Covid-19 Sanitisation Process

What is Coronavirus?

Coronavirus is the overarching name given to a family of viruses which includes many strains, some of which have been responsible for other global crises such as the SARS (Severe Acute Respiratory Syndrome) outbreak in 2002.

Coronaviruses are transmitted between humans and animals, and can cause a range of illness from common colds to more severe respiratory diseases. It is understood the virus is predominantly spread via close contact with an infected person who has the symptoms of the illness such as breathing difficulties, fever, cough or shortness of breath.

This new strain of coronavirus has been named “COVID-19”

While the World Health Organisation (WHO) works with agencies across the world to develop specific medicines, treatments and vaccines, a key focus of efforts has been to try and prevent the spread of the virus through good hygiene practices.

Killing Coronavirus – The Science

Viruses can be active outside the body for hours, even days. Disinfectants, liquids, wipes, gels and creams containing alcohol are all useful at getting rid of them – but they are not quite as good as normal soap.

So why does soap work so well on the Sars-CoV-2, the coronavirus and indeed most viruses?

The short story: because the virus is a self-assembled nanoparticle in which the weakest link is the lipid (fatty) bilayer. Soap dissolves the fat membrane and the virus falls apart like a house of cards and dies – or rather, we should say it becomes inactive as viruses aren’t really alive.

The slightly longer story is that most viruses consist of three key building blocks: ribonucleic acid (RNA), proteins and lipids. A virus-infected cell makes lots of these building blocks, which then spontaneously self-assemble to form the virus. Critically, there are no strong covalent bonds holding these units together, which means you do not necessarily need harsh chemicals to split those units apart.

By Pall Thordarson who is a professor of chemistry at the University of New South Wales in Sydney

When you cough, or especially when you sneeze, tiny droplets from the airways can fly up to 10 metres. The larger ones are thought to be the main coronavirus carriers and they can go at least two metres.

These tiny droplets end on surfaces and often dry out quickly. But the viruses remain active. Human skin is an ideal surface for a virus. It is “organic” and the proteins and fatty acids in the dead cells on the surface interact with the virus.

When you touch, say, a steel surface with a virus particle on it, it will stick to your skin and hence get transferred on to your hands. If you then touch your face, especially your eyes, nostrils or mouth, you can get infected. And it turns out that most people touch their face once every two to five minutes.

Washing the virus off with water alone might work. But water is not good at competing with the strong, glue-like interactions between the skin and the virus. Water isn’t enough.

Soapy water is totally different. Soap contains fat-like substances known as amphiphiles, some of which are structurally very similar to the lipids in the virus membrane. The soap molecules “compete” with the lipids in the virus membrane. This is more or less how soap also removes normal dirt from the skin.

The soap not only loosens the “glue” between the virus and the skin but also the Velcro-like interactions that hold the proteins, lipids and RNA in the virus together.

Alcohol-based products, which pretty much includes all “disinfectant” products, contain a high-percentage alcohol solution (typically 60-80% ethanol) and kill viruses in a similar fashion. But soap is better because you only need a fairly small amount of soapy water, which, with rubbing, covers your entire hand easily.

Whereas you need to literally soak the virus in ethanol for a brief moment, and wipes or rubbing a gel on the hands does not guarantee that you soak every corner of the skin on your hands effectively enough.

So, soap is the best!

Australian Government Guidelines for Disinfecting Covid-19

Many commercial landlords are stipulating that premises must be cleaned after infection, but what is the definition of “cleaning” and what is required to adequately clean?

The Australian Government Department of Health has produced a factsheet on environmental cleaning and disinfection principles for COVID-19, CLICK HERE TO VIEW

Key points to note from this factsheet include:

  • Cleaning is an essential part of disinfection
  • Organic matter can inactivate many disinfectants. Cleaning reduces the soil load, allowing the disinfectant to work
  • Removal of germs such as the virus that causes COVID-19 requires thorough cleaning followed by disinfection
  • The length of time the virus that causes COVID-19 survives on inanimate surfaces will vary depending on factors such as the amount of contaminated body fluid such as respiratory droplets present and environmental temperature and humidity. In general, Coronaviruses are unlikely to survive for long once droplets produced by coughing or sneezing dry out.

The factsheet also states that good practice to routinely clean surfaces as follows:

  • Clean frequently touched surfaces with detergent solution
  • Clean general surfaces and fittings when visibly soiled and immediately after any spillage

Heavily Soiled Organic Removal

Soap Detergent and Hot Water Pressure Clean.

This process is ideal for cleaning large external areas like pathways, play grounds, carparks, tables and seats, smoking areas and other common areas. It is extremely effective in removing soiled organic build up that can harbor viruses and prevents the effectiveness of the disinfecting process. It also breaks down the covalent bonds in the Covid-19 virus.
