A new variant of coronavirus
is prompting renewed concern regarding the pandemic. The World Health
Organization (WHO) named the new variant “Omicron.” Omicron is labeled a
“variant of concern,” the agency’s serious category for tracking. Such a
designation is reserved for dangerous variants that may be more transmissible
or virulent or could decrease the effectiveness of vaccines or treatments.
This article features Omicron information from the Centers for Disease Control and Prevention (CDC).
On Nov. 24, 2021, a new coronavirus
variant was reported to the WHO. This new variant was first detected in
Botswana and South Africa.
On Dec. 1, 2021, the first
confirmed U.S. case of Omicron was identified. The CDC continues to collaborate
with global public health and industry partners to learn about Omicron and
monitor its course. At the time of publication, experts don’t yet know how
easily it spreads, the severity of illness it causes, or how well available
vaccines and medications work against it.
Despite
the increased attention of Omicron, Delta remains the main variant circulating
in the United States.
The
CDC shared the following information about the infection and spread of Omicron.
How easily does Omicron spread?
The Omicron variant likely
will spread more easily than the original coronavirus strain, but how easily
Omicron spreads compared to Delta remains unknown. The CDC expects that anyone
with an Omicron infection can spread the virus to others, even if they are
vaccinated or don’t have symptoms.
Will Omicron cause more severe illness?
More data is needed to know
if Omicron infections, especially reinfections and breakthrough infections in
fully vaccinated people, cause more severe illness or death than infection with
other variants.
Will vaccines work against Omicron?
Current vaccines are expected
to protect against severe illness, hospitalizations and deaths due to infection
with the Omicron variant. However, breakthrough infections in fully vaccinated
people are likely to occur. With other variants, like Delta, vaccines have
remained effective at preventing severe illness, hospitalizations and death.
The recent emergence of Omicron further emphasizes the importance of COVID-19 vaccination and boosters.
Will treatments work against Omicron?
Scientists are working to
determine how well existing treatments for COVID-19 work. Based on the changed genetic makeup of Omicron,
some treatments are likely to remain effective while others may be less
effective.
There are several
tools available today in the United States to fight the Omicron variant. According to the CDC, the following tools can help reduce
the spread of Omicron in our country:
- · Vaccines remain the best public health measure to protect
people from COVID-19, slow transmission and reduce the likelihood of new
variants emerging. The CDC recommends everyone
5 years of age and older protect themselves from COVID-19 by getting fully
vaccinated.
- ·
Masks offer protection against all variants of COVID-19. Regardless of vaccination status, the CDC recommends wearing
a mask in public indoor settings in areas of substantial or high community
transmission.
- · Tests can tell you if you are currently infected with
COVID-19. Visit your state, tribal, local or territorial health department’s website
to look for the latest local information on testing.
While we learn more about the
risk of Omicron, it’s essential to use all
tools available to protect yourself and others.
CDC experts are working to
gather data and virus samples that can be studied to answer important questions
about the Omicron variant. Scientific experiments have already started, and the
CDC will provide updates as soon as possible.
