Travelers
Diarrhea
The
most common cause of travelers' diarrhea, usually a
self-limited illness lasting several days, is infection
with
noninvasive enterotoxigenic
(ETEC) or enteroaggregative (EAEC)
strains of Escherichia coli
.
Campylobacter
,
Shigella , Salmonella
, Aeromonas , viruses
and parasites are less common.
(See
individual links at travelers diseases.
Children
tend to have
more severe illness and are particularly susceptible to
dehydration. Travelers to areas where hygiene is poor should
avoid raw vegetables, fruit they have not peeled themselves,
unpasteurized dairy products, cooked food not
served steaming hot, and tap water, including ice.
Treatment
– For
mild diarrhea, Imodium (4-mg
dose, then 2 mg orally after each loose stool to
a
maximum of 16 mg/d for adults), relieves symptoms
. It should not be used if fever
or
bloody diarrhea are present, and some haveconstipation after use.
If
diarrhea is moderate to severe, persistent or
associated with fever or bloody stools, self-treatment
for
1-3 days with a broad spectrum abtibiotic (quinpolone or macrolide
class prescribed by a doctor) is
usually recommended.
Packets
of oral rehydration salts
mixed in potable water can help maintain electrolyte
balance,
particularly in children .
.
No truevaccine exists (the product Dukoral has an effectiveness
of 20% and is not a true travelers diarrhea vaccine) yet but antibiotics
can be taken for self treatment abroad.
