Traveller Diarrhea

I have Traveller's diarrhea. When should I see a Doctor

Traveler’s Diarrhea is the most common illness that affects travelers. It is spread easily from person to person or by consuming contaminated food or water. It is caused by many diferent bacteria (including E. coli, Salmonella, Shigella and Campylobacter), parasites (including Giardia, Crytosporidium, Cyclospora and others) and viruses (such as norovirus and rotavirus). Unfortunately, it is very common among travelers in Asia.


Traveler’s Diarrhea usually begins abruptly during your trip or shortly after you return home, some cases improves within one to two days without treatment and clear up completely within a week. However, if you have 2- 3 in any of these symptoms, you might need to seek a professional attention.

Immediate Diagnostics

Blood Test

A complete blood count can show signs of infection, anemia, inflammation, or imbalances of electrolytes, to help determine the cause of your diarrhea.

Stool Test

This might be recommended to determine whether bacteria or a parasite is causing your diarrhea. A healthcare professional will give you containers for catching and storing your stool samples, as well as instructions on where to send or take the containers for analysis.
