The US Centers for Disease Control and Prevention (CDC) has detected multiple cases of the new COVID-19 variant "NB.1.8.1", which has been linked to a surge in cases in China. A CDC spokesperson confirmed the findings to Fox News Digital, but said there had been very few instances of the strain being included in the agency's "Covid Tracker."
"To date, there have been fewer than 20 sequences of 'NB.1.8.1' in the U.S. surveillance database, so it has not met the threshold for inclusion in the COVID Data Tracker panel," a CDC spokesperson told Fox News. "We monitor all sequences of SARS-CoV-2, and if it grows proportionately, it will appear on the Data Tracker panel."
The cases were reportedly discovered through the CDC's airport screening program, according to CBS News.
While the CDC has detected the new variant in the US, the agency also reported on May 23 that emergency room visits for influenza, COVID and RSV are currently "very low". In its two-week forecasts for COVID and flu, the CDC said it expects the number of emergency room visits to likely remain at the current low.
A CDC map showing COVID-19 cases detected through wastewater (sewage) testing shows that most states are seeing low or very low levels of the virus. The only state experiencing a high level of viral activity, according to CDC data, is South Dakota.
The COVID-19 variant NB.1.8.1 has been linked to a high number of cases in China and Hong Kong.
Earlier this month, Hong Kong authorities issued a statement urging the public, especially high-risk individuals, to wear surgical masks. However, the statement also noted that there is no evidence that NB.1.8.1 is more serious than other COVID-19 variants.
