"Test, Test, Test," said the DG of WHO (Director-General of the World Health Organization) at the beginning of the Pandemic outbreak.

There was and continues to be a very important reason for that - 

  • The virus is highly contagious so one person can infect many others
  • Many patients are asymptomatic or mildly symptomatic

In this situation, the only way to contain the spread of the disease is to diagnose patients early - before they infect others. The only way to do that is by aggressive testing, diagnosing, contact tracing, and then isolating the contacts. 

In this video, I will focus on what are the two types of tests for Covid-19. I will also discuss what happens in case there is a 'False Positive' or 'False Negative' report.
