An investigation is underway following the emergence of a new COVID-19 virus variant in France, said health authorities in Brittany.
Eight cases of the new COVID-19 virus variant have been detected, though each of the individuals tested negative on their nasal swab tests.
The variant can be confirmed through a blood test or a "deep respiratory" sample, said a news release from the local health authority.
This COVID-19 virus variant may not have increased severity or transmissibility, but an investigation is ongoing to learn more about it and determine how it reacts to COVID-19 vaccines.
These eight cases are part of a cluster of 79 cases reported on March 13.
