To control the COVID-19 pandemic through random testing would require about 6.5 million test a day. Using group testing and machine learning could get that number down to fewer than 40,000 day.

Recent cases remind us that although children and teens are considered less likely than adults to catch and spread COVID-19, everyone with symptoms should get a test — including children and teens.

The prospects of elimination remain elusive but even with the current Victoria outbreak, Australia is maintaining a high number of tests per thousand people.

There are some very good reasons why some people decline coronavirus testing, which we need to address before jumping to conclusions.
Saliva testing is less sensitive than a nasal swab. But in the midst of a public health crisis, in some cases a test with slightly reduced sensitivity may be better than no test at all.
As compulsory testing and more restrictive quarantine rules are being considered, it is critical these measures are properly communicated and used with restraint.
Australia is performing better than many other countries with comparable populations and geographies, a new COVID-19 data visualisation reveals.

Countries across the globe responded differently to the pandemic, and results show a difference in effectiveness as well.
The SARS-CoV-2 coronavirus is currently detected using invasive nasal swabs. But the virus is also present in saliva, potentially paving the way for cheaper, safer tests that people could do at home.
As we start to test people without symptoms for COVID-19, the likelihood of generating false positive tests goes up. Here's why that's a problem.

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.
The Life Care Center in Kirkland, Washington, had the first known COVID-19 outbreak in a U.S. nursing home. In Massachusetts, one-third of nursing homes now have more than 30 COVID-19 cases.

The government doesn't know how many people have died of COVID-19, in part because it didn't require nursing homes to report cases to the CDC. In some states, over half of deaths are in nursing homes.
The government plans to monitor sewage for the SARS-CoV-2 coronavirus. And while this holds promise to tracking future local outbreaks, there are also some sticky ethical questions to consider.
As New Zealand prepares to ease its lockdown from April 28, new COVID-19 clusters are likely to emerge – but a combination of testing and contact tracing should be able to stamp out major outbreaks.

Don't just tell us how many new cases of COVID-19 have been confirmed, tell us how many people you tested as well. That helps us to know if things are getting better or worse.
Developed nations like Spain struggled to provide enough hospital beds for coronavirus patients, so what are poorer nations to do?
COVID-19 is creating overwhelming needs for intensive care and testing facilities. An Australian team is developing purpose-built units that can be shipped and erected quickly, easily and cheaply.
