DIARRHEA
IN
TRAVELERS
Persons who travel from highly
industrialized
regions
to
developing
countries
commonly experience
diarrhea.
The frequency is approxi-
mately 40% and varies slightly accord-
ing to
the
country
visited.
The typical
course for untreated illness consists
of
the pasage
ol
12-13 stools over a
5-
day
period.
Food probably
is
the
ma-
jor
source
ol
infection for those
travel-
ling
to
large
cities although water
un-
doubtedly
plays
a
role especially
after
heavy
rainfall has
occurred.
The
ma-
ior
causative organisms
are
enterotoxigenic
E.
Coli,
rotavirus, and
giardia
etc.
Since bacterial agents are
the most common causes (accounting
for between 60-70% of cases), antimi-
crobial agents have been used suc-
cesslully
in
the prevention and treat-
ment of
the
illness.
