ANALYSIS OF CLINICAL AND LABORATORY INDICATORS OF MYOCARDITIS AND MYOPERICARDITIS IN PATIENTS WITH COVID-19.

In December 2019, a new respiratory infection caused by a previously unidentified strain of coronavirus, named SARS-CoV-2, was identified in China. This virus belongs to the Coronaviridae family, Nidovirales, and is characterized by a pleomorphic structure with crown-like spikes on its surface, which is why it was named "coronavirus". The size of the viral particles varies from 80 to 160 nanometers, and the genome length, expressed as positive-sense RNA, ranges from 27 to 32 kilobases. The emergence of SARS-CoV-2 led to a global pandemic, named COVID-19.2019年12月，中国境内首次发现由一种此前未被鉴定的冠状病毒毒株引发的新型呼吸道传染病，该毒株被命名为严重急性呼吸综合征冠状病毒2型（SARS-CoV-2）。该病毒隶属于套式病毒目（Nidovirales）、冠状病毒科（Coronaviridae），具有多形性结构，表面带有类似皇冠的棘突，这也是其被称为“冠状病毒”的原因。病毒颗粒的尺寸介于80至160纳米之间，其基因组为正链核糖核酸（positive-sense RNA），长度范围为27至32千碱基。严重急性呼吸综合征冠状病毒2型的出现引发了一场被命名为新型冠状病毒肺炎（COVID-19）的全球大流行。
