Coronaviruses are single-stranded, positive-sense RNA viruses with outer membranes, which are important pathogens of humans and vertebrates, and can cause many acute and chronic diseases.
On February 1, 2020, the International Committee on the Taxonomy of Viruses named the new coronavirus as SARS-CoV-2. The infected people will have acute and severe respiratory diseases, accompanied by fever, cough, shortness of breath and dyspnea, and severe cases will lead to renal failure and even death.
SARS-Cov-2 IgM/IgG Antibody Detection
When a body is infected with the new coronavirus, the specific protein of the virus stimulates the immune system and leads to an antibody response. The first antibody is IgM and appears at the onset of the immune response and is followed by IgG as the infection progresses. The IgM antibody will decline and go away as the infection declines, but the IgG antibody will remain active for an extended period. The simultaneous detection of both the IgM and IgG antibodies can be used in the auxiliary diagnosis of new coronavirus infection.
