Hainan, Tibet and other regions have successively experienced epidemics, showing three characteristics, which are different from previous epidemics
Recently, domestic epidemics have occurred in many provinces and cities one after another, showing a continuous and continuous trend. When examining these areas where epidemics occurred, some different characteristics can be found, as follows.
First, this wave of epidemics occurs more in tourist cities and regions. Cities with greater population mobility have greater risks, such as Sanya and Tibet, although the investigation found that the virus was imported However, the frequent population gatherings and dispersal results in the rapid spread of the virus.
Second, different regions have different virus strains. The virus detected in Sanya this time is BA.5.1.3, and the virus detected in Tibet is BA.2.76, showing different viruses. The characteristics of the coexistence of these virus strains indicate that the infectivity and immune escape ability of these virus strains have reached a certain high level.
3. Summer is no longer the dormant period of the virus. The virus no longer clearly enters the dormant state in summer like the first-generation new coronavirus, but continues to be prevalent in a certain area without any precautions. Control may still cause a relatively large-scale epidemic, so it should not be taken lightly.
