Traveler's Diarrhea (cont.)

Is Traveler's Diarrhea Contagious?

Yes, no matter what the pathogenic cause (bacterial, viral or parasitic, see above) traveler's diarrhea is contagious. The vast majority of individuals obtain the pathogens by orally ingesting them. Common routs that lead to oral ingestion are by eating food or drinking water contaminated with the pathogens. Pathogens also survive sometimes for days on surfaces such as handrails, doorknobs, computer keys, children's toys, and many other similar items. The pathogens are then transferred to the mouth by a person simply touching their face on or near an oral mucosal area (lips, tongue, gums, teeth, for example).
