。
坐地日行八万里，巡天遥看一千河。
牛郎欲问瘟神事，一样悲欢逐逝波。
春风杨柳万千条，六亿神州尽舜尧。
红雨随心翻作浪，青山着意化为桥。
天连五岭银锄落，地动三河铁臂摇。
