Global airlines move to reduce infection risks
By Karen Jacobs
China Southern Airlines has been disinfecting the cabins of all aircraft. China Eastern Airlines flight attendants are required to wear disposable facial masks, gloves and hats and even disposable overcoats during flights to select destinations. Mexicana Airlines uses high-efficiency filters that can trap small particles that would normally recirculate back into the air, spokesman Adolfo Crespo said. The H1N1 flu virus has been confirmed in 20,000 people in 68 countries, killing at least 126, according to the World Health Organization. Although it appears mild, experts worry that the disease, which formerly was called "swine flu," could change into a more dangerous form. In the wake of the spread, some countries have intensified health precautions.
The government quarantined the passenger and about 60 other people on the same flight who were sitting within three rows. "This won't be the last case in

In contrast to the measures taken by Asian airlines,
Atlanta-based CDC has not recommended that airline crews wear face masks or disposable overcoats.
"The issue with H1N1 and airlines is an issue of translocation, not necessarily on-board transmission," Shelly Sikes Diaz, a CDC spokeswoman, said in an email. She added that people were no more likely to catch the flu on a two-hour plane flight than they were sitting next to someone for a two-hour movie.
"Therefore, at this time, recommended on-board infection control measures would be similar to community infection control measures" such as frequent hand-washing, Diaz added.
David Castelveter, a spokesman with the Air Transport Association trade group, said
"We take our guidance from the professionals (such as the CDC) who tell us the precautions that are needed to prevent the spread," Castelveter said. "We're not taking the type of precautions that are unnecessary." While Castelveter said media coverage of the flu has boosted awareness of airline safety procedures, Mexicana's Crespo stressed that carriers still have work to do to change public perceptions that air quality on planes is bad. "Inside, our aircraft is cleaner than in a hospital," Crespo said.

He said safety measures such as costly air filters may be of limited use for carriers.
"This is because most of the transmission between passengers probably mostly occurs just after the sneeze/cough in the immediate vicinity of the passenger rather than after it flows through the ventilation/circulation system and back out again," he said.
