A disinfectant spray made from non-toxic colloidal silver is making its way into subway and train stations in many parts of the world. The spray, which leaves a coating of nano-silver-titanium dioxide, has already been used in the subways of Hong Kong. These rail systems handle about 2.5 million riders each day, making them a veritable hot bed of disease transmission.
The spray has been certified as effective against molds, bacteria and viruses, including H1N1, the much feared virus that causes Bird Flu. Spraying common surfaces, such as handrails, ticket-dispensing machines, elevators, grab straps and poles can kill many harmful disease spreading organisms.
The most common means by which disease is spread is by touching disease organisms, then passing them on to other parts of the body by subsequently contacting the mouth, nose or eyes. Many public metro systems are currently attempting to develop measures to discourage disease spread among commuters. Shared technology between transportation enterprises worldwide can indicate best practices for all public transportation networks.
