Many parts of the world are seeing a resurgence of COVID-19.
And what's more concerning is the new Omicron variant first reported in South Africa.
A number of countries have imposed travel restrictions on South Africa and neighboring countries.
For more, we have our go-to medical expert, Dr. Alice Tan joining us live.
Dr. Tan, thanks for joining us.
There was an announcement by the WHO last week about this new variant.
But we still know little about its transmissibility, or whether current vaccines work against it. What are we learning so far?
It's still unclear whether current vaccines are effective against Omicron but the authorities still recommend that people get boosters.
What are your thoughts?
Some experts say that while Omicron could be more infectious its symptoms could be less severe.
What's your take?
There's been infections of the Omicron variant already reported in Europe, Canada and Japan.
What should other countries, including South Korea, do to prevent further spread?
In South Korea, cases are increasing every day, there are more critically ill patients, and hospital beds are running short.
And the country has put on hold its schedule for returning to normal.
Will this help curb the virus which seems a bit out of control now?
That was Dr. Alice Tan from MizMedi Women's Hospital. Thank you for your insights.
