* Indonesian health authorities were conducting contact tracing on Tuesday after detecting the Southeast Asian country's first case of the Omicron variant in the community.

EUROPE

* Spain's infection rate exceeded 1,000 cases per 100,000 people for the first time on Monday, although hospitals were under much less strain than in previous waves of the pandemic.
