12 months agoUS
The COVID-19 landscape continues to evolve with the emergence of new variants. Here’s a breakdown of what you need to know about the Nimbus (NB.1.8.1) and Stratus (XFG) variants, including their spread, symptoms, and potential impact.
Key Insights
•
Nimbus (NB.1.8.1) and Stratus (XFG) are rapidly spreading:: Both variants are competing for dominance globally.
•
Nimbus may cause a "razor blade" sensation in the throat:: Some reports suggest a distinctive sore throat symptom.
•
Stratus is good at evading the immune system:: It has mutations that help it evade antibodies.
•
Existing COVID-19 vaccines are still likely to be effective:: Protection against severe illness, hospitalization, and death remains.
In-Depth Analysis
#### Background
COVID-19 has not disappeared and continues to evolve, with the World Health Organization (WHO) monitoring several variants. Nimbus and Stratus are two such variants gaining attention.
#### Nimbus (NB.1.8.1)
•
Spread:: Identified in January 2025, it has quickly spread across Asia and other regions.
•
Symptoms:: May cause a "razor blade" sensation in the throat and gastrointestinal symptoms.
•
Infectivity:: Binds strongly to the ACE2 receptor, facilitating efficient spread.
#### Stratus (XFG)
