Web Letter for Passengers
XDR TB in Traveler
Dear Passenger or Flight Crew Member:

A person with extensively drug-resistant tuberculosis (XDR TB) traveled on an airline flight you may have taken in May 2007:

Date  From  To  Airline / Flight#
May 12/13 Atlanta, Georgia Paris, France Air France #385 // Delta #8517
May 24 Prague, Czech Republic Montreal, Canada Czech Air #104

Tuberculosis (TB) is a disease caused by germs that are spread from person to person through the air. TB and XDR TB are spread the same way, but XDR TB is resistant to almost all of the drugs commonly used to treat TB disease. The general symptoms of TB disease include cough, weight loss, fever, and night sweats. When a person with TB disease of the lungs or throat coughs, sneezes, or speaks, TB germs may be expelled into the air and can remain airborne for several hours, depending on the environment. Persons who breathe the air containing these TB germs can become infected; this is called latent TB infection (LTBI).

This is the first investigation of a case of XDR TB during air travel. Due to the serious nature of this strain of TB disease, CDC is recommending that all U.S. residents and citizens on either of these flights receive evaluation and testing for TB infection. Passengers who were most at risk were those sitting two rows in front and two rows behind the patient.

If you were a passenger or flight crew member on either of the two flights listed above, we strongly recommend that you complete these steps at your earliest convenience:

See your physician or local health department and request TB testing. Bring documentation of travel history for the flight and health history with you.

Receive TB testing, which should include an evaluation of signs and symptoms of TB, a TB skin test or the QuantiFERON®TB Gold blood test (QFT-G) to test for TB infection, and possibly a chest x-ray.

If needed, return to your healthcare provider for a second TB test 8?10 weeks following your flight date (i.e., the time of your last possible exposure to the patient).

Keep a copy of your test results for your records. If you ever experience any signs or symptoms of TB disease in the future (regardless of your test result), see a physician promptly and explain that you were possibly exposed to a person with XDR TB.

Many persons born outside of the United States receive a vaccine called BCG (Bacille-Calmette Guerin) to prevent development of TB disease; however, we still recommend that persons who received BCG vaccination should be tested for TB.

For inquiries related to this investigation or questions regarding payment for TB testing, please go to State TB Control Offices.

Questions and Answers: XDR TB in Traveler
From May 30, 2007 CDC Press Conference

What is extensively drug resistant tuberculosis or XDR TB?

XDR TB is a rare type of tuberculosis that is resistant to nearly all drugs used to treat TB disease.

What happened?

CDC is currently investigating a case of extensively drug resistant tuberculosis (XDR TB).   The case involves a U.S. citizen with potentially infectious XDR TB who traveled to and from Europe on commercial flights between May 12 and May 24, and then re-entered the U.S. at the Canada-U.S. border via automobile.  Since May 25, the patient has been hospitalized in respiratory isolation and is undergoing additional medical evaluation.

Why did the patient travel?

Normally, when a patient has tuberculosis, he or she is influenced through a covenant of trust to ensure that they don't put themselves in situations where they could potentially expose others. In this case, the patient had compelling personal reasons for traveling and made the decision to go ahead and meet those personal responsibilities.

How did the patient return to the United States and then Georgia?

On May 12, the patient departed Atlanta on and arrived in Paris on May 13 on Air France flight 385. The patient flew to Canada on Czech Air flight 0104 and then entered the United States by car on May 24.

It was not safe for the patient to fly on commercial aircraft, so government resources were used to bring the patient from New York back to Georgia in the safest and quickest possible way. In New York, the patient was put into isolation fairly soon after his arrival and was later flown to Georgia, his state of residence on the CDC aircraft, a step that we were not obligated to take under our quarantine authorities, but one that we felt was fair and appropriate given that he is a citizen of Georgia. His family members are here and his disease does require prolonged treatment.

Did the patient know he had TB before he got on these flights?

Our understanding from the county health officials, who were responsible for managing the patient when he initially presented with TB, is that he was aware of his diagnosis. When he departed, he may not have been aware of the fact that he had extensively drug resistant tuberculosis.

Where did the patient become infected with the extensively drug-resistant (XDR) TB?

The source of the patient's TB is still under investigation. CDC is conducting something called an Epi Aid, which means our epidemic intelligence service officers are actively participating and investigating not only opportunities for exposure to passengers, crew, family members, or others but also looking backward to try to determine where the original infection occurred that is an ongoing investigation.

Why was a federal order of isolation issued?

After the patient had left the jurisdiction, the TB organism was identified as extensively drug resistant. A federal order of isolation under the Public Health Service Act that gives CDC statutory responsibility for issuing quarantine orders was executed to protect the public.

This patient was ordered to be in isolation and is required to stay in isolation until the responsible public health official deems that he is no longer infectious to others. The patient currently is isolated and is undergoing medical evaluation.

Under what circumstances was the federal isolation order executed?

After speaking to CDC authorities, the patient voluntarily drove himself to the isolation hospital in New York City to be evaluated. He was given instructions on how to do that safely without putting public health at risk. He was admitted and served a provisional quarantine order that held for 72 hours while this assessment was going on. The patient was asked if he preferred to remain in New York City for his treatment or if he wanted to come home to Atlanta. He preferred to come home and we ensured the safe transport for that return to Atlanta on Monday via the CDC plane.

He was issued a federal isolation order on arrival in Atlanta to cover the period of time for us to hand over the jurisdiction and public health management of this case to the state and local authorities in Fulton County in the State of Georgia where he is a resident.

The order is in effect until it is either rescinded and the responsibility is transferred over to the local jurisdiction or until determined by the CDC Director that he is no longer a public health threat.

Has a federal order of isolation been issued at any other time?

Taking a measure such as issuing an order of isolation is unusual. The last order was issued in 1963.

What was the isolation order that was issued in 1963?

In 1963, the statute was used for quarantine, not isolation, of someone who had been exposed to smallpox. The decision was made to err on the side of caution and implement a federal quarantine requirement for the person until they were outside of their period of incubation.

What row numbers was the patient in?

We are still working with the airlines from the involved countries. On Air France flight 385, the patient was seated somewhere between rows 14 and 57, possibly on row 30. On Czech Air flight 0104, the passenger was seated in 12c.

How many people were on the planes?

The airlines involved in the investigation are large transcontinental airlines and they are generally full of passengers. Air France flight 385 had 433 passengers and 18 crew members and was approximately 13 hours in duration. Approximately 40-50 passengers and the 18 crew members are a priority. The Czech Air flight 0104 had 191 passengers and 9 crew members, and it was longer than 8 hours; around 30 people are a priority for evaluation.

Were public health officials aware that this man was leaving the country?

The local health officials have been involved in the care of this patient with TB from the moment that they were aware of the diagnosis and he was being seen in the clinic. Our understanding, from conversations with the health officials, is that the issue of travel was discussed. The patient was advised that it was not appropriate to travel when you have TB. This situation comes up often when people have TB or other communicable diseases. We have a high success record using voluntary means of information and advice. CDC was not aware that the patient had decided to leave the country.

How many countries are involved?

The number of countries affected by this is large, but the total is not known at this point in time.
