A total of 40% of cases of infection with the delta variant in Norway can probably be linked to one trip this spring, according to the National Institute of Public Health (FHI).
Gene analyses from the FHI shed light on how the fourth virus wave started, the newspaper Aftenposten writes.
747 of the 1,870 delta samples that the FHI has analyzed, 40%, can be traced back to this case of imported infection, according to the report.
It is not known whether a lone traveler or a travel group brought the delta variant to Norway, but the analysis shows that the infection came to Norway in April. Then it spread throughout Viken and Oslo.
Researchers at the FHI can not pinpoint which country the traveler(s) came from, but they stated that the variant is similar to viruses from Central and South Asia.
