The Omicron variant is less severe than the Delta variant of COVID-19, revealed a study conducted in California which was backed by data confirmed by the United States Centers for Disease Control and Prevention. CDC Director Rochelle Walensky highlighted that even though the Omicron variant is less severe, however, it is more transmissible. According to the CDC data, the risk of hospitalization caused by the virus was reduced to half for people who have been infected with Omicron, in comparison to the Delta variant.

According to the CDC data, Omicron has a mortality rate 91% lower than that of Delta. The study also states that the duration of hospital stay was 3.4 days shorter for hospitalized cases with Omicron variant infections, in comparison to patients hospitalized with Delta variant infections, reflecting a 69.6% reduction in length of stay in hospitals. Around 53% reduction in risk of symptomatic hospitalisations was witnessed in the Omicron variant in comparison with the Delta variant.

What Did President Joe Biden Say About The New Variants

On January 4, 2022, President Joe Biden addressed the nation in regards to the recent surge in Covid-19 cases and the variants thought to be behind the rise.

“We have the tools to protect people from severe illness due to Omicron – if people choose to use the tools,” Biden said.

“Theres a lot of reason to be hopeful in , but for Gods sake, please take advantage of whats available.”

The President encouraged Americans to continue to get vaccinated, receive boosters, wear masks in public, and follow the rules of social distancing.

“You can still get Covid, but its highly unlikely that youll become seriously ill,” Biden said, in reference to those who are fully vaccinated.

“If youre vaccinated and boosted, you are highly protected. Be concerned about Omicron, but dont be alarmed,” he continued.

“And if youre unvaccinated, you have some reasons to be alarmed. Youll experience severe illness in many cases.”

Are Delta Symptoms Different

The Delta variant produces different symptoms, according to the ZOE study. The ZOE Symptom Study has been collecting information through an app, where people have been logging their symptoms since March 2020. Over four million people from around the world have been taking part its the biggest ongoing study about coronavirus. Information reported to the app shows that people are having different symptoms, either instead of, or in addition to, the main symptoms above. The new symptoms include:

  • headache
  • sore throat

Omicron Covid Variant Symptoms

COVID symptoms linked to the omicron variant have been described as “extremely mild” by doctors in South Africa who first raised the alarm over the new strain.

Most of the new cases in South Africa have been among people in their 20s and 30s, and doctors note that age group generally has milder symptoms of COVID-19 in any case.

They warn though that older people infected by the new variant could have more severe symptoms.

Omicron Variant: Why The CDC Now Says You Should Get a COVID Booster Shot

We’ve seen a sharp increase in cases for the past 10 days. So far they have mostly been very mild cases, with patients having flu-like symptoms: dry coughs, fever, night sweats, a lot of body pains,” said Dr. Unben Pillay, a general practitioner in Gauteng province where 81% of the new cases have been reported.

Dr. Angelique Coetzee, chair of the South African Medical Association, told the BBC on Sunday that she started to see patients around Nov.18 presenting with “unusual symptoms” that differed slightly to those associated with the delta variant, which is the most virulent strain of the virus to date and globally dominant.

“It actually started with a male patient who’s around the age of 33 … and he said to me that he’s just extremely tired for the past few days and he’s got these body aches and pains with a bit of a headache,” she told the BBC.

Why Is The Delta Variant Dangerous


The COVID-19 Delta variant is dangerous because its a more contagious mutation of the original strain of COVID-19 virus that has caused a spike in hospitalizations around the nation. At this time, there is still some debate as to whether the variant is associated with worse clinical outcomes. Specifically, it is not known if more people are getting sick because of a combination of high case numbers among vulnerable populations, or low vaccination rates. There also could be impact on patient care and outcomes related to increased stress on hospital systems.

As more and more data are collected, however, it appears that people infected with the COVID-19 delta variant experience different symptoms than those experienced with other strains. With that being said, theres no indication that the associated symptoms are more severe in nature.

Common symptoms of those infected with the COVID-19 delta variant include fever, headache, sore throat, and runny nose. Unlike the original strain of COVID-19, cough and loss of smell are not common symptoms.

Other reports link the variant to more serious symptoms, including hearing impairment, severe gastrointestinal issues and blood clots leading to tissue death and gangrene.

Being vaccinated does not mean that you cannot become infected with the COVID-19 delta variant. Symptoms can be milder in vaccinated individuals, so we encourage testing even if you think the symptoms are due to allergies.

Is Omicron More Transmissibleor Deadlierthan Previous Variants

From the beginning, two important questions about Omicron were top of mind for scientists, says Dr. Murray. The first is how transmissible the new variant is compared to Delta, previous variants like Alpha and Beta, and the original virus.

Based on early data from South Africa, Omicron was expected to outcompete Delta and will likely become the predominant variant strain in most places, as it is in the U.S. But questions still remain about what makes it more transmissible and how quickly it could rise to dominance, Grubaugh says.

