What are the early symptoms of Omicron? Is the mortality rate of Omicron high?

As of now, multiple countries and regions such as Australia, Austria, Canada, Czech Republic, Denmark, and Germany have experienced Omicron. So, what are the early symptoms of Omicron?

Early manifestations of Omicron

1. Fatigue

Some patients may experience symptoms of general fatigue after being infected with the Omicron strain, and some patients may feel general fatigue. At this time, it is best to go to the hospital for examination to determine whether they are infected with the virus.

2. Muscle Pain

After contracting the Omicron variant, some patients may experience muscle soreness, just like a cold, with soreness in every area. However, if there are no other symptoms, there is no need to worry about it. When suffering from influenza or common cold, there will be pain in the whole body.

3. Itchy Throat

After being infected with the Omicron variant, patients may feel itchy and painful in their throat, but due to various reasons, it can be caused. If there are no other symptoms, there is no need to worry. But if you have had contact with the Omicron variant recently, you must take it seriously and go to the hospital for nucleic acid testing in a timely manner.

4. Mild Cough

After contracting the Omicron variant, a small number of patients may experience mild coughing, sometimes with phlegm in their throat, but they cannot cough it out, which may be due to a common cold or pharyngitis. After contracting the Omicron variant, some patients may experience symptoms of runny nose, but if there are no other symptoms, treatment is not necessary. For example, patients with common cold, frostbite, and other conditions may have a runny nose, so simply having a runny nose is not a big deal.

6. Headache

After being infected with the Omicron variant, a small number of patients may experience symptoms of headache, but it cannot be one-sided. It should be judged based on the symptoms, such as migraine patients occasionally experiencing headaches. How contagious is Omicron?

The infectivity of Omikron is 37.5% higher than that of Delta. Omikron is still a kind of COVID-19, and it needs to be tested from structural virology, cross immune neutralization, field epidemiology, etc. Recently, there was a news circulating online that the COVID-19 Omicron variant virus is more difficult to detect. The news stated that it is necessary to wear a mask because the new COVID Omicron variant coronavirus is different from other coronaviruses in that it is more deadly to detect and difficult to accurately detect. It does not cause coughing or fever. The toxicity of COVID Omicron is five times that of Delta variant, and the death toll is also higher than Delta variant.

Is that really the case? Is it difficult to detect the COVID Omicron variant virus? The Omicron variant is mainly characterized by mutation sites. In China, the primers and probes for nucleic acid detection mainly target the ORF1ab gene and N gene, both of which are stable. Therefore, the sensitivity and specificity of mainstream nucleic acid testing reagents in China remain unchanged and can be used to deal with the Omicron variant.

COVID Omicron is 5 times more toxic than Delta and has a higher mortality rate than Delta? Compared to Delta, the difficulty of Omicron's dissemination is still unclear. Can Omicron cause more serious illnesses? More data is needed to understand Omicron infection regarding this issue.

WHO says: It is unclear whether infection with Omicron causes more severe disease than infection with other variants, including Delta. There is currently no data showing that Omicron related symptoms differ from other variants. The existing vaccines are still suitable for critically ill patients.
