Breaking News: New COVID-19 Variant NB.1.8.1 Detected – Urgent Alert from WHO
In a recent development that has triggered global health concerns, the World Health Organization (WHO) has issued an alert for a new variant of the Coronavirus, dubbed NB.1.8.1. This variant, first identified in January 2025, has shown alarming transmissibility, leading to a surge in infections worldwide.
Three New Symptoms to Watch Out For
The WHO has highlighted three new symptoms associated with the NB.1.8.1 variant that require immediate attention:
- Persistent cough
- Fatigue
- Muscle aches
Global Spread and Impact
The variant has been detected in several countries across Asia, Africa, and the United States, including China, Egypt, Maldives, Thailand, Hong Kong, New York, California, and Virginia. The positivity rate has reached 11%, a figure not seen since July 2024, raising concerns among health authorities.
Understanding the Virus’s Evolution
Since its emergence in 2020, SARS-CoV-2 has undergone multiple mutations. The latest subvariant, NB.1.8.1, has rapidly become dominant, replacing earlier variants like Check It and LP.8.1. While the general risk is considered low, its high transmissibility poses a particular threat to vulnerable groups such as older adults and immunocompromised individuals.
Risk and Protection Measures
The WHO emphasizes that existing vaccines continue to offer effective protection, especially in preventing severe illness and deaths. However, the increased transmissibility of NB.1.8.1 necessitates enhanced epidemiological surveillance and immunization campaigns.
