DIANE
SAWYER (ABC NEWS)(OC): And, you may have seen a headline today about your
health that has created a
lot of interest,
a lot of concern
and confusion,
an article in a leading medical journal about a little known disease caused by
a small insect. The
journal compared
it to the new HIV, AIDS. It's called
Chagas disease, and there are 300,000
known infections
here in the US but what is the real risk for everyone else? We asked ABC's medical editor Dr Richard
Besser for a reality check.
DOCTOR
RICHARD BESSER (ABC NEWS)(VO): The alarming headline, a frightening, mysterious
disease, but not here. The disease is
called Chagas. You get it
from this tiny
parasite,
carried
by a one-inch long bug,
sometimes called a kissing bug, because it likes to bite you near the
mouth. If it bites you near your eyes,
they'll turn puffy,
a warning sign.
DOCTOR
RICHARD BESSER (ABC NEWS)(VO): But all too often, there's
no sign you've been infected. For decades, it
can lie dormant
in your body until suddenly, destroying your heart. In Latin America, it infects the
destitute. Living in homes
with mud
walls and
thatched
roofs,
where the bug is mostly found. In the
US, those infected are
immigrants
who pick
it up in
their home
countries,
but a
big reality
check.
DOCTOR
RICHARD BESSER (ABC NEWS)(VO): Despite comparisons to HIV, you can't get Chagas
from another person, period. And the
kissing bugs in America are a different kind of bug.
DOCTOR
RICHARD BESSER (ABC NEWS)(OC): You know, Chagas is a disease that needs
treatment and attention. Those people in
America who already have it have to be diagnosed and taken care of. But the real fight against this
tropical
disease
is in Latin America where it is really running rampant.
DIANE
SAWYER (ABC NEWS)(OC): And you track diseases, we should tell everybody, for the
CDC. Tell us, again, about this bug
in North America?
DOCTOR
RICHARD BESSER (ABC NEWS)(OC): That's right.
You know, I spent years at the CDC, tracking infections. And the
disease detectives
need to keep their eye on this. But this
particular bug and the way it spreads infections is only found in Latin
America, not here in America.
DIANE
SAWYER (ABC NEWS)(OC): Okay, we saw a lot of alarm today when people read that
headline.
DOCTOR
RICHARD BESSER (ABC NEWS)(OC): That's right.
DIANE
SAWYER (ABC NEWS)(OC): Thanks so much, Rich.
