Illness
People get sick no matter where
they are in the world. Routine illnesses such as colds and the flu are common.
Some
illnesses that can be produced by travel are of particular concern:
| • |
Gastrointestinal illness
(especially diarrhea diseases)
|
| • |
Altitude sickness
(usually benign, occasionally serious)
|
| • |
Infectious diseases
|

|
The risk of acquiring an infection varies greatly, depending on the country and region traveled to. Influenza, for example,
is a problem in
the southern hemisphere during our spring and summer and may
be present throughout the year in the tropics.
Illness
can also occur due to pre-existing health problems
aggravated by travel (especially heart
and lung conditions).
Post-travel
illness can also occur. Diarrhea is the most common
illness reported by travelers who have recently
returned from other countries.
