Is the Delta COVID-19 variant more severe than the Omicron?

Severity: Delta caused more severe disease than other variants in people who weren't vaccinated. Early studies from Scotland and Canada, both cited by the CDC, suggested Delta was more likely to result in hospitalization in the unvaccinated.

Is there a difference in spread between the Omicron and Delta COVID-19 variant?

The Omicron variant spreads more easily than earlier variants of the virus that cause COVID-19, including the Delta variant. CDC expects that anyone with Omicron infection, regardless of vaccination status or whether or not they have symptoms, can spread the virus to others.

Does the COVID-19 Omicron variant spreads more easily?

New variants of the virus are expected to occur. Slowing the spread of the virus, by protecting yourself and others, can help slow the emergence of new variants. The Omicron variant causes more infections and spreads faster than the original SARS-CoV-2 strain of the virus that causes COVID-19.

Should I be worried about getting the COVID-19 Omicron variant?

While some have suggested that most people will eventually get the coronavirus, you should do your best to avoid infection with Omicron—there is no justification for deliberately getting infected so you have what you think will be a mild illness that will provide you with more immunity going forward, the doctors say.

What are the differences between the delta and mu variants of COVID-19?

The highly infectious delta variant is twice as contagious as previous variants. It was first identified in India in December of 2020. Mu was first detected in January 2021 in Colombia. Mutations of SARS-CoV-2, the virus that causes COVID-19, have been emerging since the pandemic began.

Sept. 2, 2021 -- The World Health Organization is tracking a new COVID-19 variant called Mu, which could be able to evade the immunity provided by vaccines and prior infections.

The variant, also known as B. 1.621, was first identified in Colombia in January.

Is the Delta variant more contagious than the original strain of COVID-19?

People infected with the Delta variant have roughly 1,000 times more copies of the virus in their respiratory tract than those infected with the original strain of COVID-19.

Is Omicron COVID-19 variant more contagious for children?

Omicron has proven to be the most contagious COVID-19 variant of the pandemic so far. The main difference with Omicron is the sheer number of kids getting sick at the same time. Without vaccines and boosters for younger children, it feels like an agonizing wait for many families.

Which Brazilian variant of COVID-19 is more transmissible?

A recent study conducted by investigators from Brazil, the United Kingdom and the University of Copenhagen has found that the COVID-19 variant P. 1, which originated in Brazil, is more transmissible than the original virus and is able to evade immunity. Results from the study were published in the journal Science.
