EZER Flu&COVID-19 Antigen Combo Rapid Test is intended for the simultaneous qualitative detection and differentiation of the nucleocapsid protein antigens from SARS-CoV-2, influenza A and influenza B in direct nasal specimens. The detection is based on the antibodies which were developed specifically recognizing and reacting with the nucleoprotein of virus.
Introduction
Influenza virus belongs to the family of Orthomyxoviridae, and immunologically diverse, single-stranded RNA viruses. There influenza A and B virus is the main pathogen that severe illnesses both in human and in many animal species. Based on the current epidemiological investigation, the incubation period is 1 to 4 days. The main manifestations include acute fever, general aching and respiratory symptoms. Both Type A and B viruses can circulate simultaneously, but usually one type is dominant during a given season.
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.
Clinical signs and symptoms of respiratory viral infection due to SARS-CoV-2 and influenza can be similar. SARS-CoV-2, influenza A and influenza B viral antigens are generally detectable in upper respiratory specimens during the acute phase of infection.
