The case of Andrew Speaker, the Atlanta man who flew back and forth to Europe last month despite having a dangerous strain of tuberculosis, makes business travelers wonder just how risky it is to breathe in the confined space of an airplane cabin. Since you have no choice about breathing, and you need to travel to do your job, we suggest you take a deep breath and relax — but only if you’re not sitting close to someone with a hacking cough. We know from personal experience that you can come down with a nasty case of the flu two days after being jammed against the window of a 737 for six hours, surrounded by coughing and sneezing members of a college baseball team.
Here’s what happened in Speaker’s case: He was found to have a rare, extremely drug-resistant strain of TB. Officials at the Centers for Disease Control and Prevention told him they “preferred” he not take a planned wedding-and-honeymoon trip to Europe, but they did not order him to stay home. He felt fine and had no TB symptoms, such as a cough. He made the trip, flying Air France from Atlanta to Paris, then took more flights within Europe before returning two weeks later on Czech Air from Prague to Montreal. He drove a rental car back into the country near Plattsburgh, N.Y., where a border-control officer thought he looked healthy and welcomed him home. He is now in isolation in a Denver hospital.
Here’s the important part for those concerned about exposure to TB or any other airborne illness while flying. Following World Health Organization guidelines, the CDC is recommending passengers on Speaker’s flights who were sitting in his rows or in the two rows behind or ahead of him, as well as flight-crew members, be evaluated for TB infection. That proximity to what the CDC calls “the index patient” is among several important considerations when assessing risk for catching a bad bug on an airplane, says Myles Druckman, a physician who’s medical assistance director for International SOS. The company is one of the world’s largest medical-assistance companies for travelers and has its North American headquarters in Philadelphia.
“Any time you get a group of people from around the world in a confined space for hours, there’s a risk, and that includes on a train or in a room,” Druckman said. In fact, he said, the air in an airplane cabin usually is cleaner than that in the average building because it is filtered as it is drawn in and recirculated. In most cases, gettting sick from airplane air happens only on very long flights and to those sitting within five or 10 rows of someone who is coughing, according to Druckman. “On any flight of less than eight hours, the risk is very, very low,” he said.
Druckman and other experts recommend travelers use common sense: If you’re sick, stay at home to avoid exposing others or getting worse yourself. If you have to cough, bury your face in your sleeve or otherwise cover your mouth. Wash your hands frequently.
If you’re healthy and ready to go, you should arm yourself with knowledge about the risks of traveling to particular parts of the world where infectious diseases are endemic. Many companies with employees who travel internationally have gotten much better in this area because of the Sept. 11, 2001, terrorist attack, and warnings that started about two years ago about avian flu in Asia. Companies and other organizations now keep better track of where their travelers are and provide information about threats — health or otherwise — for the places they send their people.
