A new COVID variant, HV.1, is now dominant. These are its most common symptoms
What is HV.1, the new COVID variant?
HV.1 is part of the omicron family. “You can almost think of HV.1 as a grandchild of omicron,” says Schaffner. HV.1 is a sublineage of omicron XBB.1.9.2 and a direct descendent of EG.5, according to the CDC's SARS-CoV-2 lineage tree.
“The COVID family of viruses likes to mutate. We’ve all learned that by now," says Schaffner. While HV.1 is mutated, it's still very close to the existing omicron subvariants, Schaffner explains.
For the most part, scientists are not concerned about new variants like HV.1, which look very similar to strains we've already seen before, NBC News reported.
However, there are a few highly mutated strains which have set off alarm bells. These include BA.2.86 or Pirola, which has an extra 36 mutations that differentiate it from XBB.1.5., and a newer variant called JN.1, which has one more mutation than Pirola.
Fortunately, neither BA.2.86 nor JN.1 are common in the U.S. right now, according to the CDC — JN.1 is so rare that it makes up fewer than 0.1% of SARS-CoV-2 cases.
As for HV.1, it rapidly gained steam after it was first detected this past summer. In late July, HV.1 accounted for just 0.5% of COVID-19 cases in the U.S., CDC data show. By Sept. 30, HV.1 made up 12.5% of cases, and by November, it was the dominant strain.
What are HV.1 symptoms?
The symptoms caused by infection with HV.1 are similar to those caused by recent variants, says Schaffner, which include:

What are HV.1 symptoms?
The symptoms caused by infection with HV.1 are similar to those caused by recent variants, says Schaffner, which include:
- Sore throat
- Congestion or stuffiness
- Runny nose
- Cough
- Fatigue
- Headache
- Muscle aches
- Fever or chills
