World concerned about Omicron: Analysis Updated: 2021-12-06 17:04:30 KST

The Omicron variant is causing much concern around the world.
First reported in South Africa, now the variant reportedly has been found in more than 40 countries, including here in South Korea.
For more, we have Professor Peter Nyasulu from Stellenbosch University, joining us live from South Africa.
Professor Nyasulu, welcome to the program.

What do we know about Omicron so far, about its transmissibility, severity, ability to evade detection and ability to evade vaccines, compared to Delta?

Other than Omicron, there's a number of other COVID-19 variants.
Why do new variants emerge… that have different characteristics?
And how can we prevent possible future variants?

Some countries are imposing travel bans. Will those measures be effective?

The WHO's emergencies director Mike Ryan says currently the focus should be on distributing vaccines more widely and says there's no evidence that we will need tailor-made vaccines against Omicron.
What's your view?

The WHO says Covid cases jumped more than 300 percent in South Africa in just seven days at the end of November.
Why is that? What restrictions are in place in South Africa and what are some challenges?

Professor Peter Nyasulu. Thank you for your insights, we appreciate it.
