What viruses cause viral bronchitis

Viral infection, such as a viral cold, that is, influenza, is one of the causes of viral pneumonia and bronchitis. Viral infection of the upper respiratory tract inflammation, are easy to cause viral bronchitis and other lung inflammation. Specific viruses include respiratory influenza virus, parainfluenza virus, and syncytial virus, coronavirus, rhinovirus, adenovirus and so on, among which influenza virus is the most likely to cause viral bronchitis or viral pneumonia.

Influenza virus is a very stubborn kind of virus, so it can become epidemic, contagious and aggressive. And it will accelerate the development of the disease with the help of a sudden drop in temperature, vasoconstriction of the respiratory tract, and even spasm, and a decline in defense function, so after the onset of the flu, children and young people will have a high fever in a short period of time. It is also easy to change into viral bronchitis or pneumonia within two or three days.

Influenza virus

Respiratory syncytial virus, also known as PNA virus, belongs to the paramyxoviridae family. It is most vulnerable to infantile transmission and infection through air droplets and close contact, with an incubation period of up to 7 days. After invading the human body with viral bronchitis, the symptoms are also the strongest in infants and young children. The initial stage is high fever, rhinitis and other upper respiratory tract inflammation, and then will quickly turn into viral bronchitis or pneumonia, some infants and children are also easy to be complicated with otitis media, pleurisy, myocarditis and so on.

The coronavirus of the coronavirus family has been found to have 15 different coronaviruses, most of which cause disease in general mammals and birds, while a few cause disease in humans. After people are infected with coronavirus, they are mostly caused by respiratory inflammation and are prone to severe respiratory syndrome, such as SARS in 2003, that is, SARS, which is caused by the change of coronavirus. And this kind of virus is suitable to develop wantonly in the environment with high temperature, but it can restrain and eliminate rhinovirus.

Avian influenza virus

Up to now, 120 kinds of rhinovirus have been found, which can be said to be the virus with the largest number of serotypes among human viruses. after infection, people will initially develop upper respiratory tract inflammation such as colds, such as the common cold, most of which are caused by rhinovirus. and then the development will lead to viral bronchitis, pneumonia and other serious diseases. Moreover, rhinovirus exists all the year round, so about half of colds and viral bronchitis are caused by rhinovirus. Compared with rhinoviruses, adenoviruses attack the respiratory system, and people have little power to get viral bronchitis.
