What is mass testing? Thanks for asking!

The benefit of screening for diseases is to enable early diagnosis when a person is asymptomatic. That’s the case for a large proportion of those infected with COVID-19, which is why mass testing is being championed as a solution to slow the spread of the disease. With lockdown measures being eased in many places, there’s a risk of the coronavirus circulating more freely again. To combat this, governments are ramping up their screening capacities, in order to test more widely.

But is the mass testing working in other countries?

Several countries have seemingly handled the health crisis better than others due to mass testing. South Korea has carried out more tests than any other country since the start of the pandemic. At 10,000 per day, the country was able to react quickly to new waves of infection. Meanwhile in Europe, Germany was quick to react to the danger of the virus spreading. From the end of January, they began widespread testing of those returning from countries where the virus had already struck. On the other hand, certain countries have been criticised for not reacting quickly enough in this area, even after a global pandemic had been declared. The UK government set itself a target of 100,000 tests per day, which it’s so far struggling to meet. And in the United States, researchers believe that 20 million tests would be required every day, in order to safely reopen the economy.
