The Ricardo Jorge National Health Institute said Monday that one of those who tested positive at the Lisbon-based Belenenses soccer club had recently traveled to South Africa, where the Omicron variant was first identified.
The others, however, had not traveled to South Africa, indicating that this may be one of the very first cases of local transmission of the virus outside of southern Africa.
Those who have been in contact with the positive cases have been ordered to isolate, regardless of their vaccination status or their exposure to possible contagion, and will be regularly tested for COVID-19, the institute said.
