On November 24, scientists in South Africa discovered a novel coronavirus (or SARS-CoV-2) strain known as Omicron (or B.1.1.529).
The most recent form of the virus that causes COVID-19 illness is more transmissible than the Delta variant, which is already highly infectious. According to the WHO, Omicron has been found in 106 countries.
The list of Covid-19 symptoms has become more extensive and wilder throughout the pandemic. Because so many individuals have been vaccinated, the symptoms of an illness have become milder and hazier.
As the omicron form gallops over the world, pushing through the nooks and crannies in the wall of immunity that has been erected over the previous two years is becoming increasingly clear.
What Are the Most Prevalent Omicron Symptoms?
Muscle pains, weariness, a scratchy throat, and night sweats are frequent Omicron symptoms.
Cold-like symptoms were the most often reported by those with the novel Omicron variety, according to early data provided by the COVID Symptoms Study, which is managed by the health science business Zoe and King’s College London.
According to the data, a runny nose, headache, weariness (moderate or severe), sneezing, and a sore throat were the top five symptoms reported in the app for Omicron infection.
The World Health Organization’s senior official in Europe, Hans Kluge, noted that 89 percent of patients in Europe with confirmed Omicron infections had symptoms similar to other coronavirus variations, such as cough, sore throat, and fever.
Like the Delta variant, the Omicron variant can alter the frequency or severity of symptoms. However, additional information is required to be definite.
According to Scott Roberts, MD, Yale Medicine infectious diseases expert and assistant professor of medicine at Yale School of Medicine, “preliminary findings show individuals infected with the Omicron variety exhibit comparable symptoms to other variations of SARS-CoV-2.”
“There have been anecdotal accounts of instances being milder and patients having no loss of taste or smell, but these reports should be regarded with care until additional evidence is available.”
Are the Symptoms of Omicron Milder Than Those of Other Variants?
Coetzee describes Omicron’s symptoms as “very, very minor.” Patients have not experienced a loss of smell or taste, and there has been no significant decline in oxygen levels with the new version, unlike with earlier variants, she added.
Research from South Africa, which has not yet been peer-reviewed, suggests that patients infected with the Omicron coronavirus strain had a decreased probability of being admitted to the hospital and severe disease than those infected with the Delta variant.
However, the authors note that some of this is likely due to high population immunity.
“We find no indication (for both chance of hospitalization attendance and symptom state) of Omicron having different severity from Delta,” researchers at Imperial College London (ICL) noted, adding that data on hospitalizations is sparse. Their research has not yet been peer-reviewed.
Experts are also afraid that the rapid spread of Omicron would cancel out any improvement in severity.
Vaccines: What Effect Do They Have on Symptoms?
According to experts, the signs of Omicron infection in vaccinated persons may be much less than in unprotected people, leading to ignored instances.
“Growing data reveals that patients who’ve had two doses of the vaccination often appear with fewer severe symptoms for example headache, runny nose, sneezing, sore throat, and loss of smell,” said Officials of RSPH.
“It’s critical for those who have been completely vaccinated to be on the lookout for cold-like symptoms and to be tested if they live or work around persons who are more susceptible to the disease.”
Early evidence suggests that current vaccinations may provide less protection against Omicron infection.
Research revealed that an initial two-dose vaccination course gave less protection against mild sickness from Omicron than the Delta strain, according to the United Kingdom’s Health Security Agency (UKHSA).
On the other hand, Boosters were shown to partially restore protection, providing an estimated 70 percent to 75 percent protection against moderate illness caused by the new Omicron type.
Prevention Against Omicron:
To protect oneself and prevent the spread of COVID-19, the WHO recommends taking the following steps:
- Vaccinate yourself.
- Put on a mask.
- Maintain physical distance between you and the other person.
- Indoor places should be ventilated.
- Maintain proper hygiene.
- If you start to have symptoms, separate yourself.
