Man flying is tested positive for Tuberculosis.

The Centers for Disease Control and Prevention says a passenger on a Northwest Airlines flight from Frankfurt to Detroit has been diagnosed with tuberculosis. The passenger was on Flight 51 on March 10th to Detroit Metropolitan Airport. The 17 passengers sitting near the man on the plane have been contacted and advised to be tested for tuberculosis. This is just another PR dilemma for airlines around the world. Security checkpoints can only detect obvious threats. When the threat is microscopic, not much can be done to protect the health of fellow airliners.
What does a PR practitioner do to make a situation like this keep their airline in good light to the public? I have a feeling that the only way to keep our bacterial and viral enemies off of our flights is to make every passenger carry immunological records with them to show proof of being vaccinated for all common diseases. I have no idea how this would go over with the nearly 400 million people that took the air last year. I know I would be pretty upset if I had to renew my shot records just to fly to my destination.
The sad thing is that with the population of people in the world today, steps will soon have to be taken to make sure diseases do not spread throughout the world and kill millions.
There are tons of examples of animals coming and going to other countries and infecting those citizens with disease. Take the rat for example, it carried Black Plague and was transferred from Asia to Western Europe and North Africa killing an estimated 75 million people. Northwest Airlines PR reps will have their hands full if the people in the plane with the sick man all contract TB. Lets hope that no one else contracts the disease and some steps are taken to protect the health of all passengers.
