is COVID variant NB.1.8.1 more dangerous?: COVID variant NB.1.8.1 spreading in U.S.: is it more
Hey there! You might’ve seen the headlines about a new COVID-19 variant—NB.1.8.1—making waves overseas and now popping up in the United States. So, what’s the real deal? Should we be concerned, or is it just another name in a long list of variants?
Let’s break it all down in plain, easy-to-digest language.
🦠 What Is NB.1.8.1 and Where Did It Come From?
NB.1.8.1 is a new variant of the SARS-CoV-2 virus—the virus that causes COVID-19. Health authorities first noticed it driving a noticeable uptick in cases in China and Hong Kong. As of now, there’s no indication that it’s more severe than other variants, but it has caught the attention of global health officials due to how fast it’s spreading.
📍 Is NB.1.8.1 in the U.S.?
Yes—but barely. The Centers for Disease Control and Prevention (CDC) confirmed that fewer than 20 cases have been identified in the U.S. so far. These were mostly picked up via the CDC’s airport screening program, which monitors travelers for emerging variants.
📌 Quick Fact: The number of NB.1.8.1 cases is still so small that it’s not yet included in the official CDC COVID Data Tracker dashboard.
🧬 How Is the CDC Monitoring This New Variant?
Even though NB.1.8.1 isn’t widespread in the U.S., the CDC is keeping a close eye on it through gene sequencing and ongoing viral surveillance. If it starts showing up more often in test samples, it’ll be added to the agency’s main tracking tools.
💡 Why it matters: Gene sequencing helps scientists understand how the virus is evolving and whether new variants could pose increased risks.
📉 What’s the Current COVID Situation in the U.S.?
Here’s some good news: According to the CDC’s latest update (as of May 23, 2025), emergency room visits for COVID-19, flu, and RSV are at very low levels across the country. In fact, most states are showing low or very low levels of virus activity in their wastewater testing—a reliable way to monitor community spread.
🗺️ Exception: South Dakota is currently the only state showing higher-than-normal levels of COVID-19 in wastewater data.
😷 Should You Be Worried?
Right now, there’s no need to panic. While NB.1.8.1 is on the radar, experts say there’s no evidence that it causes more severe illness. However, health officials in Hong Kong have advised high-risk individuals to consider wearing masks as a precaution.
👩⚕️ Pro tip: If you’re immunocompromised or caring for someone who is, it’s always wise to stay up to date on vaccines and practice good hygiene.
🧠 Quick Recap (Perfect for Featured Snippets):
What is NB.1.8.1?
NB.1.8.1 is a new COVID-19 variant detected in China and recently found in fewer than 20 U.S. cases.
Is it dangerous?
Currently, there’s no sign that NB.1.8.1 causes more severe illness than other variants.
Should you worry?
Not yet. The CDC is monitoring it, but U.S. cases are too low to raise alarm.
📲 Final Thoughts
As we’ve learned over the past few years, new COVID-19 variants will continue to emerge. But thanks to improved surveillance and global communication, health authorities are much quicker at spotting and assessing these changes.
