LAKE FOREST, Calif., Feb. 22, 2013 /PRNewswire/ -- Innovative BioDefense Inc., the creators of the Zylast™ line of antimicrobial products, announced today that independent testing has demonstrated that its Zylast products are 100 times more effective against Norovirus than alcohol-based hand sanitizers on the market. Norovirus, also often called the "stomach flu" or the "cruise ship virus," is one of the major causes of a digestive-tract epidemic that is currently gripping the country. Its major symptoms include explosive diarrhea and projectile vomiting. It is especially dangerous in close quarters, often striking hospitals, schools, nursing homes, and cruise ships with outbreaks. A new variant of Norovirus called the Sydney 2012 variant is the cause of much of the problem. Research at one of the foremost independent laboratories in the United States, BioScience Laboratories, demonstrated that the Zylast products destroyed 99.97% of the Norovirus on contact. Unlike other personal sanitization products on the market based on alcohol, Zylast has proven it can effectively kill the Norovirus immediately, as well as offering persistence for six hours. Zylast products have also shown to be effective against Rotavirus (the most common cause of diarrhea in children), Rhinovirus (the cause of the common cold), and the H1N1 flu virus. Since Norovirus' main means of transmission is contaminated hands or workspaces, washing or wiping down with Zylast is an effective preventative treatment, said Beth McNichol, Ph.D., a specialist in infectious diseases based in Maryland. "Zylast provides a simple, effective and persistent method to sterilize your hands and your environment, and I recommend it wholeheartedly," Dr. McNichol said. "While an alcohol-based sanitizer can be effective against some bacteria, these products really offer no more protection against viruses than simply washing your hands. To prevent contamination against Norovirus, you need the broad-spectrum protection of a product like Zylast."
