BA.2.12.1 variant COVID-19 accounts for about 37% of new coronavirus cases nationwide, according to the latest data from the Centers for Disease Control and Prevention.
The growth of BA.2.12.1 and other variants is to be expected, say health experts.
“SARS-CoV-2, the virus that causes COVID-19, is constantly changing and accumulating mutations in its genetic code over time. New variants of SARS-CoV-2 are expected to continue to appear. “Some variants will appear and disappear, while others will appear and continue to spread and can replace previous variants,” the CDC said.
BA.2.12.1 is a descendant of BA.2 virus, a subvariant of the omicron strain COVID. BA.2.12.1 has the ability to be more easily transmitted than its predecessors, and experts said it could become the dominant strain of COVID-19 within a few weeks.

What are the symptoms of BA.2.12.1?
Like the previous variant BA.2, BA.2.12.1 is most often manifested by upper respiratory tract symptoms similar to influenza symptoms. Original symptoms of COVID-19 include:
- Fever or chills
- Shortness of breath or difficulty breathing
- Muscle or body pain
- Loss of taste or smell
- Sore throat
- Nasal congestion or runny nose
- Nausea or vomiting
The omicron variant most commonly occurs with sneezing, coughing, and sore throat. Additional symptoms from BA.2 include fatigue and dizziness.
.The best way to reduce the effects of COVID and its variants is vaccination, experts say.
“Penetrating infections are expected in people who have been vaccinated, but updating recommended vaccines is effective in preventing serious illness, hospitalization and death. The emergence of the Omicron variant further emphasizes the importance of vaccination and grooming, ”said the CDC.
