2. A scientific approach

The dynamic clearing policy China has adopted is a scientific approach to fighting the novel coronavirus in line with its national conditions.

It is wrong to consider the Omicron variant of the virus as no worse than the virus that causes the common flu.

It is irresponsible for some politicians to compare infections of the Omicron variant to a "flu" because it is not supported by any scientific evidence. They do so out of a cynical need to cover up their failure in responding to it.

No mainstream health experts have argued Omicron should be regarded as just another flu. It is mainly politicians in countries where the pandemic spread out of control who are doing that.

3.A timely strategy

Dynamic clearance measures change in accordance with the situation. If an outbreak is detected early, health workers only need to quarantine and treat patients while keeping an eye on quarantined close contacts.

Under the policy, so long as there is no community spread it is acceptable for cases to exist in quarantine because they are temporarily isolated.

In such a way, the spread of the virus can be kept at bay to avoid the large number of deaths the virus would otherwise cause among the aged or those with chronic diseases.
