NB.1.8.1 Covid Variant Spreads Fast, Evades Immunity
A new Covid-19 subvariant, NB.1.8.1, is drawing the attention of global health agencies due to its rapid spread and apparent ability to partially evade immune defences. This Omicron lineage strain is now spreading across multiple regions including India, China, Thailand, and several European countries, prompting increased surveillance by the World Health Organization (WHO). NB.1.8.1 has been categorized as a “variant under monitoring” by WHO, which means it carries genet

Covid Cases Surge in India: New NB.1.8.1 & LF.7 Variants Found
India is witnessing a fresh surge in Covid-19 cases, with health authorities confirming the emergence of two new variants: NB.1.8.1 and LF.7. The total active case count has climbed to 1010 as of May 27, 2025, with Kerala being the worst-hit state. Public health officials are urging calm as symptoms remain mild in most cases, although hospital preparedness has been ramped up across states. The spike in infections is largely being attributed to the new sub-lineages of the JN.1 strain

New COVID Variant NB.1.8.1 Spreads Across U.S. States
A new COVID-19 variant, NB.1.8.1, is now emerging in the United States after becoming dominant in China and causing a significant rise in cases across Asia. U.S. health officials, including the Centers for Disease Control and Prevention (CDC), are monitoring the variant closely as scientists continue to analyze whether NB.1.8.1 poses greater risks in terms of transmission, severity, and resistance to existing vaccines. The variant was initially identified in Asia, particularly in Ch
