The new Omicron sub-variant will soon become the predominant variant of COVID-19 in the United States. According to the Centers for Disease Control and Prevention (CDC), 42.6% of COVID-19 cases in the country are currently responsible for BA.2.12.1. This is a larger increase than the 7.5% case that was responsible in early April.
This is a subvariant that public health officials will monitor and try to learn more about. “Additional assessments are currently underway to understand the impact of BA.2.12.1 on vaccine efficacy,” CDC Director Rochelle Valenski said at a news briefing late last month. “But most importantly, we believe that those who have been vaccinated, and especially those who have been vaccinated, will continue to have strong protection against severe disease even before BA.2.12.1.”
The rise of BA.2.12.1 comes shortly after the end of most mandates for masks across the country, including on public transport. However, you may have questions about what this option is and how you should be concerned. Here’s what you need to know.
What is BA.2.12.1?
BA.2.12.1 explains that this is a BA.2 sub-variant of the Omicron variant, i.e., the “secret Omicron”, William Schaffner, MD, Infectious Diseases Specialist and Professor at Vanderbilt University School of Medicine. “You might think this is Omicron’s son or daughter,” he says. “They’re really very similar.”
But BA.2.12.1 paid a lot of attention to how contagious it was. “This is the most contagious form of SARS-CoV-2 described,” said Amesh A., a senior scientist at the Johns Hopkins Health Center. Adalja. (SARS-CoV-2, if you don’t know it well, it’s the virus that makes COVID-19.)
BA.2.12.1 has certain mutations in its spik protein, which makes it more infectious, Dr. Schaffner says.
Why is BA.2.12.1 growing in the US?
According to Thomas Rousseau, a professor at the University of Buffalo in New York and chief infectious disease specialist, there are several different reasons for the rise in BA.2.12.1 levels in the United States. One is how contagious it is, he says.
“The original Omicron – BA.1 – was more contagious than previous versions,” the doctor said. Explains in Russian. “BA.2 is considered to be approximately 30% more infectious than BA.1 and BA.2.12.1 is considered to be 30% more infectious than BA.2.”
The rapid spread of BA.2.12.1 also coincides with mitigated restrictions almost everywhere, Dr. Russian says. “Both of them contributed to its spread,” he says.
There is a simple fact that BA.2.12.1 is eliminating other options for hurting people, Dr. Adalja says. “It is being raised by simple Darwinist principles – it is spreading more efficiently and surpassing other SARS-CoV-2 breeds,” he says.
What are the symptoms BA.2.12.1?
Physicians and public health workers are still learning more about BA.2.12.1, but for now, Dr. According to Schaffner, it is believed that COVID-19 causes the same symptoms as other types. Among them by the CDC:
- fever or chills
- Difficulty breathing or breathing
- to be tired
- Muscle or body aches
- Head pain
- New loss of taste or smell
- sore throat
- Turning or runny nose
- nausea or vomiting
“It doesn’t seem to be more serious than other types of COVID-19,” the doctor said. Schaffner says. “And most importantly, according to laboratory studies, our vaccines provide very good coverage against this subvarian, but you need to take a third dose.”
How worried I should be BA.2.12.1?
Dr. Adalja said the growth of BA.2.12.1 was “fully expected” and added that “the virus will continue to develop as more and more contagious”. Hence, even higher infectious options are expected afterwards.
This option should be a concern for everyone, but Dr. Rousseau said the people who were most concerned were those who were considered to be at high risk for serious complications for COVID-19.
“If you’re fit, get a boost,” he said. Russian says. “If you think you are dangerous, be careful. Few people now wear masks. When there is a heavy burden of disease in the community, you should consider wearing a mask to protect yourself. ”
