Whether taking a cruise or flying to an exotic location, you can be proactive
to ensure a fun, relaxing trip, as well as a healthy, safe one.
“No one wants to think about getting sick or hurt during a trip,
but sometimes these things happen,” points out
Dr. Stacy Newman of North Oaks Infectious Disease Clinic.
As a frequent traveler to exotic locations, she speaks from experience.
During a trip to East Timor in 2003, she acquired dengue, a mosquito-borne
tropical disease that causes fever, headaches, muscle and joint aches,
and skin rashes. Although no vaccination is available for dengue, Dr.
Newman notes that taking proper precautions and preventive measures can
help protect travelers from secondary infection.
“It just takes one mosquito (to relay the disease),” she adds.
“I was lucky that I was sick for only 3 weeks. The symptoms can
last anywhere from 1 week to a couple of months.”
When traveling, Dr. Newman recommends carrying your prescription drugs
with you instead of packing them, drinking plenty of fluids and getting
your rest. But, most importantly she warns, be sure to visit your physician
“Before leaving on an extended trip or traveling in areas where there
is a chance you could contract a life-threatening disease, make sure your
vaccinations are up to date,” she suggests. “Whether you’re
going to Afghanistan or Zimbabwe for military or contract work or to Brazil
for a soccer tournament, we have an extensive database which can access
health risks and advice for any international destination.”
Dr. Newman believes it’s a good idea to know beforehand the signs
and symptoms of illnesses. This helps travelers recognize a sickness and
take action quickly while on a trip that requires traveling by air or boat.
Dr. Newman suggests familiarizing yourself with the following tips and
Airplane travel, especially longer than 8 hours, may increase the risk
for blood clots, known as Deep Vein Thrombosis/Pulmonary Embolism (DVT/PE).
Because the air pressure in flight is lower than at sea level, the amount
of oxygen carried in the blood is lowered. Certain medical conditions,
like heart and lung disease, may not be able to tolerate the reduced oxygen level.
Include insect repellent on your packing list and use on uncovered skin
when outdoors. Wear a long-sleeved shirt and long pants when outdoors,
especially in areas with malaria.
Food and water contamination
Wash your hands often with soap and water, especially before eating or
preparing food and after you use the bathroom, cough or sneeze. In some
countries, you should only drink bottled or boiled water or carbonated
drinks in cans or bottles. Avoid tap water, fountain drinks and ice cubes.
Do not handle or pet animals, especially dogs and cats. If you are bitten
or scratched, wash the wound immediately with soap and water and seek
Use caution when swimming and participating in water activities. Only swim
in chlorinated pools. Do not swim in freshwater in developing areas or
where sanitation is poor. Be aware of local weather conditions and watch
for large waves, strong tides and rip currents.
Traveling on cruise ships exposes people to new environments and high volumes
of people, Dr. Newman notes. The exposure can create the risk for illness
from contaminated food or water or through person-to-person contact.
“Wash your hands often. If you see someone get sick, leave the area
and report it to a crew member immediately,” she shares. “And,
always drink plenty of water.”
If you do become sick while traveling, Dr. Newman urges you to get to a
doctor right away.
