COVID-19 

How did we get here?

  • On 31 December 2019, a "pneumonia of unknown cause" is detected in Wuhan, China and reported to the WHO.

  • On 30 January 2020, a Public Health Emergency of International Concern was declared.

  • On 11 February 2020, WHO announced a name for the new coronavirus disease: COVID-19 (and not because it was the 19th strain of the virus, but because it was first detected in 2019).

  • On 20 March 2020, the UK moved from the 'containment' to 'delay' phase of the government's 4-step plan.

  • On 23 March, the four-nations of the UK announced a lockdown.

With no vaccine or drugs available to treat COVID-19, the UK is adopting community-based interventions to help slow the spread of the disease – shops, offices, factories and school closures, remote working for the lucky ones, furloughs for others, and the cancelling of all social gatherings. 

When someone coughs or sneezes, the small liquid droplets from their nose or mouth may contain the virus. If you stand too close, you can breathe in those droplets and catch the virus. It's that simple. Maintaining a distance of at least two metres is designed to reduce those methods of transmission. 

Someone infected with COVID-19 will typically spread it to two or three other people and that's why scientists have given COVID-19 an R-nought (or R0, or RZero) value of R2.5. The aim is to get this value below R1 - it's at that point the disease stops spreading.

 

Four factors go into calculating the R-nought value: Duration, Opportunity, Transmission, Susceptibility.

The social distancing rules that are now part of our daily lives seek to affect the Opportunity value.

By reducing the Opportunity, we ensure the virus has fewer chances to spread to other people simply by:

  • seeing less of them; and

  • maintaining a distance of at least two metres when we're out shopping for essentials, or getting our daily dose of fresh air.

What we find incredible is that every single one of us can actively lower the R-nought value, protect the most vulnerable in our communities, and play a significant role in getting the country back to 'Business As Usual'.

For social distancing to be successful, everyone needs to actively reduce the rate and opportunity of person-to-person contact to reduce the risk of spreading the virus.

NorthStar Security Consultancy Ltd will be back trading under the 'new normal' as soon as restrictions are lifted, but in the meantime we will continue to support our clients from the comfort of our own home.

 

We hope you can Stay Home, Protect the NHS ... and ultimately Save Lives. We also hope you 'Stay Safe'.
