An Australian scientist has used a simple graphic of Swiss cheese to help stop the spread of COVID-19 in countries where the virus is out of control.
Virologist Ian Mackay, from Brisbane, created a simple diagram using the well known dairy product to demonstrate how the virus can spread through ‘holes’.
‘Each slice of cheese has holes, but each action can prevent the virus escaping through these holes,’ Dr Mackay told The Courier Mail.
Dr Mackay and his colleagues at the University of Queensland collaborated on the infographic, which is being used by international health officials including the Centers for Disease Control and Prevention in the US.

‘We are happy that it is of use in other countries, where they can tweak it to suit their own environment.’
Dr Mackay said the ‘simple yet complex’ graphic has been given a lot of attention on Twitter.

It recommends physically distancing and staying home if you’re sick, limiting your time in crowded areas, testing and tracing quickly and ventilating indoor areas.
Dr Mackay said the objective of the graphic is to encourage social distancing, mask-wearing, washing hands and coughing into your arm.
‘If you are not wearing a mask or wearing an ineffective mask then the virus will escape through a hole but then there is another backup,’ he said.
Meanwhile, hopes of international travel resuming are growing with the success of coronavirus vaccine trials.
