The Definition of Influenza Virus and the Classification of Influenza
Influenza is an acute respiratory infection caused by influenza virus, which is more common in winter and spring.
Clinical symptoms are a high fever, fatigue, headache, systemic pain and other systemic symptoms. In contrast to household thermometers, a dedicated disposable skin temperature probe can be used to measure the real time temperature of flu patients more accurately and facilitate later treatment.
Influenza virus also called myxovirs, name originated in the meaning of the Greek “myxo” mucus. As the earliest found that influenza viruses have mucinase, this mucinase on the surface of red blood cells and other cells of the animal protein affinity, so that’s why named “myxovirs”.
According to the antigenicity of nucleocapside protein and primary protein are different; it can be divided into A, B and C types:
Influenza A (Smith, 1933): worldwide pandemic, the most common, widely popular and belonging to zoonotic virus, a new variety of viruses due to irregular mutation of genes.
Influenza B (Francis, 1940): local outbreak, occasionally popular, with a better symptom than A.
Influenza C (Taylor, 1947): mainly aimed at infants and young children, and in sporadic cases.
Influenza is one of the major public health problems of all mankind, and it is prone to mutating and infectious, which often causes a worldwide influenza pandemic.
During flu season, to avoid cross infection when taking temperature, it is recommended to use the disposable temperature probe to monitoring the patient temperature.
