Sounds like these doctors want people to use the scanners instead.
Flying is dangerous all around. If not on the soil then in the air. There's no winning.
Right now, what a terrorist would do seems merciful. Disease via gloves, cancer via scanners are long term conditions. Being blown up is quick and painful for a short time. Really there's no escaping discomfort.
There are a lot of diseases that can be transferred via gloves or other vectors..thats why nurses don't use the same gloves on more than I patient. Some doctors are not great on gloves or hand washing in the hospital...will lay charts on patients beds and go into the next room and put the charts again on the beds..I have seen them do that even going into isolation rooms...they think everything they touch is sterile....nosocomal infections are common in most hospitals (illness caught while a patient) tests show that 90% can be eliminated just by good hand washing...
Even clothes can carry bacteria from one person to another in the pat downs. A pair of fresh gloves should be used by TSA agents....could even contract bed bugs....
