NEW YORK, Nov. 20, 2012 /PRNewswire/ -- A new germ-killing spray product is being introduced at airports across the country for the nearly 25 million Americans who vacation during Thanksgiving weekend, the busiest travel period of the year. With airlines booked to capacity, planes become a "germaphobic" nightmare with planes packed full of families - and germs.

KILLzRx is effective against colds, the flu, sore throats and also help with headaches and nausea while containing key immune system chemicals that fight off attacking viruses. On planes, when air is recirculated throughout the cabin during flight or shut down during long delays on the tarmac, infections can spread like wildfire. Studies have shown that when a plane has its engines off for three hours with no air circulating, a very high percentage of passengers get sick within 2 days. The Federal Aviation Administration issued a warning in 2003 to airlines saying that passengers should be removed from planes within 30 minutes if there's no air circulation. Much of the danger comes from the mouths, noses and hands of passengers sitting nearby. The hot zone for exposure is generally two seats beside, in front of and behind you, according to a study in July in the journal Emerging Infectious Diseases, published by the U.S. Centers for Disease Control and Prevention. Flying at 30,000 feet markedly increases the spread of a disease due to the extremely dry conditions where viruses tend to thrive. Bacteria and germs contaminate tray tables, seat-back pockets stuffed with used tissues, soiled napkins and trash as well as airline's pillows and blankets.
