Welcome to our
study of surveillance, prevention,
and control of
My name is Jonathan Day.
And I'm a professor of medical
entomology at the University
of Florida, Florida Medical
And I will be your guide
through this module.
We will use five
model systems for our discussion.
Certainly, there are many
other vector-borne diseases
that we could discuss.
But our focus in this module
will include these five disease
systems-- St. Louis encephalitis
virus in Florida, dengue
and Chikungunya viruses in Florida,
West Nile virus in North America,
and finally, Eastern
equine encephalitis virus
in North America.
We will begin our study by asking
the question, what is the purpose
And first, we'll talk about
vector-borne pathogen detection.
The first purpose of
vector-borne disease surveillance
is to detect a new virus or a
reintroduced virus in an area.
As you can see from
this 2002 news clip
from the Stuart News
in Stuart, Florida,
there are a number of different
ways that scientists look
for the reemergence
of a virus in an area
where it's known that that
virus occurred previously.
In this case, they're talking
about sentinel chickens, the use
of sentinel chickens, and the use
of tracking meteorological events
to forecast virus transmission.
So surveillance techniques-- and
we'll get into these surveillance
techniques in detail later in the
module-- surveillance techniques
allow the identification of
the emergence or reemergence
of a vector-borne disease
in a particular area.
