The claim that New Crown cures itself in 8 days is one-sided. Asymptomatic and mildly infected people can generally cure themselves but still need to be quarantined, while common and severely infected people generally cannot cure themselves and need to be treated for their condition. The so-called 8-day self-healing of new crowns is one-sided, not all new crowns infected people can be self-healed in 8 days. In the case of asymptomatic and mildly infected patients with relatively mild symptoms and relatively low viral load in the body, most of them can recover from the disease by focusing on isolation, which usually takes 1~2 weeks. However, if the infected person is ordinary type and serious disease, especially the people with serious underlying diseases, the condition is relatively serious, then it is necessary to combine scientific and systematic treatment, there is no fixed treatment period, based on the change of the infected person’s condition, to achieve two consecutive negative nucleic acid test can be discharged, generally need 1~2 months or even longer time.
