Is there a chance that I’ll get severely sick if I do get omicron?

As opposed to delta, it appears that the danger is reduced with delta

When it comes to SARS-CoV-2, the greatest hazard is that a minor disease will develop into a potentially life-threatening one. Despite the fact that this is still a possibility with omicron, the risk looks to be lesser than it was with delta.

A study published online on Jan. 2 provides some of the first persuasive data from the United States indicating the risk of ending up in the hospital is reduced with the omicron variation when compared with the delta variant. The study was conducted in the United Kingdom.

Case Western Reserve University researchers examined health records from more than half a million people infected with SARS-CoV-2 across the country, including 14,000 people who may have been infected with the omicron variant between December 15 and December 24, after the variant became dominant in the virus.

“During this time period, there is still some delta floating around in the society. You, on the other hand, are increasingly gravitating toward the omicron version “Davis, who was a contributor to the study, explains.

They next checked to see if there was any difference between persons who had contracted the virus at the end of the delta wave and those who had contracted it during the early stages of the omicron wave, and they found none. “The difference was significant,” says Rong Xu, a data scientist at Case Western Reserve University who was the study’s principal investigator. To see the difference, we didn’t have to use any complex statistical analysis.

After controlling for other factors, Xu and her colleagues discovered that the risk of needing emergency care dropped from about 15 percent during the delta surge to 5 percent during the early omicron surge (a reduction of about 70%), and the risk of being hospitalized dropped from 4 percent to 2 percent during the early omicron surge (or by 50 percent ).

If a person does wind up in the hospital, the likelihood of that person being admitted to the intensive care unit (ICU) or being placed on a ventilator has fallen significantly since the peak of the delta spike. In particular, the risk of being admitted to the intensive care unit (ICU) decreased from 0.8 percent to 0.4 percent (a 50 percent reduction), and the possibility of being placed on a ventilator decreased from 0.4 percent to 0.1 percent.

Furthermore, scientists in South Africa and the United Kingdom have observed a lower risk with omicron, which is consistent with their findings.

According to Xu and her team’s estimates, around 60% of the participants in their study were immunized. As a result, while some of this lower risk may be due to vaccination, the evidence as a whole suggests that the omicron version is associated with a lower risk of hospitalization when compared to the delta form.

Children under the age of five, who are not eligible for vaccination, as well as children aged 5 to 15, who may have been vaccinated but have not been given a booster, were shown to have a similar reduction in risk, according to Xu and her research team.

According to Xu, this consistency shows that the reduction in severity is attributable in part to something intrinsic in omicron itself, rather than simply to changes in immunization status.

According to Xu, “there is something that is fundamentally different between the omicron and delta.” To summarize, this decrease in risk does not necessarily imply that omicron will be mild for everyone. People who are at high risk for severe sickness, such as the elderly or those who have underlying health difficulties, nonetheless have a high likelihood of being admitted to the hospital, which is a substantial risk factor. To give an example, if you’re over the age of 65, your risk of being hospitalized with COVID-19 is still 5 percent with the omicron form, which implies that 1 in every 20 persons who become infected in this age range will wind up in a medical facility. (By contrast, the rate of infection with the original version of the virus was 1 in 10.)

“The risk is not zero,” adds Xu’s colleague Davis, while discussing the omicron particle. “A large number of people will continue to be hospitalized to the intensive care unit, and some people will continue to require mechanical breathing.”

That is why, according to her, everyone should be immunized and given a booster shot. As with previous versions, getting vaccinated against omicron significantly reduces your risk of contracting a serious sickness. According to a study published last week by the United Kingdom’s Department of Health, three doses of the omicron vaccine reduce the chance of hospitalization due to the disease by approximately 80 percent when compared to not being vaccinated at all.

So, how horrible is it going to be if you end up in the hospital?

The fact that omicron is milder than delta is not detracting from the fact that many hospitals are overcrowded due to the sheer volume of patients who are becoming sick with the virus.

And doctors are noticing a significant difference between their patients who end up in the ER or who are admitted: many are not battling to breathe or experiencing dangerously low oxygen levels.

According to Mount Sinai’s Carr, these two characteristics were “a hallmark of the first illness and of delta, and were not nearly as prominent in omicron,” respectively.

Prior to the discovery of COVID-19, it was assumed that a severe case would wreak havoc on the lungs, sometimes resulting in pneumonia and uncontrolled inflammation. Nonetheless, because of this apparent change in the condition — the fact that a serious infection in the lungs does not appear to be as common — fewer patients are need to use supplementary oxygen or be intubated.

“They’re not out of breath, and their lungs appear to be in good condition,” adds Yale’s Roberts. These data are also consistent with laboratory studies, which has found that omicron does not replicate in lung tissue as efficiently as delta.

Many of the patients who are admitted to the hospital have an underlying medical condition, or they are elderly and hence more susceptible to a viral infection than younger individuals. “What we’re seeing is that there’s something that really pushes these folks over the line,” Roberts says. Examples include the development of complications from an existing condition such as diabetes or heart failure, as a result of an omicron infection.

However, according to Roberts, it is still uncommon for people who have been vaccinated and boosted to become gravely ill as a result of omicron. Unvaccinated patients account for approximately 80% of the total number of patients at Yale New Haven Hospital. And, of those who have been vaccinated, almost all have not received a booster dose since their initial vaccination.

While it is encouraging to learn that omicron is less harmful to the lungs, ProHEALTH’s Griffin reports that this is not the case for all of his patients. And, according to him, an omicron infection in an unprotected person can feel like the same harsh sickness as a polio infection.

According to Griffin, “when we have a patient who is younger, when we have a patient who has been vaccinated, when we have a patient who has recently recovered from delta, we’re more likely to observe very minor disease with omicron.” “However, among persons who are new to the virus and have no prior protection, it’s difficult to tell if the illness is milder.”
