We will be moving to Optizil for future disinfection of surfaces:
The arrival of SARS-CoV has changed how the world runs today. This is a virus that is highly infective and with severe consequences if you have it.
Three strains, SARS-CoV (first reported in China, 2002), MERS-CoV (first reported in Saudi Arabia, 2012), and SARS-CoV-2 (Wuhan, China, December 2019) pose a significant threat to human life. SARS-CoV-2 Symptoms vary from person to person but typically include fever, breathlessness, and coughing. Contracting SARS-CoV-2 can quickly lead to severe acute respiratory syndrome (COVID-19).
Coronaviruses, as with hepatitis, influenza, herpes, Newcastle disease and smallpox, are enveloped viruses. Enveloped viruses possess an outer coating that is composed of a lipid layer (a fat-like substance that is water-insoluble).
The virus uses the envelope to attach itself to the host cell. Coronaviruses have crown-like projections on their surfaces giving rise to the Latin name ‘Corona’, meaning halo or crown.
With all dental and hospital settings cleaning down after patients has always been important. But because the virus is so infective then we must be sure that the disinfectants were are using can work against SARS-CoV.
We will be moving to Optizil for future disinfection of surfaces.
In a study (Cho et al., 2016) detected the presence of MERS-CoV in viral cultures from four of seven air samples taken from two patients’ rooms, one patient’s bathroom, and one common corridor. MERS-CoV was also detected in the viral cultures for 15 of 68 surface swabs. A second study showed low concentrations of MERS-CoV RNA for environmental swabs taken from bed guardrails and monitors.
Even after cleaning the monitors with 70% alcohol-based disinfectant, RT-PCR showed low concentrations of MERS-CoV RNA remained: the samples only became negative for MERS-CoV after the monitors were wiped with diluted sodium hypochlorite (Song et al., 2015).
The active ingredient in Optizil is Hypochlorous acid (HOCl), which is part of a group of small molecules known as reactive oxygen species (ROS); and is the same chemical produced by the human immune defence system to kill bacteria and fight infection. Neutrophil cells actually release HOCL to inactivate invading pathogens.
Optizil cannot be tested against SARS-CoV2 due to the lack of testable samples, but it has been tested against similar viruses with lipid walls.
OptiZil achieves >5 log viral reductions in less than a minute to non-detectable or safe levels, demonstrating effectiveness as a spray, wipe or bottled solution.
OptiZil can be misted into the environment when people are present with no deleterious effects. It can be sprayed onto a surface and left with no fear of toxic residues. Workers do not need any PPE to handle it.
