If I get COVID-19, is there a way to tell if I used Omicron or BA.2. Some say that certain symptoms may be related to subvariants, but others are unknown at this time.

Incoming Whitehouse COVID-19 Response Coordinator Dr. Ashish Jar talks about the new Omicron subvariant BA.2 and whether the United States will see the surge that Europe and Asia are experiencing.

The symptoms of BA.2 are similar to those seen in many COVID infections, including:

  • Fever or chills

  • Shortness of breath or shortness of breath
  • Malaise
  • Muscle and body pain
  • headache
  • New loss of taste and smell

“When we are sick and our bodies are taking care of infections, we can get something like fever,” Lee said. “Especially if you have a fever, and if you sweat a lot, you are losing a lot of water.”

Another doctor pointed out that Omicron caused more upper respiratory tract symptoms, but said it was too early to tell in BA.2.

“For now, I’m not sure if I know a specific feature that is different between BA.2 and BA.1. That is, for BA.1, it’s not primarily an upper respiratory tract infection, but an upper respiratory tract infection. It was known to be a lower respiratory tract infection that can cause pneumonia and more serious complications, “said Gregory Moon, a doctor of infections and COVID-19 vaccine coordinator at the Cook County Health Department. The doctor says.

For some people, the coronavirus causes mild or moderate symptoms and cures in a few weeks. For others, it may not cause any symptoms. For some, the virus can cause more serious illnesses, including pneumonia and death.
