Is traveller’s diarrhea inevitable?
How do I tell if my traveller’s diarrhea is serious?
If symptoms last more than a week  or your condition worsens, you should seek medical attention immediately in these situations:
- Severe abdominal pain
- Bloody or black stools
- Fever over 39 °C 
A part of the diagnostic process involves determining whether an uncommon bacteria or parasite is present in the body. Most diagnostic sessions focus on identifying fecal bacteria or parasites. There are many viruses that cause diarrhea, but they are traditionally very difficult to identify. Usually, stool cultures for bacteria or parasites are labour-intensive and must be repeated three times.
Coping with post-travel blues
Even if your vacation was very enjoyable (and perhaps even more so in this case), you may still experience mild depression after you return home.
Post-travel blues (In French) is a genuine ailment and a common consequence of returning home. Although it usually resolves within a few days, post-vacation depression tends to be more pronounced following long stays away.
It is accompanied by symptoms similar to those of seasonal depression, such as:
- Lack of energy
- Difficulty concentrating
- Loss of appetite
- Trouble sleeping
