Very interesting article o contact tracing where even the Uk gets a mention but we are lagging far behind the Asian nations.
Victoria’s contact tracing system has been under scrutiny in recent weeks, while New South Wales has been held up as a gold standard.
But how does Australia measure up on a global scale?
According to one expert, we still have a way to go.
Professor Tony Blakely, from the Melbourne School Of Population And Global Health, says Australia is still in the process of scaling up its contact tracing capacity.
We’re well ahead of the UK, where Professor Blakely says contact tracers have been swamped by cases.
But Australia is not yet up to speed with some East Asian countries, where infrastructure is more advanced, largely because of previous infectious diseases outbreaks like SARS and swine flu.
Did anyone else read about the mum who went for a Covid test but because she had to pick up her kids from school she abandoned the queue so never actually took the test…a few days later she got a notification that her test was positive…makes you wonder how accurate the figures are.
I think there are only two ways this will end.
The first is if the majority of people catch the virus and become resistant, thereby breaking the chain of infection.
And secondly, clearing areas by preventing the mixing of infected people with none infected people until there is no infection left in that area. This could only be done by preventing travel in or out of a quarantined area and gradually expanding the border until the whole country is clear of the virus.
But travel between countries would have to be prevented otherwise the whole situation would re-emerge. It only takes one infected person to sneak through.
In theory, if fourteen days is enough to quell the virus (the usual amount of time we have been quarantining) then total lockdown for just 14 days would be all that’s required, and we need to pull up the drawbridge!
But with air traffic continuing (I live close to an airport and it appears ‘Business as usual’) this could be too difficult to sustain unless some hard decisions are made by governments. Not likely…
One big problem with the fist proposition (immunity or resistance) is ther we have already seen cases of documented reinfection.
Worse still is that the second infection has been more severe!
If that was the case Zaphod, then a vaccine wouldn’t work because a vaccine works on the same principal of building resistance through infection. Some people do not respond to a vaccine or build antibodies through infection.
Around one in four people hospitalised with COVID-19 suffer heart damage, according to new research published in the Journal of the American College of Cardiology.
