New crown

You're referring to the COVID-19 pandemic!

The "new crown" is a colloquial term used in some parts of the world, particularly in Asia, to refer to the SARS-CoV-2 virus that causes COVID-19. The term is thought to have originated from the crown-like shape of the virus's spike proteins.

The COVID-19 pandemic, caused by the SARS-CoV-2 virus, was first detected in Wuhan, China in December 2019. It has since spread rapidly around the world, infecting millions of people and causing widespread illness, death, and economic disruption.

The term "new crown" is often used in combination with other terms, such as "new crown pneumonia" or "new crown disease", to refer specifically to the COVID-19 pandemic.

It's worth noting that the term "new crown" is not an official medical term, and it's not widely used in scientific or medical literature. However, it has become a common term in popular culture and everyday conversation in many parts of the world.
