Criteria for classifying influenza viruses into genera types and subtypes have been discussed with reference to the 6th report of ICTC. Influenza commonly known as the flu is an infectious disease caused by influenza viruses. Influenza type A viruses are RNA viruses categorized into subtypes based on the type of two proteins on the surface of the viral envelope.
Type B influenza can be just as severe as type A influenza but is less common throughout the flu season compared to. All known subtypes of influenza A viruses have been found among birds except subtype H17N10 and H18N11 which have only been found in bats. The formal taxonomic classification of viruses.
Type C influenza usually only causes mild respiratory infections. The hemagglutinin H and the neuraminidase N. Data mining and model-predicting a global disease reservoir for low-pathogenic Avian Influenza A in the wider pacific rim using big data sets.
Symptoms range from mild to severe and often include fever runny nose sore throat muscle pain headache coughing and fatigue. Virus classification is based mainly on characteristics of the viral particles including the capsid shape the type of nucleic acid DNA or RNA double stranded ds or single stranded ss within the capsid the proces s of replication their host organisms or the type of disease they cause. Highly pathogenic avian influenza HPAI or low pathogenic avian influenza LPAI.
Influenza types A B and C can cause illness in humans. For influenza A viruses differences in two viral surfaces glycoproteins hemagglutinin HA and neuraminidase NA permit categorization into different subtypes.
