Hello, my name is
Laura Harrington and
I am a Professor in
the Department of Entomology at
Cornell University in
the United States.
Today, I will be presenting
a lecture on epidemiology.
I'll present this course in
the context of
vector-borne diseases.
0:22
Before you view this lecture,
please review the lectures
on vector-borne
disease transmission,
as well as those on the biology
of arboviruses in malaria.
I will assume that you have
some baseline knowledge
on these topics.
Today I'm going to focus just
on biologically
transmitted agents.
Keep in mind that mechanically
transmitted agents and
other modes of transmission are
important but will
not be covered.
I also will not cover
outbreak investigation.

Here is an outline of my
presentation for today.
I'll begin with an
introduction to
the field of epidemiology.
We'll then discuss
determinants of disease.
Then I will cover
general and vector-specific
epidemiological measures
including mosquito and
tick infection rate.
I will then share
some field-based applications of
epidemiology and then I will
conclude with a review
and some references
for further reading.

Here are the learning
objectives for this lecture.
At the end of my presentation,
you should be able to define
epidemiology and
describe why it is
important and understand
the common terms
used in epidemiological
practice.
I expect that you will be able
to understand the difference
between normal endemic
disease cycles and
epidemic disease. And
you should be able to
calculate vector-borne
disease measures,
described how they
are important,
and determine when to apply
each measure. And I will be
presenting a range of
different measures today.
I also expect that
you'll be able to
describe different
data represented by
measures of morbidity and
mortality and consider
the complexity of
factors or determinants
that influence
vector-borne disease
transmission. And lastly,
you should be able to compare
and contrast approaches to
estimating disease risks and
how they are used operationally.
