Novel coronavirus COVID-19 is a new acute respiratory infection that is generally susceptible to the public. At present, the main source of infection is newly infected patients, and asymptomatic infected person may also be a source of infection. 

Influenza virus is divided into three types, A, B, C, is a type of RNA virus that causes influenza in human and animal, It can rapidly spread through air that, in many circumstances, cause periodic epidemics around the world. The main circulating types of influenza viruses are type A and B. Nucleic acid testing is a rapid and effective means to distinguish between influenza and other types of colds. 

Respiratory syncytial virus (RSV,family Paramyxoviridae) is an RNA virus that can be divided into two subtypes: A and B. RSV subtype A infection is acute and severe while subtype B infection is relatively mild. RSV is the most important viral pathogen responsible for acute lower respiratory tract infections in children under 5 years old. RSV infection is the primary cause of hospitalization in infants. RSV infection does not produce permanent immunity and does not protect children from reinfection.

• Multiplex fluorescence detection technology, multiplex testing in one tube, accurate identification of COVID-19, FluA, FluB, RSV (A / B)

• The gold standard of viral detection, can quickly and accurately provide diagnostic data for related viral infection, Shorten the pathogen testing timein the cases of mixed infection

• Accurate classification, effective treatment and triage of fever patients for hospital fever clinics and outpatient and emergency departments, and efficient allocation of medical resources
