Travelers sickness can have various causes, just like most other symptoms. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose travelers sickness, we could:

→ Yes, but symptoms resolved completely
→ Yes, long-term symptoms finally resolved
→ Yes, symptoms still present, partially resolved
