Hello,
my name is Laura Harrington
and I'm a professor of
entomology at Cornell
University in Ithaca, New York.
My research focuses on the biology
and behavior of disease vectors.
Today I'm going to tell you
more about the epidemiology
of vector borne infections.
0:24
Before we begin I would like to tell
you about some additional topics
that would be useful to review
before you listen to this lecture.
In particular, I'd like
you to review the lectures
on the transmission of
vector borne infections.
Also review the
lectures on arboviruses
and the biology of malaria.
We'll be using examples
of arboviruses and malaria
to highlight epidemiology
in this lecture.
In addition, this lecture will focus
on biologically transmitted agents.
Although there are other
modes of transmission,
we will not be covering
those modes, including
mechanically transmitted agents.
1:10
Here's an outline for
the lecture today.
I'll begin with an introduction
to the field of epidemiology,
including definitions
of epidemiology
and a discussion of
why epidemiology is
important in the study of
vector borne infections.
I'll then provide you with some
examples of the different types
of determinants, or factors, that
influence disease transmission.
We will then go into several
different important epidemiological
measures which are
used by epidemiologists
to study vector borne infections.
I'll then present some examples of
field based epidemiology, including
the steps in investigating
a disease outbreak,
as well as the steps in
vector incrimination.
I'll conclude with a review,
including several questions for you
to think about within the
context of today's lecture,
as well as some useful
references for further reading.
