Japan confirms 8 more cases of Omicron variant infection

All eight entered Japan from late November to early this month, according to a government official, Kyodo reports.

Deputy Chief Cabinet Secretary Seiji Kihara said two of the eight people are close contacts of the first case of the variant confirmed in Japan -- a person who arrived from Namibia late last month -- while declining to give further details.

«We will thoroughly implement appropriate anti-virus measures by monitoring the situation through strengthened border control and genome analyses,» Kihara told a regular press conference.

Japan announced its first case of the new variant on Nov. 30.

The World Health Organization has warned the Omicron variant, which has been confirmed in many other parts of the world, could be more transmissible than previous strains of the virus or be able to evade immunity provided by vaccines.
