NEW CARONA WARENT HA BEEN LEAKED FROM SOUTH AFRICA New variants of the virus are expected to occur. Taking steps to reduce the spread of infection, including getting a COVID-19 vaccine, are the best way to slow the emergence of new variants.
Vaccines reduce your risk of severe illness, hospitalization, and death from COVID-19.
COVID-19 booster doses are recommended for adults ages 18 and older. Teens 16–17 years old who received Pfizer-BioNTech COVID-19 vaccines can get a booster dose if they are at least 6 months post their initial Pfizer-BioNTech vaccination series.Vaccines
While vaccines reduce your risk of severe illness, hospitalization, and death from COVID-19, we don’t yet know how effective they will be against new variants that may arise, including Omicron.
Symptoms
All previous variants cause similar COVID-19 symptoms.
Some variants, such as the Alpha and Delta variants, may cause more severe illness and death.
Masks
Wearing a mask is an effective way to reduce the spread of earlier forms of the virus, the Delta variant and other known variants.
People who are not fully vaccinated should take steps to protect themselves, including wearing a mask indoors in public at all levels of community transmission.
People who are fully vaccinated should wear a mask indoors in areas of substantial or high transmission.
Wearing a mask is very important if you or someone in your household
Has a weakened immune system
Has an underlying medical condition

Vaccine: Breakthrough infections in people who are fully vaccinated are expected, but vaccines are effective at preventing severe illness, hospitalizations, and death. Early evidence suggests that fully vaccinated people who become infected with the Delta variant can spread the virus to others. All FDA-approved or authorized vaccines are effective against severe illness, hospitalization, and deat
Treatments: Nearly all variants circulating in the United States respond to treatment with FDA-authorized monoclonal antibody treatments.h.tss.a
CDC is working with state and local public health officials to monitor the spread of Omicron. As of December 20, 2021, Omicron has been detected in most states and territories and is rapidly increasing the proportion of COVID-19 cases it is causing.
Omicron Spread
CDC is monitoring the current surge of COVID-19 cases. Learn more about the Omicron variant and its expected impact on hospitalizations.
What We Know about Omicron
CDC has been collaborating with global public health and industry partners to learn about Omicron, as we continue to monitor its course. We don’t yet know how easily it spreads, the severity of illness it causes, or how well available vaccines and medications work against it.
Spread
The Omicron variant likely will spread more easily than the original SARS-CoV-2 virus and how easily Omicron spreads compared to Delta remains unknown. CDC expects that anyone with Omicron infection can spread the virus to others, even if they are vaccinated or don’t have symptoms.
Severe Illness
More data are needed to know if Omicron infections, and especially reinfections and breakthrough infections in people who are fully vaccinated, cause more severe illness or death than infection with other variants.
