We want to know the total number of people infected with COVID-19. To know this, it is necessary to have widespread testing.
When testing is too low we do not have a clear picture of what’s going on.
Testing is crucial to understand the prevalence of the disease, to provide timely treatment to those infected, to understand how the disease evolves, and to ensure that we take measures to stop the disease spreading.
This last point is very important: Testing is crucial to lower the rate of infection. When infected people do not know that they are infected, they might not stay at home – thereby running the risk of infecting others. It’s vital that efforts are increased in this regard.