The second question is whether Omicron is more likely than Delta or other variants to cause severe diseaseif most infections continue to turn out to be mild, rapid transmission would be less of a threat, he says.

Who Is The Most Impacted By Covid

As you probably know by now, the virus type can be especially risky for the elderly and immunocompromised, and it has also disproportionately impacted minorities, especially Black Americans, Native Americans and Alaska natives, and people who are Hispanic or Latinx. The Centers for Disease Control and Prevention notes that infection rates are higher in these populations compared to white Americans.

The issue doesn’t stop at infection ratesthese populations are also experiencing more severe symptoms and higher death rates from the virus than non-minority groups. The CDC found that Black Americans are dying of COVID-19 at a rate thats two times greater than that of white people. Mortality rates for Indigenous people, Latinx, and Pacific Islanders also have age-adjusted mortality rates of about two to 2.4 times that of white Americans.

Should We Be Worried About Delta Ay42

The emergence of Delta AY.4.2 is not a reason to worry, experts stress. However, it is a reminder of the importance of vaccination in order to prevent newand potentially more lethalvariants and sublineages from developing.

As long as we have virus transmission, there will be the evolution of new variants. You cant have one without the other, Grubaugh says. And we have vaccination as the tool to stop transmission. We just need to get more shots into arms.

Dr. Roberts agrees.

In the vast majority of cases, we need to simply stick to our standard preventive measures, which is to get vaccinated and wear masks, he says.

Is Ay42 More Transmissible Than Delta

Explained: Why is Delta variant more transmissible than other COVID-19 strains? | Coronavirus | WION

It is still unclear whether it is more transmissible or whether it is more capable of evading any immunity that we have through the vaccination, Dr Patrick Tang, the Division Chief of Pathology Sciences at Sidra Medicine in Qatar told Al Jazeera.

We dont have enough data to point one way or another.

Experts warned that the spread of the variant could be the result of a number of factors, including public health measures set out by governments or adherence to those measures.

The minor changes in the virus are almost never causing an increase in transmission. The increased transmission is really an indication of public health response or compliance to public health measures, he added.

According to Lemus-Martin, it is not clear whether its spread in the UK is a result of with biological reasons or if it is linked to the epidemiological conditions in the UK.

In the UK the current measures against COVID-19 are very lax, practically they are not following them anymore, and we dont know if that might be the reason for the spread, she added.

Unvaccinated People Are At Risk

In the U.S., there is a disproportionate number of unvaccinated people in Southern and Appalachian states including Alabama, Arkansas, Georgia, Mississippi, Missouri, and West Virginia, where vaccination rates are low, but cases are rising in other parts of the country as well. In September, health leaders in Idaho, which has one of the lowest vaccination rates in the country, expanded health care rationing throughout the state after the Delta surge led to a scarcity of resources for all hospitalized patients.

Children, teenagers, and young adults are a concern, too. A study from the United Kingdom showed that children and adults under 50 were 2.5 times more likely to become infected with Delta, says Dr. Yildirim. The U.S. has allowed Pfizer-BioNTech vaccinations for adolescents and teenagers since May, and, in early November, the CDC approved FDA authorization of the Pfizer vaccine for children ages 5-17.

As older age groups get vaccinated, those who are younger and unvaccinated will be at higher risk of getting COVID-19 with any variant, says Dr. Yildirim. But Delta seems to be impacting younger age groups more than previous variants.

Delta Variant Symptoms: What You Need To Know

Vaccination Is The Best Protection Against Delta

The most important thing you can do to protect yourself from Delta is to get fully vaccinated, the doctors say. The CDC endorses a clinical preference for vaccination with the Pfizer and Moderna shots, both of which are two-dose vaccines. You must get both of those shots and then wait the recommended two-week period for them to take full effect. All adults are eligible to be vaccinated . Boosters are also recommended.

Although fully vaccinated people with a breakthrough infection can infect others, the CDC reports that the amount of viral genetic material may decrease faster in vaccinated peopleso, while they have been found to carry the same amount of virus in their noses and throats as unvaccinated people, studies have also found they may spread virus for a shorter time.

There are additional CDC prevention guidelines available for both vaccinated and unvaccinated people. As efforts continue to vaccinate more people in the U.S., the CDC is recommending layered prevention strategies for everyone, and that includes wearing face masks in public indoor settings in areas of substantial or high transmission. The agency has also recommended universal indoor masking for all teachers, staff, students, and visitors to K-12 schools. There also may be mask mandates in place depending on your geographic location.

Cases Confirmed So Far

Explainer: What is the Delta variant of coronavirus with ...

Just a mere two months after detection of the highly contagious Omicron Covid-19 variant last November, and the threat of another big lockdown from taking over the world, there is now new evidence that another new variant has now appeared in Cyprus.

