INFLUENZA

Introduction of influenza Influenza can be said to be generations of infectious diseases that we know suffer. The term influenza comes from the Latin "influentia" first used by Italians in the 1600s. It is a highly contagious characteristic of respiratory infections. In addition to our human beings, influenza also occurs in pigs, horses and several other mammals, and certain wild and bird species. When chicken influenza affects people in Hong Kong, it can also be observed from seeds at the end of 1997 from seed to species.

Cats can infect various influenza strains. Avian influenza is often called avian influenza, swine is used as swine flu, horses are used with equine influenza. Human influenza is often called seasonal influenza. Mizuzo is an important host for many influenza subtypes. The best way to prevent influenza in humans is to receive vaccination against influenza every year. Appropriate hygiene management is also important. When sneezing, cover your mouth and nose and wash your hand regularly to avoid contact with sick people. Wear protective clothing, gloves, masks when contacting pigs and birds that may be infected with influenza.

Influenza A virus can be divided into various strains. In the present situation, it is found in humans that subtypes of influenza A virus are influenza A (H1N1) and influenza A (H3N2) viruses. If we resemble the spring of 2009, the new H1N1 influenza virus seems to cause disease. At the time, this virus was very different from the spread of human influenza A (H1N1) virus. For about 40 years, this new virus caused the first influenza pandemic. This virus, commonly referred to as "2009 H1N1", was replaced by the H1N1 virus previously infected in humans.

In the spring of 2009, a new influenza A (H1N1) virus appeared. It was first discovered in the United States and spread quickly to the United States and the world. This new H1N1 virus contains a unique combination of influenza genes that has never been seen in animals or humans. This virus was named Influenza A (H1N1) pdm09 virus. There are few young people who have immunity against (H1N1) pdm09 virus, but nearly one third of people over the age of 60 have antibodies against this virus, perhaps it is It was because they were exposed to the older H1N1 virus earlier in their life. Since the (H1N1) pdm09 virus is very different from the now prevalent H1N1 virus, the seasonal influenza vaccine provides little cross protection against (H1N1) pdm09 virus infection. * The Centers for Disease Control and Prevention estimate that in the first year of virus infection, in 2009 from 151,700 to 575,400 people worldwide died of H1N1 infection.
