Omikeron seems to be even trickier than we think.
On January 8, 2022, tianjin added two new cases of local infection, which were tested and confirmed to be positive for Omikerong infection, which is also the first case of infection of the indigenous Omikejong virus strain in China.
As of January 12, Tianjin has reported a total of 137 cases of positive infection of the new crown virus, of which 76 cases have been confirmed locally, 17 cases of asymptomatic infection, and 44 cases of positive infection after initial screening.

At the same time, the new local epidemic situation in Anyang, Henan and Dalian, Liaoning, is related to the spillover of the epidemic in Tianjin.
At the same time, Aumiqueron has also been "raging" around the world, and a total of 128 countries and regions may also have Cases of Aumiqueron.
What are the difficulties in this epidemic?
First, Most of the Omikejons are asymptomatic or mildly infected
Previously, relevant data showed that the symptoms of Omi kerong were mild, the difficulty of finding was large, the transmission was strong, and most patients with mild diseases stayed at home, resulting in family transmission.
It was only when a severely ill patient was seen to be seen, but a chain of transmission had already been formed before that.
The epidemic in Tianjin, through epidemiological investigation, shows that the epidemic in Tianjin has long existed in the community during the New Year's Day holiday, because the custody class did not have a holiday during the holiday, and the children participating in the custody class have been exposed to the virus.
It was not until the start of the school year on January 4 that the children brought the virus back to their respective schools, causing infection in the class or other classes, and the students in the same class were infected and brought the virus back to their families, which was dispersed to different communities.
Second, the source of the virus and its transmission route are unclear
Compared with the infectivity of Delta virus, the infectivity of Omikejon is more contagious, so this is also the current epidemic in the primary and secondary school students and other young age infected groups are relatively high.
The positive window of the Omiljung virus is short, the viral load is low, not only can not determine whether there is a chain of transmission that has been detected, but also from the existing virus gene sequencing, the sequence of the strains of the cases that have not yet been picked from Tianjin has homology.
But this does not mean that the possibility of importation from abroad can be completely ruled out, and Omicron is not simply through people, but also through things, as well as the environment.
And the clues in this regard also need to be traced synchronously, and further digging and digging deeper.
The appearance of these symptoms requires you to report it immediately to the doctor
It is now the end of the year, and it is also in the season of high epidemic incidence. If in daily life, there are suspected symptoms of the epidemic, it is necessary to seek medical attention as soon as possible and take the initiative to test nucleic acid for verification.
First, repeated low-grade fever
If you have traveled, or come into contact with some outsiders, or frequently go in and out of some public places during the holidays, once the phenomenon of low-grade fever occurs repeatedly, you must be vigilant, and after being infected with new crown pneumonia, the first symptom of most patients is repeated fever.
The fever caused by COVID-19 is not severe and generally does not exceed 37 degrees5. However, there are also patients who experience a phenomenon between 38 and 39 degrees.
Second, repeated dry cough
After contracting the novel coronavirus, patients will have repeated coughing. This cough is especially pronounced when fever symptoms occur.
When coughing, patients do not cough up sputum at all, and only a few patients cough up a small amount of sticky sputum. Generally, when a dry cough occurs, most patients will also be accompanied by sore throat.
Third, the body is weak
Physical weakness is also a major symptom of infection with the new coronavirus pneumonia. Even if the patient does not have repeated coughs, fevers, etc., the overall physical strength will show a decline.
This physical weakness is not very severe, but it is persistent. Even if the patient does not perform some heavy physical activity, symptoms such as limb weakness, physical exhaustion, and mental malaise will still occur.
Fourth, gastrointestinal symptoms
Some patients with new crown pneumonia do not have fever, cough and other phenomena, but will show a series of digestive symptoms, such as repeated diarrhea and loss of appetite, or nausea and vomiting, abdominal pain and other symptoms.
The virus in the body will produce a large number of toxins in the body, and these toxins will stimulate gastrointestinal function, resulting in gastrointestinal dysfunction.
As a result, patients will have repeated diarrhea.
Fifth, the chest is suffocated
Many patients with new coronary pneumonia will have chest tightness and difficulty breathing. This chest stuffiness is very pronounced especially when coughing and weakness and low-grade fever occur.
In severe cases, it may even be accompanied by shortness of breath, shortness of breath, and even symptoms of dyspnea.
If there are suspected symptoms, it is necessary to quickly do self-isolation as soon as possible, and go to a regular hospital for treatment, while avoiding public transportation, and do the corresponding protective isolation measures.
