The first thing I want to say is
that there's a thesis to the course,
that you don't have to share,
but that I'd like to test
for the next twelve or thirteen weeks.
And that thesis is that infectious diseases
are too important to leave solely to the doctors.
Epidemics, in other words, have had an impact on history
换句话说 流行病 我认为
that I would regard as equal to that of revolutions,
wars and economic crises.
They are part of the big picture of historical change,
and not some exotic special interest.
Epidemic diseases have had an enormous impact on religion,
on the arts, on the colonial expansion,
on the establishment of New World slavery,
on the rise of modern medicine,
and on strategies of public health.
To examine this thesis,
we won't be looking at all diseases.
We'll be looking only at a subset
of high impact infectious diseases
that have affected Europe and North America.
So this means certain exclusions.
We won't be looking at chronic diseases, such as cancer,
heart disease, diabetes, asthma, obesity.

We won't be examining occupational diseases
such as miner's lung or asbestosis.
We'll eliminate also a whole range of tropical diseases
that haven't had a major impact on the industrial West,
such as dengue, or sleeping sickness,
or Chagas disease.
All of these, and other diseases,
I would agree entirely are important and worthy of study,
but it would take far more than a semester to examine them all,
and lumping all diseases together
would lose all coherence.
Epidemic diseases-- that is, high impact,
infectious diseases make sense intellectually
as a separate category of analysis.
That is to say they were, and still are,
experienced differently from chronic disease,
and give rise to distinctive fears and anxiety.
As you can see in your own day,
having heart disease can be a frightening
and even a lethal experience.
But it's qualitatively distinct