This new variant has been named ‘Deltacron‘, for being a combination of the Delta and Omicron variants. According to the professor of Biology at the University of Cyprus, Leondios Kostrikis, there are some people infected with Omicron and Delta, but in the case of this variant known in the Cypriot country, it is “a combination of both”. Kostrikis declared that the new variant has “the genetic signature of Omicron and the genomes of Delta.”

Does It Matter What Covid Strain You Have

Nope. The CDC has not issued any recommendations to differentiate between how you should act when you have one strain of COVID-19 vs. another. Currently, the Delta variant dominates COVID-19 cases in the U.S., causing about 99 percent of them, per CDC dataand the agency has not released any separate guidelines.

Theres no data that suggests the different variants cause a different length of time in symptoms, says infectious disease expert Amesh A. Adalja, MD, senior scholar at the Johns Hopkins Center for Health Security.

Omicron: A Spike In Covid

First, some background. Omicron is the latest coronavirus variant it was first identified in Botswana and South Africa in Novemberalthough later reports showed earlier cases in the Netherlands. The first case in the U.S. was reported on Dec. 1 of last year in California. By late December, it became the predominant strain in the U.S. Both the WHO and the Centers for Disease Control and Prevention have classified Omicron as a “variant of concern.”

The new variant caused an alarming spike in COVID-19 cases in South Africacases went from 300 a day in mid-November to 3,000 a day at the end of that month. Its also been identified in almost 100 other countries.

Early reports from South Africa indicate that most cases have been mildand that symptoms for this variant may be different. The reports show that patients in South Africamany of whom were younghave had severe fatigue, but no loss of taste or smell, says Lauren Ferrante, MD, a Yale Medicine pulmonologist.

Meanwhile, as people around the world welcomed a new year, Omicron surged more quickly than any previous variant in many areas. The new variant has driven a rising caseload in the U.S. that, at the end of 2021, far surpassed the record for new daily cases. However, numbers of hospitalizations and deaths were still far below what they were during previous virus peaks.

What You Can Do To Protect Yourself From Omicron

People need to understand that variants like Omicron are a natural part of the progression of the virus, Grubaugh says. The fact that there is a new variant isnt surprising, he says. Delta was never going to be the last variantand Omicron is not going to be the last one. As long as there is a COVID-19 outbreak somewhere in the world, there is going to be something new that emerges.

Both Grubaugh and Dr. Murray say the best way to prevent new variants is to get vaccinated, because if more people are vaccinated, it decreases the opportunity for the virus to spread and mutate. If you havent gotten your vaccine and booster shot yet, the CDC has endorsed choosing the Moderna and Pfizer-BioNTech vaccines.

In response to Omicron, the CDC is also urging everyone to get a COVID-19 booster shot when they are eligible. Recommendations for boosters and who is eligible to get one have been changing, and .

Meanwhile, Omicron and Delta remain threats in the U.S., and experts continue to recommend protecting against those variants by maintaining infection prevention strategies such as wearing a mask in public indoor settings in areas of substantial or high community transmission, washing hands frequently, and physical distancing from other people.

Travelers to the U.S. should continue to follow CDC recommendations for traveling and related updates in response to Omicron. Doctors advise people who are planning trips to consider travel insurance.

What Is The Treatment For The Covid

Delta variant becoming globally dominant form of COVID-19 | ABC News

There is currently no cure for COVID-19 and the goal of treatment is to relieve symptoms in mild to moderate cases. Treatment is the same regardless of the infectious variant.

Patients with mild to moderate illness are usually advised to remain home and self-isolate for up to 14 days to avoid spreading the virus. Treatments for mild to moderate COVID-19 symptoms include:

  • Rest

Viral Load And Transmission

There is also another considerationthe role viral load may play in transmission. A study published in February 2021 in The Lancet Infectious Diseases found that the viral loadthe amount of virus in a persons body is a critical factor in the transmission of SARS-CoV-2.

Specifically, the study concluded that those with higher viral loads are more likely to transmit the virus to others. In March, another study from Israel found that the Pfizer-BioNTech vaccine, even after just a single dose, significantly reduced viral loadwhich suggests that it may also lower the risk of transmission. But it did not evaluate whether vaccinated people could transmit the virus, even if their viral loads were reduced. Nor did it take into account the Delta variant.

More science will certainly emerge on transmission, as the Delta variant circulates and as more people become vaccinated, and hopefully public guidance will follow the science,” says Dr. Meyer.

A recent study, which has not yet been peer-reviewed, demonstrated that people infected by the Delta variant had viral loads roughly 1000 times higher than those infected by the initial strain of the virus.

“The higher viral loads may play a role in increasing the risk of transmission, because each droplet can be packed with more virus,” says Dr. Meyer.

But the extent to which it does so in unvaccinated and vaccinated people is still unclear.
