The newest neocoronavirus is now omicron, which infects some asymptomatically infected individuals with positive symptoms such as fever, cough, abdominal pain and diarrhea, muscle aches, and nasal congestion.
The Omicron variant is more infectious, spreads more rapidly, has atypical clinical symptoms, and has the ability to evade the binding of neutralizing antibodies and the protective effect of the new crown vaccine.
1. Stronger infectiousness and faster transmission: The omicron variant is more likely to cause human infection and spread among the population. Through our epidemiological analysis of the existing cases, the average intergenerational distance between omicron infected cases is 3 days, which is further shortened than that of the delta variant (about 4 days), and its transmission ability is about twice as much as that of the delta variant, so the transmission ability is stronger and the transmission speed is also faster. faster.
2. The symptoms of omicron infection are atypical, so it is more subtle in the process of transmission. In terms of clinical manifestations, omicronjon infections are similar to upper respiratory tract infections caused by other viruses and lack specific manifestations, which makes clinical differential diagnosis difficult and makes the spread of the virus more insidious.
3. Infected cases are mainly light and common type, and the symptoms are relatively mild. The main clinical manifestations include cough, sore throat, fever, etc., and some patients have symptoms such as nasal congestion, runny nose, fatigue, headache, etc. Therefore, when and if a patient with Omicronjon strain infection has symptoms of upper respiratory tract infection, the symptoms are similar to those of other viruses, lacking specific manifestations.
Therefore, when there is a history of close contact with the new crown patients, if the above symptoms appear, must promptly go to the hospital.
