Diseases caused by pathogenic microorganisms invading the respiratory tract and reproducing are called respiratory tract infections. According to its location, it is divided into upper respiratory tract infection and lower respiratory tract infection. The former includes rhinitis, pharyngitis and laryngitis; the latter includes tracheitis, bronchitis and pneumonia.
What are the causes of respiratory infections?
Respiratory tract infections are infectious diseases caused by a variety of microorganisms including bacteria, viruses, mycoplasma, fungi, and parasites.
Upper respiratory tract infections:
About 90% are caused by viruses, and bacterial infections often follow viral infections. The disease can occur in four seasons and at any age, and it is spread through virus-containing droplets, mist, or contaminated equipment. Often when the body’s resistance is reduced, such as cold, fatigue, rain, etc., viruses or/and bacteria that have existed or invaded from the outside world quickly grow and multiply, leading to infection. The prognosis of the disease is good, self-limiting, and usually healed in 5-7 days. Often secondary to bronchitis, pneumonia, paranasal sinusitis, a small number of people can be complicated by acute myocarditis, nephritis, rheumatic fever and so on.
Lower respiratory tract infections:
There are more and more clinically available antibiotics, and drug-resistant strains have also increased significantly. Due to the application of high-dose cephalosporins, nosocomial infections, especially Pseudomonas aeruginosa and Enterococcus infections, are increasing. Whether it is a lower respiratory tract infection or an upper respiratory tract infection, most of it is caused by a virus, which is called a viral respiratory infection.
Viral infections are acute respiratory infections caused by a variety of viruses.
There are viral upper respiratory tract infections and viral lower respiratory tract infections. The former manifests as common cold, acute pharyngitis, tonsillitis, and laryngitis, and the latter manifests as tracheobronchitis and pneumonia. The incidence of this type of disease is high, and the population is generally susceptible to infection. Children, the elderly, malnourished and chronically ill people are more susceptible to the disease. The incidence is more frequent in winter and spring.

Respiratory tract infections are generally manifested as infections of the throat, nasal mucosa, and nasal cavity. The main manifestations are cough, sputum, sneezing, runny nose, fever, etc., as well as some symptoms of sore throat. In severe cases, if the throat appears The edema of the patient may affect our breathing, and may even develop to the vocal cords and may also cause symptoms such as vocal cord edema and hoarseness.
How to prevent respiratory infections?
1. Drinking boiled water often, the climate is dry in winter, and the human body is prone to lack of water. Drinking boiled water often can not only ensure the needs of the body, but also have the effect of diuresis, detoxification and elimination of waste.
2. Take care to avoid cold in summer and avoid physical decline.
3. Strengthen physical exercise and enhance physical fitness. Go outdoors and breathe fresh air.
4. Get more rest and adequate sleep can ensure the recovery of mental and physical strength, and at the same time ensure the improvement of immunity.
5. Do not smoke or smoke second-hand smoke, and do not stay for a long time in places with poor air quality and densely populated places to prevent infection.
6. Keep indoor air fresh and strengthen indoor ventilation.
