New Covid Variant NB.1.8.1 Identified in Europe
The emerging variant has drawn attention from international health authorities due to its rapid spread.
The new Covid-19 variant, identified as NB.1.8.1, is being detected in an increasing number of countries across Europe, attracting the interest of international health organizations due to its swift transmission rate.
According to data from the global GISAID repository, the first cases of the NB.1.8.1 variant were recorded at the end of April, primarily among patients arriving from China, France, Japan, the Netherlands, Spain, South Korea, Taiwan, and Thailand.
Additionally, the variant was detected in the United States through an airport testing program coordinated by the Centers for Disease Control and Prevention (CDC) as early as late March, with cases reported in states including California, Hawaii, New York, Ohio, Rhode Island, Virginia, and Washington.
Although NB.1.8.1 has not yet been listed in the CDC's tracking system for Covid variants due to the relatively low incidence of cases, researchers emphasize the importance of monitoring its spread.
Current knowledge indicates that this variant does not lead to more severe illness compared to other Omicron subvariants.
However, its genetic modifications may enable it to infect cells more effectively, potentially resulting in higher transmissibility.
Observations thus far suggest that the symptoms associated with the new variant do not significantly differ from those of earlier variants, with common complaints including sore throat, fever, cough, and fatigue.
