This text was initially printed by The Epoch Instances: China CDC Reveals Dominant COVID-19 Variant
Because the worldwide group intently screens the worldwide unfold of Omicron variant NB.1.8.1, China introduced on Could 23 that it’s the major variant spreading within the nation.
On the identical day, a World Well being Group advisory group labeled NB.1.8.1 as a variant beneath monitoring, as a consequence of its rising detection in monitoring efforts across the globe.
The WHO stated they at present contemplate the NB.1.8.1 variant, first detected in January this 12 months, to have a low danger to public well being “at the global level.” It’s not at present deemed a variant of curiosity or concern. The variant is a descendant of JN.1, a sublineage of Omicron.
As of Could 18, 518 sequences of the brand new variant had been submitted by 22 international locations to GISAID, a worldwide influenza and COVID-19 virus genome sequence database, accounting for 10.7 p.c of worldwide sequences in epidemiological week 17 (April 21–27, 2025). This represents a big enhance in detection of the variant from 2.5 p.c in week 14 (March 31–April 6, 2025).
NB.1.8.1’s dominance is especially pronounced in Asia—China’s rapid neighbors.
China revealed a pointy enhance in reported COVID instances, principally pushed by the NB.1.8.1 variant, with residents reporting signs together with extreme burning throat ache, cough, and fever.

Scientists in China, from Peking College, Tsinghua College, and Changping Laboratory, stated the identical in a report printed on Could 1 about NB.1.8.1’s traits, noting its excessive transmissibility and immune evasion. The researchers recommended that NB.1.8.1 may dominate future waves.
Thailand is grappling with a parallel enhance in COVID-19, reporting 33,030 new instances in week 20, doubling from round 16,000 instances the earlier week, Bangkok Publish reported.

As of Could 26, 2025, the WHO dashboard reveals France with the best COVID-19 take a look at positivity price exterior of Asia at 19 p.c.
Mexico has a 15 p.c positivity price, adopted by West Africa’s Burkina Faso at 12 p.c, Ethiopia at 10 p.c, and each Saudi Arabia and Kazakhstan at 7.5 p.c.
India has additionally reported seeing an increase within the NB.1.8.1 variant, in addition to LF.7—additionally a descendant of JN.1. The COVID-19 vaccines deployed since June 2024 have been based mostly on the JN.1 variant.
The WHO stated in its monitoring replace that, “Despite a concurrent increase in cases and hospitalizations in some countries where NB.1.8.1 is widespread, current data do not indicate that this variant leads to more severe illness than other variants in circulation.”
Consultants encourage these feeling unwell to relaxation, keep hydrated, and self-isolate, and use antivirals as wanted. People with comorbidities are really useful to take care of private hygiene and preventive measures to scale back their danger of an infection.
