COVID-19 Respiratory Diseases |
Coronaviruses belong to the family of enveloped RNA viruses. In humans, they cause diverse clinical pictures, from the common cold to severe respiratory syndromes (MERS, SARS, and COVID-19). SARS-CoV-2, the cause of COVID-19, is a respiratory virus discovered in 2019. It is primarily transmitted to an individual through close contact with an infected person, during which infectious droplets spread to the environment. Symptoms of COVID-19 are highly variable, ranging from none to life-threatening illness.
The SARS-CoV-2 virus contains four structural proteins: spike (S), nucleocapsid (N), envelope (E), and membrane (M) protein. Responding to the infection, the human immune system raises specific antibodies, starting with IgA and IgM. The IgG antibodies represent a later matured response. Serological tests play only a supporting role in COVID-19 diagnosis. However, they are effective in assessing the immune response of an individuum or population.
Nucleocapsid protein (NP) encapsulates viral genomic RNA and forms a major component of the viral structure. NP is a highly antigenic epitope, which is highly conserved and does not change when the virus is mutated. In patients who have had COVID-19 infection, the anti-NP antibodies are usually measured at higher levels than antibodies to other SARS-CoV-2 proteins.
