Respiratory diseases

Respiratory diseases are also very common, mainly acute and chronic diseases of the upper and lower respiratory tract, inflammation, and respiratory allergy diseases. They are mainly caused by some tumors or other types of diseases. The main diseases affecting the upper respiratory tract include and, at the same time, the main diseases in the upper respiratory tract include tracheobronchitis, bronchiolitis, and tracheobronchial arteries, so treatment in daily life is also relatively critical.

Its main characteristics are that the lung capacity decreases, or the resistance involved is gradually increased. It is mainly caused by some diseases, mainly acute rhinitis, acute pharyngitis, acute tonsillitis, and some diseases caused by upper respiratory tract infections. Various viruses and bacteria also cause such diseases.

Acute upper respiratory tract infection (AUR1) is an inflammation of the upper respiratory tract caused by various pathogens, referred to as upper respiratory tract infection, commonly known as "cold", and is the most common disease in children. The disease mainly invades the nose, nasopharynx and pharynx. If the inflammation in a certain part of the upper respiratory tract is particularly prominent, it will be named according to the inflammation, such as acute rhinitis, acute pharyngitis, acute tonsillitis, etc. Acute upper respiratory tract infection is mainly used for patients with local upper respiratory tract infection whose location is not clear.

It can be caused by various viruses and bacteria, but more than 90% are viruses, mainly rhinovirus (RV), respiratory syncytial virus (RSV), influenza virus (FluV), parainfluenza virus (paraFluV), adenovirus (ADV), etc. Viral infection may be followed by bacterial infection, the most common of which is hemolytic streptococcus, followed by Streptococcus pneumoniae, Haemophilus influenzae, etc. Mycoplasma pneumoniae is also not uncommon.

Infants and young children are susceptible to this disease due to the anatomical and immune characteristics of the upper respiratory tract. Nutritional disorders, such as vitamin D deficiency rickets, subclinical vitamin A, zinc or iron deficiency, or improper care, climate change and adverse environmental factors, can easily lead to recurrent upper respiratory tract infections or prolong the course of the disease.

Respiratory diseases are more common in dry climates, and the incidence rate in the north is significantly higher than in the south. The dry climate can easily cause symptoms of heat in the human body, thus leading to respiratory infections.

The above are common diseases of respiratory tract infections. Respiratory diseases are mainly caused by the high temperature and dry climate. The main diseases caused are acute rhinitis, acute pharyngitis, acute tonsillitis and other diseases. Therefore, the incidence rate in the north is also relatively high. Due to different age, body structure and lesion site, the severity of the disease varies, so the use of medication is the key.
