How is the COVID-19 virus detected using real time RT-PCR?

As the virus that causes the COVID-19 disease spreads across the world, the IAEA, in partnership with the Food and Agriculture Organization of the United Nations (FAO), is offering its support and expertise to help countries use real-time reverse transcription-polymerase chain reaction (real-time RT-PCR), one of the most accurate laboratory methods for detecting, tracking, and studying the coronavirus.

But what is real-time RT-PCR? How does it work? And what does it have to do with nuclear technology?
