Allergic asthma infection is the first.
In the explanation of allergic asthma, it shows that chronic respiratory inflammation is caused by mast cells, eosinophils, T lymphocytes and other cells, and when pollen and other allergens are diffused, the inflammation in susceptible people evolves into recurrent shortness of breath, wheezing, cough, chest tightness and other reactions. It shows that when there are more allergens, the respiratory tract with inflammation has an increased response to allergens and can be characterized as allergic asthma.
Allergic asthma
So it is because the color of the respiratory tract is very sad about the infection, and then allergic asthma occurs in response to allergen stimulation. In terms of the characteristics of the disease, the manifestation of allergic asthma, severe attacks are mainly at night and in the early hours of the morning. The incidence of allergic asthma in China is 3%, and the overall prevalence rate is 1%. There are about 10 million patients with allergic asthma in China, and there are about 100 million patients with allergic asthma worldwide.
In fact, the emergence of T lymphocytes and other immunoglobulins in the respiratory tract is also due to the invasion of bacteria or viruses and mycoplasma, which damages the respiratory tract, resulting in infectious inflammation in the respiratory tract. If breastfeeding infants are more likely to develop asthma after being infected by respiratory viruses. Because of the existence of many factors such as infection, inflammation and allergen, it is difficult to cure and easy to have repeated attacks, and recovery must be achieved in the initial period of systematic and long-term treatment.
Allergic asthma attack
Allergic asthma also has the difference between primary and secondary, as mentioned above, which refers to the development or complication of a variety of chronic respiratory diseases such as allergic rhinitis and chronic tracheitis. In general, it is not the more serious allergic asthma, such as aging and senility. Systematic treatment can lead to and control the disease.
