The dominant coronaviruses strain around the world is the omicron subvariant BA.2. Since November, health officials have known about it, but they are still learning about how it works and how sick people are likely to get.

With that in mind, here is what the newest subvariant means for you and your family, as well as the signs you should keep an eye out for.

BA.2 often presents similarly to a bad cold

The symptoms and severity of the original omicron variant are similar to what we are seeing now.

A cough, fatigue, and loss of taste or smell are some of the symptoms of a mild BA.2 infection. A skin rash, headaches, and a nose that isn't normal are some of the common signs and symptoms. It's similar to what people experience with a cold.

Dr. Lighter noted that with the original omicron strain, she saw more patients with upper respiratory symptoms, such as a cough and a sore throat, than with previous strains. The original omicron strain seems to target the upper respiratory tract more than BA.2 does, but a lot of that is just anecdotal at this point.

It is possible to get sick from BA.2. Emergency warning signs include persistent pain, chest pressure, and difficulty breathing.

The real-world evidence shows that BA.2 and BA.1 cause less severe illness. The vaccine reduces the odds of getting sick. More than half of the US population is now fully vaccine free.

Health officials are cautiously optimistic. Dr. Anthony Fauci, the nation's top infectious disease specialist, has predicted that hospitalizations aren't likely to go up because of the new omicron subvariant. The U.K. recently experienced a surge in cases, but not a surge in severe illness.

But remember: Even ‘mild’ cases can feel pretty bad.

When doctors use the term "mild" to describe illness, they are basically saying it wasn't serious enough that the person needed to be hospitalized. Symptoms of BA.2 could make you incapable of doing anything for days or weeks. You could feel terrible. There is a chance that even a mild case of COVID-19 can lead to long COVID.

The big question is whether or not you are able to recuperate at home.

Even if you feel crummy, you still have what most doctors would consider amild case.

If you experience any symptoms, you should test — even if you’ve already had COVID.

If you have any symptoms, it is important to take a COVID-19 test. Even if you have been boosted and have recovered from COVID-19, that is still true. It is not likely that you would get BA.1 and BA.2 in a short period of time.

You should test if you have symptoms. It is all about assessing the risk.

With BA.2 circulating, it is more important than ever to stay up to date on vaccines.

One of the reasons experts are hopeful that BA.2 won't cause a huge spike in hospitalizations and deaths is because most places around the country have dropped mask mandates.

Recommendations have changed so it is important to stay on top of them. The Food and Drug Administration authorized a second booster for adults 50 and older this week. Some doctors and researchers think that kids as young as 5 may need a booster. Make sure you work with your provider, get up to date on your shots, and pay attention to community transmission levels.

As long as people follow the current guidance, that's the best thing they can do.

The experts are still learning. As scientists discover more about the virus, the information in this story can change. The Centers for Disease Control and Prevention has the most up to date recommendations.
