Top doctor urges 'healthy paranoia' to combat virus
Other states should follow Western Australia's "healthy paranoia" in tackling the pandemic, according to a top doctor.
From today, WA has tightened its border further by only allowing transport and freight workers from virus-stricken Victoria to enter.
Industry chiefs have been told to source interstate workers for mining, agriculture and other sectors from outside Victoria.

Andrew Miller, President of the WA Australian Medical Association, told Today the state's stringent measures are a lesson for the entire country.
"The important thing is to not let the virus in at this stage. The best way we can support the rest of the country is by staying healthy, supporting the economy and really being ultra paranoid. If you like, a healthy paranoia about letting this thing into the community in the first place.

Dr Miller says with WA's population concentrated in a few cities and towns, residents are vulnerable to infection.
"We've seen in Victoria that once you get to 40 or 50 cases a day, for more than a week, it becomes very, very hard the trace and track this thing.
"If you get the numbers you see in Victoria, you are going to see how quickly this little fire can start to spread into your border communities."

Dr Miller also said it was time to consider new measures to track infections such as the public wearing of masks and the government tracking of mobile phones.
"Maybe the population will accept in return for being able to go to a restaurant ... (to say) 'I will allow the authorities to know in retrospect where I was at the time'."
