The novel coronaviruses belong to the B 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 ofinfection; 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. This kit is used for in vitro qualitative detection of novel coronavirus 2019-nCov in respiratory specimens including oropharyngeal swab, sputum, bronchoalveolar lavage fluid and nasopharyngeal swab. Primer sets and FAM labeled probe are designed for specific detection of ORFlab gene of 2019-nCov. VIC labeled probe for N gene of 2019-nCov. Human RNase P gene extracted concurrently with the test sample provides an internal control to validate nucleic extraction procedure and reagent integrity. Probe targeting human RNase P gene is labeled with CY5.
