How does the delta variant compare to the Omicron variant?

The study looked at data from 69,279 patients—52,297 with the Omicron variant, 16,982 with the Delta variant—between November 30, 2021, and January 1, 2022. When comparing the two variants, the study found that Omicron cases resulted in 53% less risk of hospitalization, 74% less risk of ICU admission, and 91% less risk of death.

What are the benefits of the Omicron variant?

When comparing the two variants, the study found that Omicron cases resulted in 53% less risk of hospitalization, 74% less risk of ICU admission, and 91% less risk of death. The study also found that none of the patients with Omicron required mechanical ventilation.

What is Omicron and what are the symptoms?

Omicron is not making people as ill as previous variants, but the sheer volume of people testing positive is still forcing huge numbers to isolate. What are the symptoms of Omicron? Omicron appears to be more like a cold for some people, with common reported symptoms including a sore throat, runny nose and a headache.

What do we know about the Omicron 62 BA variant?

The Omicron 62 BA.1 variant was originally discovered in November 2021 and quickly assigned by the World 63 Health Organization as a variant of concern due to its alarming number of mutations (Centers for 64 Disease Control and Prevention, 2022a; Khandia et al., 2022).

What is the difference between the Delta and Omicron variants?

More than six studies have found that Omicron is milder than the Delta variant and others. While previous variants have scarred the lungs and caused breathing difficulties in humans, several studies with mice and hamsters have found that the variant caused much milder symptoms.

Does Omicron variant affect hospitalization and death rates?

Compared with patients who had the delta variant, omicron patients had a 53% reduced risk of hospitalization, a 74% reduced risk of ICU admission and a 91% reduced risk of death. The study has not yet been peer-reviewed.

What are the different variants of Omicrons Spike?

Some mutations in omicrons spike protein are similar to ones found in the delta variant, according to South Africas Department of Health, as well as mutations found in the alpha, gamma and beta variants -- all classified as variants of concern by the World Health Organization.

What do we know about Delta variant?

For example, the spike protein of the Delta variant has more efficient cell-cell fusion kinetics as compared to the original Wuhan strain. All variants will be monitored by scientists and may be classified as variants being monitored, variants of interest, variants of concern and variants of high consequence.

The spike in cases has been driven by the Omicron sub-variants BA.4 and BA.5, which have ousted BA.2 as the dominant strains in the UK. Here is what you need to know about them. What are the symptoms of BA.4 and BA.5? There is currently no evidence to suggest that BA.4 and BA.5 cause different symptoms to previous Covid strains.

What is Omicron and is it dangerous?

What are the symptoms of the Omicron variant?

Omicron symptoms can look like flu and cold symptoms and cause headache, sore throat and runny nose. Omicron appears to cause milder symptoms than previous variants—especially in fully vaccinated people. People need to get their booster shots for the most protection. If you’re unsure if you have a cold or COVID, get tested as soon as possible.

What does an omicron infection look like?

Because of Omicrons shortened incubation period, those who are infected will begin to show symptoms sooner, if theyre symptomatic. Most of the time, particularly because Omicron tends to be less severe, a case may look a lot like the common cold, or even allergies .

How long do Omicron symptoms last?

As far as how long these Omicron symptoms last, research shows that people have acute symptoms for about six to seven days—about two days shorter than Deltas eight to nine days of acute illness. That said, length of symptoms varies greatly depending on the person, their vaccination status, the severity of disease, and any risk factors.

Is a sore throat an omicron symptom?

A sore throat is an early sign of the virus, so can be a good way to begin isolating and testing. This Omicron symptom is also common across all age-groups, with the throat infection being relatively mild. However, a more painful sore throat lasting longer than five days may be more than an Omicron symptom.
