A new variant has new symptoms.
FACT CHECKED BY Emilia Paluszek

The rise of the worldwide BA.2 subvariant of Omicron has health experts on high alert. As of now, they're not sure if the new iteration of COVID-19 will cause a new surge in the U.S. Some reports indicate that BA.2 is causing some slightly different symptoms. They're important to be aware of so you can get tested, isolate, and call your doctor ASAP for advice if you develop them. Read on to find out more—and to ensure your health and the health of others, don't miss these Sure Signs You've Already Had COVID.


Dizziness and Fatigue

Some different early symptoms have been reported with the BA.2 subvariant, said Washington State health official Francisco Velazquez recently. Namely: Dizziness and fatigue. Unfortunately, previous Omicron infection doesn't seem to be protective against contracting BA.2, he said. But the COVID vaccines are still highly protective against severe illness or death.


Stomach Pain

Last month, scientists with the ZOE COVID Symptom Study said there had been a "sharp increase" in reports of stomach pain. "Gastrointestinal (GI) problems — such as diarrhea, stomach pains, feeling sick and losing your appetite or skipping meals — can all be symptoms of COVID-19," they said, while noting those symptoms might also be attributable to seasonal stomach flu.


Symptoms Seem to Depend on Vaccination Status

BA.2 seems to present differently depending on whether you've been vaccinated or not. "If you're vaccinated, it seems to be more milder symptoms, and I'm very hopeful that we're not going to have an additional strain on the healthcare system," medical researcher Dr. Jasmine Plummer told ABC 7 Los Angeles on Tuesday.  


BA.2 Symptoms Not That Different Overall

Otherwise, Omicron and BA.2 symptoms don't markedly differ from the Delta variant, the COVID Symptom Study indicates. The five most common symptoms are the same: Runny nose, headache, fatigue, sneezing and sore throat. People have also frequently reported loss of appetite and brain fog, but those were also common with previous variants.

On PBS NewsHour last week, Dr. Anthony Fauci, the nation's top infectious-disease expert, said that BA.2 has one "very important difference" from Omicron and several similarities."It is more transmissible," he said. However, "it doesn't appear to be any more severe, and it doesn't seem to evade immune responses either induced by the vaccine or by prior infection."
