新型コロナウイルス感染症（COVID-19） | 2025年 | NB.1.8.1 変異株が世界的に増加
5 years after the pandemic began where does the COVID 19 stand today the answer might surprise you recent data shows infection rates are climbing again globally but the story is more complex than the headlines suggest a new variant named NB.1.8.1 has been identified as a contributing factor to rising infection rates in various regions first detected in January 2025 this variant has rapidly separated over 22 plus countries accounting for approximately 10 to 11% of sequenced global cases by mid May or early June we have currently many different variants globally spreading and of those the dominant ones are two NB.1.8.1 and LP.8.1 the NB1 variant is the newest and fastest rising variant now accounting for 11% of global cases this variant has been driving surges in China US India and many other countries with experts predicting it could fuel summer cases also whereas the LP.8.1 previously the dominant variant globally though it circulation has been declining in recent months as NB.1.8.1 gains ground this variant shows increased transmissibility but generally causes milder symptoms in vaccinated individuals and we have less lethal variants like XFC and XEC as the virus continues to adapt the NB.1.8.1 is the new threat nowadays first detected in early 2025 the NB.1.8.1 8.1 is a part of Omicron family and has recently been classified by the World Health Organization as a variant under monitoring this label signals its growing separate and potential impact on public health if we see genetically it carries several mutations in the spike protein the part of the virus that helps it to latch onto our cells these changes could make it more infectious or help it partially evade immune system key spike proteins mutations includes T22N F59s G184S A435S V445H and T478I by midMay 2025 the NB.1.8.1 accounted for over 10 to 11% of all sequenced cases worldwide it has been detected in more than 22 countries including United States United Kingdom China Thailand India and many other countries in India NB.1.8.1 is among the variants contributing to a gradual rise in cases especially in the states like Kerala Maharashtra and Delhi while the number of active cases remains relatively low just over 4,000 as of early June the trend is being closely watched fortunately the symptoms remain mild in most cases particularly among vaccinated individuals common signs include fever fatigue sore throat and mild respiratory symptoms similar to what we have seen with earlier Omicron strains and for this COVID 19 disease we have separate playlist that includes top vaccines omicron variant structure of SARS COV2 how the virus invades our immune system and evades and many other videos if you want to watch these videos these videos have been linked in the description i hope you like the video if you like it give it a thumbs up do consider supporting my work on Patreon or YouTube and make sure to subscribe channel thanks

As the COVID-19 virus continues to evolve, a new variant called NB.1.8.1 has emerged and is now under global surveillance. Detected first in early 2025, NB.1.8.1 is part of the Omicron family and has recently been classified by the World Health Organization (WHO) as a Variant Under Monitoring (VUM) — a sign of its increasing spread and potential public health impact.
🔍 In this video, we explain:
✅ When and where NB.1.8.1 was first detected
✅ How it fits within the Omicron lineage
✅ What makes it different from previous variants
✅ Symptoms and transmissibility trends
✅ WHO’s response and global monitoring
✅ What you should do to stay safe
📌 This video is based on the latest data as of June 2025 and presents a clear and science-backed breakdown of NB.1.8.1 for the general public.
