Nasal Decolonization


Mounting evidence suggests many viruses gain their foothold in humans by infecting certain nasal cells. Infected cells in the nose are also a likely source of viral shedding and spread.


When a person is infected with a virus, they typically do not get sick right away. During what’s known as an incubation period, the virus replicates inside the body. Once it has replicated enough to reach a critical mass (or viral load), that person may start to show symptoms.


Even if they don’t  – or are recovering and feeling better – there might be a sufficient viral load in their system that they are at risk of spreading it to others, from droplets and/or aerosolized particles produced when they cough, sneeze, sing, or even talk.


Nasal decolonization with topical antiseptics is a common infection control practice in hospitals. One application of Certainty SmartShield has been shown to help prevent viral replication in the nose for hours.
