Symptoms of Omicron: How is it different from Covid-19 Variant Delta?

Panic over omicron has increased around the world as it is spreading faster than other variants of the corona. Moreover, omicron has the ability to infect many people quickly in less time. However, compared to the previous deadly variant Delta, the symptoms of omicron are much milder. Scientists have already begun extensive research into this variant identified in South Africa, which is now available all over the world. However, the researchers have already found out the omicron symptoms. Let’s get to know the omicron symptoms and how this variant is different from the delta variant.

Symptoms of Omicron

Mild to moderate symptoms are observed in those affected by omicron. Further, the death and hospitalization rates are also somewhat lower. But even then, medical experts are reluctant to take it lightly. Because, through such, the corona is sustaining its existence. Can it be said for sure that it will not emerge as a terrifying new variant at any time?

Omicron is quite different from the original types of the corona. It was first found in South Africa last November. After that, it spread rapidly in many countries of the world. A recent study found that omicron inherited some genetic traits from the common cold virus outside its genus. Although the virus is not deadly, everyone should be aware of the symptoms.


Similar to previous variants, omicron can cause fatigue or extreme fatigue. A person may experience excessive fatigue, lack of energy, and a strong desire to rest, which can disrupt his daily activities. However, it should be kept in mind that not only because of covid but also other causes and health problems can make anyone feel tired. That is why it is necessary to do the covid test to be sure of your physical condition.

Sore Throat

People infected with omicrons are experiencing sore throats, which is unusual. The former variant is associated with pain in the throat and full body.

Mild Fever, Goes Away on its Own

Mild to moderate fever has been one of the symptoms of covid since the onset of the novel coronavirus. But although the previous strain fever had a long-term effect on patients, omicron brings a lighter temperature to the body then goes away on its own.

Sweating and Body Aches at Night

Night sweats can be one of the symptoms of the Omicron variant. As per the reports, the patient may feel sweaty at night even if the person sleeps in a cool place. The clothes and bed will get wet too. According to doctors, this can be accompanied by other symptoms, including ‘severe body aches.’


Omicron patients may also experience dry cough, which was also the most common symptom of previous other strains.

Congestion or Runny Nose

During the recent omicron wave, it was noticed that a runny nose or congestion in the nose was a commonly reported symptom. However, the flu season is also going on, so it is difficult to say if a runny nose or congestion is a definitive omicron symptom. But, it can be one of the symptoms. Hence, it is advised to do the covid test if you have such problems.

How is Omicron Different from Delta?

Although both Omicron and delta are covid-19 variants, they are different from each other. According to experts, fatigue, joint pain, chills, and headaches are the four symptoms of omicron that differ from Delta. Furthermore, losing taste and odor, one of the symptoms of Delta, is occasionally found in the case of COVID variant omicron.

Omicron may not have the same difficulty as Delta, but this can infect the lungs. Unlike Delta, omicron may cause less damage to the lungs.

Omicron is highly transmissible and has already broken the record for daily infection rates. Although it is not deadly, the infection rates are exponentially increasing compared to Delta.

Another thing is that Omicron sufferers rarely lost their taste buds, while it was common for Delta. Even in this variant, the oxygen level in the corona patient’s blood does not drop suddenly.

There are differences in the incubation period too. A small study by the Centers for Disease Control has found that the incubation period for omicron is 3 days while it is 4 days for Delta.

How Long Does It Take for the Omicron Symptoms to Appear?

Imagine Covid entering your body today. However, the symptoms will not appear right away. It will then take possession of one cell at a time and begin to replicate itself. After a while, if the body’s immune system loses to this disease, the symptoms will appear.

The question is, how long is this time? Experts have found that in the case of the previous variants, the symptoms appeared within 5 to 6 days after the virus entered. In some cases, the symptoms appeared within 14 days.

However, in the case of omicron, the symptoms appear within 2 to 10 days. Hence, the omicron symptoms show up faster than any other corona variants.

What to do If you have omicron Symptoms?

If you think you have omicron symptoms, isolate yourself first and consult a doctor immediately. Do the covid test and follow the Covid rules. The mask must be worn maintaining all the rules. Wash your both hands properly using sanitizer or soap for at least 20 seconds.

How to Prevent Covid-19 Variant Omicron?

To prevent omicron, one should follow the regular covid-19 protocols. For example, maintaining one meter physical distance, wearing a good quality mask, keeping the windows open for proper ventilation, avoiding the crowded place, using tissues in the case of cough or sneeze, and keeping hands clean.

Final Words

Omicron is considered less deadly than the delta variant. But in terms of infection, it has surpassed the Delta as well. Omicron is now the most influential type of coronavirus all over the world. So, knowing the symptoms will help us to stay alert about omicron.
