In December 2019, Wuhan, in Hubei province, China, became the center of an outbreak of pneumonia of unknown cause. In a short time, Chinese scientists had shared the genome information of a novel coronavirus (2019-nCoV) from these pneumonia patients and developed a real-time reverse transcription PCR (real time RT-PCR) diagnostic assay.

In view of the fact that there is currently no effective antiviral therapy, the prevention or treatment of lung injury caused by COVID-19 can be an alternative target for current treatment. Xiyanping injection has anti-inflammatory and immune regulation effects. This study is a Randomized, Parallel Controlled Clinical Study to treat patients with COVID-19 infection.

The new coronavirus (COVID-19) [1] belongs to the new beta coronavirus. Current research shows that it has 85% homology with bat SARS-like coronavirus (bat-SL-CoVZC45), but its genetic characteristics are similar to SARSr-CoV. There is a clear difference from MERSr-COV. Since December 2019, Wuhan City, Hubei Province has successively found multiple cases of patients with pneumonia infected by a new type of coronavirus. With the spread of the epidemic, as of 12:00 on February 12, 2020, a total of 44726 confirmed cases nationwide (Hubei Province) 33,366 cases, accounting for 74.6%), with 1,114 deaths (1068 cases in Hubei Province), and a mortality rate of 2.49% (3.20% in Hubei Province).

In view of the fact that there is currently no effective antiviral therapy, the prevention or treatment of lung injury caused by COVID-19 can be an alternative target for current treatment. Xiyanping injection has anti-inflammatory and immune regulation effects. In the early clinical practice of treating severe H1N1, it was clinically concerned, and combined with conventional treatment, and achieved good results.
