VECTOR-BORNE DISEASES:
What are they?
Illnesses transmitted by
mosquitoes, ticks, fleas, and other insects.
These diseases include chikungunya,
dengue fever, malaria, and others.
Why do they affect travelers?
They
don’t affect travelers per se, but rather are
endemic to certain areas of the world.
What to do:
Find out whether your travel
destination carries a risk for vector-borne
disease and take appropriate precautions,
which may include vaccination, insect
repellant, or avoiding certain behaviors or
environments.
QUICK TIP:
Research any endemic diseases or special conditions to which you may be exposed, especially
if you plan to travel internationally. These can range from malaria to heat stroke. The Centers for
Disease Control and Prevention (CDC.gov) is a great resource for comprehensive information on
current alerts and common diseases in your destination.
FLYING AFTER DIVING
Flying to a destination near sea level before diving poses virtually no risk. Flying after diving, however,
increases decompression stress, since the pressure in an aircraft cabin is lower than ground-level
atmospheric pressure. DAN recommends you follow these guidelines when traveling:
Please remember that any postdive ascent to a higher altitude – even using ground transportation –
increases your decompression stress.
