The novel coronaviruses belong to the p genus. COVID-19 is an acute respiratory infectious disease. People are generally susceptible. Currently, the patients infected by the novel coronavirus are the main source of infection; asymptomatic infected people can also be an infectious source. Based on the current epidemiological investigation, the incubation period is 1 to 14 days, mostly 3 to 7 days. The main manifestations include fever, fatigue and dry cough. Nasal congestion, runny nose, sore throat, myalgia and diarrhea are found in a few cases.
Antigen is generally detectable in upper respiratory specimens during the acute phase of infection. Rapid diagnosis of SARS-CoV-2 infection will help healthcare professionals to treat patients and control the disease more efficiently and effectively.
The Coronavirus Ag Rapid Test Cassette (Swab) is
an in vitro immunochromatographic assay for the qualitative detection of
nucleocapsid protein antigen from SARS-CoV-2 in nasopharyngeal (NP) swab specimens
directly or after the swabs have been added to viral transport media from
individuals who are suspected of COVID-19 by their healthcare provider. It is
intended to aid in the rapid diagnosis of SARS-CoV-2 infections.
