[Omicron / Mortality / Symptoms / Sequelae] The Omicron new coronary pneumonia variant virus is raging around the world. Due to the symptoms of Omicron infection, such as sore throat, fever, etc., similar to the flu and common cold, some even "asymptomatic" The probability of severe disease is low, and it is even pointed out that Think of Omicron as a cold.
Is Omicron really a common cold?
According to the latest research report of the US Centers for Disease Control and Prevention (CDC), although Omicron has a large transmission capacity and a large number of infected people, the hospitalization days and the previous wave of high infectivity variants such as Delta are not as serious. The hospitalization days are shorter and the severe cases are less. The death rate is also lower.
However, although the death rate of Omicron is lower than that of Delta, according to the South Korean study, the death rate of Omicron is still slightly higher than that of influenza, so it must not be taken lightly.
Omicron's new coronary pneumonia variant is heating up the global epidemic.

According to the latest research report of the US Centers for Disease Control and Prevention (CDC), the number of confirmed cases of new coronary pneumonia under Omicron has increased sharply, but the severe rate is about 29% lower than the peak of the epidemic last winter, and about 26% lower than that of the Delta epidemic.
In terms of mortality, the study pointed out that from December 19 last year to January 15 this year, during the peak period of Omicron infection, there were an average of 9 deaths per 1,000 patients, with a mortality rate of 0.9%, which was also higher than the peak of the previous winter (1.6%) and Delta. Peak (1.3%) low.
However, the study also pointed out that the lower proportion of severe cases of Omicron variants may be related to higher vaccine coverage, the number of people who received the third shot, and the immune protection of patients who had been infected.
Can Omicron be used for flu, common cold?
The latest research report of the US Centers for Disease Control and Prevention (CDC) did not compare Omicron and influenza data, but according to Yonhap News Agency, data from the South Korean Central Epidemic Prevention Headquarters showed that the domestic Omicron infection mortality rate was about 0.16%, which is equivalent to the Delta mortality rate of 0.8% However, it is still higher than the 0.1% mortality rate of influenza, so Omicron is significantly higher risk than influenza.
6 Sequelae of New Coronary Pneumonia Do Not Ignore
The British app "ZOE Novel Coronavirus Disease Symptom Study", which regularly updates the common symptoms of Omicron infection, found that 1 in 4 Omicron patients developed "brain fog".
"Brain fog" belongs to cognitive dysfunction. Symptoms such as memory loss, confusion, difficulty concentrating, dizziness and forgetting of daily vocabulary, etc., may impair future work ability and daily self-care ability, and may become "dementia" in severe cases.
In addition, a study by the Faculty of Medicine of CUHK analyzed the conditions of 106 patients with COVID-19 and found that up to 76% of patients with COVID-19 developed at least one symptom within 6 months of recovery. The most common symptoms included fatigue (31%), poor memory (28%), and hair loss. (21%), anxiety (21%) and difficulty sleeping (21%).
These sequelae affect daily life at any time, so it cannot be ignored.
