Effective national leadership and trust in government appear to be prerequisites for countries to achieve widespread digital contact tracing.
Contact tracers are among the many unsung heroes of our public health efforts to control the coronavirus, in Victoria and beyond. But they need help.
Despite disappointing download numbers and almost zero success in tracing COVID-19 infections, Australia is persisting with the COVIDSafe app, while the rest of the world embraces the 'Gapple' model.
A rapid launch of tracing and testing combined with localised lockdowns aims to keep the virus under control until a vaccine is found.
The reason the UK contact-tracing apps failed? It fell foul of privacy rules decided in California.
Police departments have suggested using contact tracing approaches to track protesters, raising concerns about data and privacy.
Contact tracing for sexual health has been taking place in England for many years. Why was this workforce ignored in the coronavirus response?
South Korea's mass surveillance to curb the coronavirus pandemic uses technologies and techniques that are grounded in anti-LGBTQ discrimination.
The UK locked down too late and has been in catch-up mode ever since. But with contact tracing, it can turn things around.
For contact tracing to be effective, the UK needs quick, accurate testing and lots of tracing capacity – and also for the public to be on board.
Smartphone apps and wearable devices can tell when workers have been within six feet of each other, promising to help curb the coronavirus. But they're not all the same when it comes to privacy.
New Zealand has “eliminated” COVID-19 “for now”, Prime Minister Jacinda Ardern has declared. Two key epidemiologists who worked on NZ’s elimination strategy explain the news, and the challenges ahead.
Epidemiological data suggests that 80% of COVID-19 cases can be traced to just 20% of those infected with SARS-CoV-2.
If coronavirus is still circulating, why are we safer now that social distancing measures have been relaxed? A public health expert explains.
There's now a 95% chance COVID-19 has been eliminated in NZ, according to our modelling. But as NZ prepares to remove limits on large gatherings, it increases the risk of a very large new outbreak.
It is generally assumed that this disease-control technique goes back to the 1840s, but it's actually much older.
Since the state's first coronavirus case surfaced, trained case investigators have traced the contacts of every person who tested positive. Here's what else South Carolina got right.
Humans can identify asymptomatic cases, build trust and assauge fears. Apps cannot.
COVIDSafe uses Bluetooth radio waves. These can only measure how physically close two people are, but not if those people are in the same room, or even in different cars passing each other.
Test, trace, maintain social distance, and keep travel bans and quarantines in place. These measures will help Australia keep the coronavirus in check as we gradually emerge from lockdown hibernation.
