Is new Covid variant Mu more dangerous?

World Health Organisation (WHO) has said it was monitoring the spread of another variant of interest — Mu. It was first identified in Colombia in January and has since infected people in South America and Europe. Mu’s possible resistance to vaccines is what makes it risky for the global population. Now, the WHO has said that more research was needed to better understand its behaviour.

With the latest addition, there are five variants of interest for the WHO — Eta, Iota, Kappa, Lambda, and Mu.

Mutations in viruses are not new. All viruses, including SARS-CoV-2, undergo change over time. Most of these changes are inconsequential, but some can alter properties to make these viruses more virulent or escape the treatment or vaccines.
