The present stance of the CDC rejects the notion that Norovirus can be transmitted through the air. Many microbiologists will tell you otherwise. When you consider the virus is responsible for 200,000 deaths annually, and that the global financial burden is estimated at a staggering $60 billion, it is important that we do all we can to determine all modes of transmission. Plenty of studies, some of which you will see in the links below, suggest that developing methods to treat air and limit transmission can help prevent the spread of this virus, which is thought to infect people five times in their lives. Efforts to understand airborne transmission, developing approaches and technologies to mitigate the spread, are crucial. It costs too many lives and too much money to ignore. Recognizing the threat of airborne transmission – both before and after a potential vaccine is developed – is a critical step toward controlling better the spread of Norovirus.
