An official from the World Health Organization told a press conference Tuesday that another COVID-19 variant has infected a dozen people in France and has been on the agency’s radar, according to a report.

Bloomberg reported that the “IHU” variant, which was nicknamed by researchers at the Marseille-based Mediterranee Infection University Hospital Institute (IHU), has infected individuals in the southern Alps region in the country. Abdi Mahamud, a WHO incident manager, told researchers in Geneva that it’s too soon to “speculate on virological, epidemiological or clinical features” of the variant that was identified in November—at about the same time as omicron.

The IHU variant, or B.1.640.2, has 46 mutations but Bloomberg pointed out that the strain has not become a major threat since its discovery. The first patient identified with the variant returned to France from visiting Cameroon, according to a study that was not peer-reviewed and released in December.
