A new coronavirus infection (COVID-19) mutation (B.1.1.529), 'Omicron', has spread in South Africa, causing an emergency around the world.

Major countries are hastily restricting the entry of travelers from South Africa and neighboring regions.

This is because, in order to prevent a pandemic caused by the influx of delta mutations from India last summer, it is essential to quickly block entry from regions where new mutations have been reported.

Accordingly, South Korea is also expected to impose travel and entry restrictions on African countries. Criticism of the South Korean government's failure to control entry when the coronavirus began to spread in Wuhan, China, in early 2020, continues.

Earlier, on November 26, the World Health Organization (WHO) classified a new coronavirus mutation (B.1.1.529) found in South Africa as a 'variant of concern' and named it the 15th letter of the Greek alphabet. It was designated as 'o Omicron'.

Currently, there are five variants of concern: alpha, beta, gamma, delta, and omicron.

Omicron mutations are mainly found in South Africa, and related confirmed cases have also been reported in Botswana and Hong Kong. Omicron mutations were found to have a whopping 32 genetic mutations in the spike protein that affects the propagation power. Delta has 16 mutations. Because of this, scientists are concerned that the new mutation may have as high a propagation power as the existing delta mutation.

In particular, omicron mutations appear to possess both high contagiousness and avoidance of vaccine immune responses. Because of this, it is predicted that existing corona vaccines will not be effective.

On November 25, starting with the UK and Israel, 27 EU member states and the US, as well as major Asian and Pacific countries, began to block travelers from South Africa and neighboring regions. Asia-Pacific countries are also taking measures to block this trend.
