ATLANTA_SARS on a plane. Mumps on a plane. And now a rare and deadly form of tuberculosis, on at least two planes.
Commercial air travel's potential for spreading infection continues to cause handwringing among public health officials, as Tuesday's news of a jet-setting man with a rare and deadly form of TB demonstrates.
"We always think of planes as a vehicle for spreading disease," said Dr. Doug Hardy, an infectious disease specialist at UT Southwestern Medical Center in Dallas.
In the latest incident, reported by health officials on Tuesday, a Georgia man with extensively drug-resistant TB ignored doctors' advice and took two trans-Atlantic flights, leading to the first U.S. government-ordered quarantine since 1963.
The man, who officials did not identify, had been quarantined at Atlanta's Grady Memorial Hospital until Thursday morning, Grady Memorial Hospital spokeswoman Denise Simpson said. Neither Simpson nor William Allstetter, spokesman for National Jewish Hospital in Denver hospital where the man was expected to be taken for treatment, would confirm if he was transferred there.
Dr. Charles Daley, head of the infectious disease division at National Jewish, which specializes in respiratory disorders, also could not confirm the man's whereabouts, but he said the hospital has treated two other patients with what appears to be the same strain of tuberculosis since 2000 and both improved enough to be released.
"I think we're more optimistic than what we have been hearing in reports that we will be able to control this infection," Daley told CNN Thursday morning. "We're aiming for cure. We know it's an uphill battle."
The patient was not considered highly contagious, and there are no confirmed reports that his illness spread to other passengers.
But his case illustrates ongoing concerns about the public health perils of plane travel, as well as the continuing problem of Typhoid Mary-like individuals who can almost be counted on to do the wrong thing.
The man decided to proceed with a long-planned wedding trip despite being advised not to fly. "There's always going to be situations where there is a lack of understanding and appreciation of responsibility to the community in a situation like this," said Dr. John Ho, an infectious diseases specialist at New York-Presbyterian Hospital/Weill Cornell Medical Center.
The incident also points out weaknesses in the system: The man was able to re-enter the United States, even though he said he had been warned by federal officials that his passport was being flagged and he was being placed on a no-fly list.
CDC officials said they contacted the Department of Homeland Security to put the man on a no-fly list, but it doesn't appear that was accomplished by the time he flew from Prague to Montreal and drove across the border from Canada.
A Transportation Security Administration spokesman could not immediately be reached for comment on Wednesday morning.
Challenges in coordination with airlines and in communicating with the media also have emerged, said Glen Nowak, a spokesman for the U.S. Centers for Disease Control and Prevention.
"This clearly is going to have some relevance to our pandemic influenza preparedness," Nowak said.
There have been several prominent disease-on-a-plane incidents in recent years.
Perhaps best known is severe acute respiratory syndrome, or SARS, which erupted in Asia in 2003. Over three months, CDC workers delayed on the tarmac 12,000 airplanes carrying 3 million passengers arriving from SARS-affected countries, and isolated people with SARS symptoms.
