Bacteria, and different classes of viruses can survive on metal, glass or plastic surfaces for a very long time. For instance SARS-CoV-2 remains active for several days on such surfaces [G. Kampf et al. / Journal of Hospital Infection 104 (2020) 246-251].
The transmission of viruses from surfaces to people is called “smear infection”. While, the role of this route of infection in the spread of COVID-19 has not yet been conclusively determined, it is clear that pathogen-loaded droplets and aerosols are deposited on surfaces. From there they can be absorbed by the hands and further to the respiratory system, since an average adult touches the face about 20-30 times per hour.
PREVOSAN anti-germ protective film can contribute significantly to the prevention of smear infections and thus help to prevent the spread of COVID-19. Based on the independent test results, a significant reduction of pathogen load of surfaces protected by PREVOSAN is achieved within minutes.
Hygiene concepts for public places where many people meet need to consider different aspects: Distance rules, protective masks and regular air exchange can help to reduce the risk of droplet infections.
However, smear infections, which occur even when people don’t meet directly, cannot be prevented by these measures. Until now, surface disinfection has remained the sole measure against surface contamination with viruses. This measure is costly, time-consuming and must be carried out regularly and professionally.
There is a novel and effective alternative: surface hygiene thanks to PREVOSAN.
