Human influenza A/B are enveloped negative-sense RNA viruses with a mostly spherical morphology (diameter between 80 and 120 nm). Influenza is highly contagious respiratory infection with different transmissions ways : direct transmission, the airborne route and through hand-to-eye, hand-to-nose, or hand-to-mouth transmission, either from contaminated surfaces or from direct personal contact (handshake). The relative importance of these modes of transmission is unclear, and they may all contribute to the spread of the virus. Most severe symptoms are associated with influenza A viruses. Influenza B viruses are antigenically more stable than influenza A, explaining they cause less severe epidemics. The most common symptoms typically begin two days after exposure to the virus and include a high fever, runny nose, sore throat, muscle pains, headache, coughing and feeling tired. Complications of influenza may include viral pneumonia, secondary bacterial pneumonia, sinus infections... ultimately resulting in death.
R-DiaFluTM is a trusted and easy-to-use molecular diagnostic CE-IVD kit allowing the qualitative detection by the real-time PCR of human Influenza virus A and B in clinical specimens (nasopharyngeal swabs in GLY Medium) from patients potentially infected by these viruses.
