Protecting against Covid-19
What is the Coronavirus?
A new strain of Coronavirus (COVID-19) emerged in 2020 and is causing illnesses globally and is different from other coronaviruses. COVID-19 seems to spread more easily than flu and causes more serious illnesses in some people. It can also take longer before people show symptoms and people can be contagious for longer.
How is it transmitted?
Transmission routes for COVID-19, include:
- The air by coughing and sneezing
- Close, personal contact, such as touching or shaking hands
- Touching surfaces or objects contaminated with virus particles, then touching your mouth, nose or eyes before washing your hands
Typically, a person develops symptoms 5 days after being infected, but symptoms can appear as early as 2 days after infection or as late as 14 days after infection, and the time range can vary.
It’s possible for people to spread the virus for about 2 days before experiencing signs or symptoms and remain contagious for at least 10 days after signs or symptoms first appeared. If someone is asymptomatic or their symptoms go away, it’s possible to remain contagious for at least 10 days after testing positive for COVID-19.
What levels of contamination can happen?
Minimal Infectious Dose
The key to effective disinfection is to understand how contagious bacteria and viruses can be. Rates can vary depending on the strain, however as few as 10 viral particles or bacteria can trigger infection in an individual.
Effective kill rate for Surfaces
Companies and standards use log reductions to prove efficacy of products against a variety of bacteria, fungi and viruses. It is vital that the log reductions reduce the contaminated area to below 10 particles to ensure protection. While levels of bacteria and viruses vary by location, regularity of cleaning and surface type, sneezing and coughing releases hundreds of thousands of particles resulting in contaminated areas that can carry millions of microbes. A product can kill to:
- 3-log reducing 10,000 particles to 10 but anything above that level leaves a potential for infection
- 4-log reducing 100,000 particles to 10
- 5-log reducing 1,000,000 particles to 10
- 6-log reducing 10,000,000 particles to 10
Typically, a minimum of 5 log is required to ensure that contaminated areas can be disinfected. Speed of effectiveness and conditions are less important than the kill rate itself as these can be dealt with on site.
Nothing is more important than effective kill.
How to reduce the risk of transmission using biotechnology?
- Damages outer membranes, causing leakage of cell contents
- Attacks other cell structures, proteins and DNA
- Prevents protein synthesis
- Arrests energy production by the cell
This provides high log kill rates across a quick time frame in clean and dirty conditions. The added benefits of using our biotech solution is that it is up to 30,000 times less toxic to the environment when compared to traditional disinfectants and offers a carbon neutral solution, saving up to 5kg CO2e per litre of concentrate.
