The Omicron variation, according to experts, has several symptoms with other COVID-19 variants, particularly those that impair the upper respiratory system.
- Fever, cough, and headache are said to be some of the most prevalent symptoms. Muscle pains are also common.
- People who have been diagnosed with Omicron, on the other hand, have not reported a substantial loss of taste or smell.
- Omicron symptoms, according to experts, seem to be very moderate thus far, especially in persons who have been vaccinated.
Omicron can spread quicker because it remains in the nose and throat, although it looks to be less lethal than prior forms. Symptoms may also vary.
What are the signs and symptoms of Omicron?
According to studies, the most prevalent symptoms produced by Omicron are identical to those caused by other variations.
These are some of them:
- runny nose
- sore throat
Muscle pains seem to be prevalent as well.
“Omicron tends to induce a dry/scratchy sore throat, sneezing, headache, muscular pains, exhaustion, and runny nose/congestion in vaccinated and boosted patients,” Dr. N. Adam Brown, chief impact officer and COVID-19 Task Force chair at Envision Healthcare.
“A dry cough and fever are also possible side effects of Omicron, although they are less prevalent than with older forms,” he noted. “The majority of individuals who become sick have a dry sore throat, body pains, and a headache,” Brown said. “For a few days, such symptoms develop.”
Omicron seems to be less likely to cause loss of taste and smell. Lung disorders that are severe are also uncommon. “We’ve been hearing fewer reports of loss of taste or smell in our [patient] interviews recently, and more reports of sore throat, runny nose, headaches, sneezing, and fatigue,” said David Souleles, MPH, director of the COVID-19 Response Team and director of the Masters in Public Health Program and Practice at the University of California Irvine. “However, if you are suffering any COVID-19 symptoms, it is critical that you be tested as soon as possible.”
Unvaccinated persons get more severe symptoms.
People who have been vaccinated are more prone to develop Omicron symptoms similar to a regular cold. Even with the normally milder Omicron version, unvaccinated persons and those with impaired immune systems have a greater risk of getting the severe disease from COVID-19.
“Unvaccinated persons… tend to have more protracted and worse symptoms, beginning with cold-like symptoms and advancing to severe respiratory symptoms, coughing, painful body aches and headaches, trouble breathing, pneumonia, respiratory failure, and even death,” Brown added.
Symptoms may be less severe
Although Omicron is the most infectious coronavirus variety to date, it does not seem to be as lethal as previous variants such as Delta. That’s because Omicron prefers to linger in the upper respiratory system rather than settling in the lungs, where it might do greater harm, according to researchers.
“Studies have shown that Delta particles land in the lungs and harm lung tissue far more quickly, resulting in pneumonia,” Brown said. “Omicron, on the other hand, prefers to settle in the upper airways” (nose, throat, and bronchi). One of the key reasons why symptoms vary is where the virus lands.” According to Brown, both the intensity of the disease and the time of infection seem to be reduced for Omicron, particularly among individuals who have been vaccinated and boosted.
“However, despite the fact that some of these symptoms seem to be less severe, Omicron spreads up to three times quicker than Delta,” he stated. “As a consequence, more people are being infected, and more patients are going to the hospital for examination and treatment.” “To be clear: Omicron patients are overrunning hospitals,” he continued, “suggesting that the Omicron version is not moderate to individuals who are unvaccinated, unboosted, and immunocompromised.”
A spread is a collection of both positive and negative news
Omicron may provide an elevated risk of reinfection for persons who have previously had COVID-19, in addition to spreading more readily among both vaccinated and uninfected people. The fact that Omicron spreads more readily yet has milder symptoms than other varieties isn’t altogether good news, according to Jennifer Horney, Ph.D., founding director, and professor of the epidemiology department at the University of Delaware.
“How many people will be checked if it has milder symptoms?” she wondered. “The virus wants to infect others, and if people don’t become sick as much, the infection will spread more quickly since people are out and about.” This might bring the population closer to COVID-19 herd immunity, although Horney cautioned that the benefits could be restricted by the fact that natural coronavirus protection fades fast.
