Does the Omicron COVID-19 variant cause more severe disease?

Omicron infection generally causes less severe disease than infection with prior variants. Preliminary data suggest that Omicron may cause more mild disease, although some people may still have severe disease, need hospitalization, and could die from the infection with this variant.

Is the COVID-19 vaccine effective against the Omicron variant?

Omicron in the United States

CDC is working with state and local public health officials to monitor the spread of Omicron. As of December 20, 2021, Omicron had been detected in most states and territories and continues to be the dominant variant in the United States.

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 are still learning about how easily it spreads, the severity of illness it causes, and how well available vaccines and medications work against it.

We have the Tools to Fight Omicron

Getting vaccinated and staying up to date with COVID-19 vaccines is the best way to protect yourself and others against the Omicron variant.

What CDC is Doing to Learn about Omicron

CDC scientists are working with partners to gather data and virus samples that can be studied to answer important questions about the Omicron variant. Scientific experiments are ongoing. CDC will provide updates as new information becomes available.

Emergence of Omicron

CDC has been using genomic surveillance throughout the course of the pandemic to track COVID-19 variants, and inform public health practice.

COVID-19 symptoms from Omicron could last for a week or two

As with previous variants, Omicron has proven to be different in how it affects people in terms of the symptoms that it causes.

One study found that Omicron symptoms could last anywhere from a few days to a week

Some of the earliest information on the duration of the virus comes from a study that looked at one of the first recorded Omicron superspreader events at a holiday party in Norway on Nov. 30.

What are the symptoms of Omicron?

Using the most recent data from London, where Omicron prevalence is higher than other regions of the UK, ZOE data scientists analyzed symptom data from positive cases recorded in the ZOE COVID Study and compared with data from early October when Delta was dominant.

Does Omicron cause more hospitalizations and deaths than Delta?

Even as cases rise, the proportion of hospitalizations and deaths seems to be dropping in most countries where Omicron has been detected. The same is true of our analysis of London, although there is often a delay between catching COVID and being hospitalized with complications, so this might change in the coming weeks.

If the symptoms are mild, why should I worry about Omicron?

News about Omicron has caused alarm across the globe with good reason. We still have a lot to learn about Omicron and it’s not yet clear what kind of pressure it will put on global health systems.

What can I do to protect myself and others from Omicron?

If you live in an area experiencing high rates of infection, consider staying home and reducing social contact

People Should Still Be Vigilant

Even if Omicron can feel like "just a cold” to those fully vaccinated, it is much more transmissible. This means people are at a higher risk of reinfection. Gulick says that even for those who are vaccinated, a reinfection rate may be as high as 30%.

What About Long COVID?

We also still learning about long COVID. Babcock says Omicron hasn’t been around long enough yet to have a good sense of whether it is different from earlier variants when it comes to the likelihood of lingering symptoms.

How to Protect Yourself

As Gulick points out, getting booster shots is crucial. He also says that on top of vaccines, it’s important people wear masks, practice social distancing and avoid indoor crowds whenever possible. Testing, if you suspect you have COVID, can help curb spread and protect others. And if you are sick, or suspect you could be sick, stay home.

More transmissible

Danish researchers have found that BA.2 is about 30% more transmissible than BA.1. Denmark was one of the first countries where BA.2 became dominant, and public health authorities around the world have paid close attention to the situation there to gather insight on what the subvariant might mean for the future course of the pandemic.

Reinfection possible, but appears rare

Danish scientists confirmed Tuesday that the BA.2 subvariant can reinfect people who previously had its omicron predecessor, BA.1, though the risk of catching the virus again appears low.

CDC relaxes Covid guidance allowing most people to ditch masks if hospitalizations remain low

Vaccines

The original omicron BA.1 strain demonstrated a substantial ability to escape antibodies induced by the vaccines, leading to many breakthrough infections during the recent surge. Danish scientists found that BA.2 is better at evading vaccine protections than BA.1, according to a study published last month.
