A COVID-19 variant that has led to a resurgence in cases in China has been discovered in the United States, the U.S. Centers for Disease Control and Prevention confirmed, but the agency indicated that fewer than 20 cases have been found so far.
A spokesperson for the CDC told The Epoch Times that the agency "is aware of reported cases of COVID-19 NB.1.8.1 in China and is in regular contact with international partners."
Some cases of NB.1.8.1 have been found in the United States, the spokesperson said, adding that it's "fewer than 20 sequences in the U.S. baseline surveillance data to date."
"It has not met the threshold for inclusion in the COVID Data Tracker dashboard. We monitor all SARS-CoV-2 sequences, and if it increases in proportion, it will appear on the Data Tracker dashboard," the spokesperson said.
The NB.1.8.1 strain is a derivative of the XDV COVID-19 lineage, and sub-lineages have been circulating around the world for months, including in mainland China.
Dr. Li Tongzeng, the head of the Infectious Diseases Department at Beijing You’an Hospital, told Chinese state-run media that the resurgence of COVID-19 is expected to peak sometime later in May.
Dr. Jonathan Liu, a professor at the Canadian College of Traditional Chinese Medicine and director of Kang Mei TCM Clinic, said that data published by Chinese health officials in March appear to be inaccurate or misleading, noting that only a few fatalities have been reported.
“With normal epidemic rates, such a low figure is implausible,“ Liu told The Epoch Times this past week.
”Canada, with a sparse population and good sanitation, reported 1,915 COVID deaths from August last year to May this year—over 200 per month.
"How could China, with its dense population, have only seven deaths monthly?”
The WHO also added that “while there are reported increases in cases and hospitalizations” in reporting countries, “there are no reports to suggest that the associated disease severity is higher as compared to other circulating variants.”
The WHO document, dated May 29, did not specifically name any countries impacted by the strain.
“The available evidence on NB.1.8.1 does not suggest additional public health risks relative to the other currently circulating Omicron descendant lineages,” said the WHO, referring to the COVID-19 variant that emerged in late 2021.
Currently approved vaccines are expected to be effective against the variant, the document said.
"Despite a concurrent increase in cases and hospitalizations in some countries where NB.1.8.1 is widespread," WHO added, "current data do not indicate that this variant leads to more severe illness than other variants in circulation."
Health officials in India have also responded to reports that the variant has led to a resurgence in China. In an interview with the PTI news agency, Delhi Health Minister Pankaj Singh said on May 26 that there is no need to panic.
"There is no need to worry. Covid caused by the new variant is similar to a normal viral illness. The patients who have come in so far are experiencing mild symptoms like fever, cough, and cold."
