A new variant of the COVID-19 virus, NB.1.8.1, has been detected in multiple US locations, raising concerns about its symptoms and potential impact on vaccine access.
The Centers for Disease Control and Prevention (CDC) is aware of reported cases of the variant in China and is monitoring its spread in the US. While hospitalizations abroad have raised questions about the variant’s severity, experts say that so far, it does not lead to more severe illness compared to previous variants.
Symptoms of NB.1.8.1 are broadly similar to those seen in earlier strains of the virus, including respiratory issues like cough and sore throat, fever, and fatigue. However, data suggests it may be more transmissible due to its ability to bind more tightly to human cells.
The Food and Drug Administration (FDA) has announced plans to limit booster vaccine access to some groups, citing a need for major new clinical trials before approving updates for wider use. This decision has sparked concerns about public health impacts, including potential delays in accessing boosters for lower-risk groups.
Experts recommend several strategies for prevention, including good cough and sneezing hygiene, hand washing, staying home if sick, wearing masks, and maintaining social distancing. Authorities in Hong Kong have also begun urging residents to mask in crowded places as cases climb.
