According to a report from New York's Western Front flu - London, the German army legs were closed. Although influenza is spreading to us, the main doctor thinks that illness is not so common as it is most likely to spread under unhealthy conditions. Caesar is looking for them to start a proper attack on our strong minds as the German army reports that the proportion of influenza to the hospital is increasing.
In Northern Europe, Southern Europe, Western Europe, influenza increases are seen in many countries, influenza B is predominant, but the main subtype of influenza A varies from country to country. In type A assay, the number of A (H1N1) pdm09 virus exceeded A (H3N2) virus. Until now it has been widely believed that influenza B infection is milder than influenza A, but studies have shown that influenza B virus may be as severe as influenza A virus It is.
Influenza is one of the most important acute upper respiratory tract infections. Influenza virus causes extensive respiratory diseases and brings significant morbidity and mortality to children. Influenza virus causes epidemic diseases (influenza A and B virus) and sporadic disease (type C) in humans. Seasonal human influenza causes approximately 36,000 deaths and 226,000 hospitalizations annually in the United States. In addition to humans, influenza may infect various animals. Some of these influenza strains are species-specific, but new influenza strains may infect humans from other animal species (see Pathophysiology). The term avian influenza used in this context refers to a human to animal infection with a human influenza virus strain that mainly affects birds.
This genus is influenza B virus. Influenza B virus is almost completely infected with humans and is not as common as influenza A virus. Other animals known to be susceptible to type B influenza virus are only seals and ferrets. Because this type of influenza mutates at a rate 2-3 times slower than type A, there is less genetic diversity, there is only one type B serotype. Due to the lack of diversity of antigens, immunity against influenza B usually comes early. However, mutants of influenza B virus are sufficient to cause persistent immunity. This rate of antigenic change, coupled with its limited host range (suppression of cross-species antigenic change), ensures that the global epidemic of influenza B does not occur
Influenza virus sometimes experiences major changes and no one has immunity. When this happens, a large number of people of all ages around the world will get influenza within a few months. This is called "pandemic" of influenza. The epidemic occurred in 1889, 1918, 1957 and 1968. Experts are working hard to prevent pandemic in the next big change of influenza virus. The influenza virus is in the nose and throat. As children often touch the nose, eyes and mouth, packing things in their mouths and touching each other while playing, Haemophilus influenza is easy to spread. There are also many contacts between parents and carers and children.
