[00:02.37]Unit21 Human BiologyLesson3 Epidemics Explained

[00:09.57]Epidemics throughout history

[00:12.34]With new health threat on the rise,

[00:14.33]James Madison looks at epidemics

[00:16.13]throughout history.

[00:18.09]Bacteria and viruses have been around

[00:20.34]since the beginning of life

[00:21.78]on Earth and many of today's diseases

[00:24.10]have existed as long as humans have.

[00:27.33]It's important to look at the spread

[00:28.88]of diseases throughout history to discover

[00:31.24]the causes and effects of epidemics.

[00:34.41]Epidemics are described in historical accounts

[00:37.13]as early as 430 BC

[00:39.87]and one of the earliest on record

[00:41.68]is Justinian's Plague.

[00:43.62]It happened about 500-550

[00:47.64]as Roman Emperor Justinian

[00:49.87]was attempting to rebuild and acquire more land

[00:52.47]for the Roman Empire.

[00:54.03]It swept through North Africa,

[00:55.71]the Middle East and Europe.

[00:58.15]Scientists now think taht Justinian's Plague

[01:00.83]was actually a disease called bubonic plague.

[01:04.34]They estimate that between 25% and 50%

[01:07.95]of the area's population died

[01:10.08]from the disease and think that the epidemic

[01:12.34]was one of the key causes

[01:13.70]of the fall of the Roman Empire.

[01:14.91]
