Spring temperature changes, alternating between hot and cold, is conducive to the growth and reproduction of pathogens, the human body may be accidentally pathogenic microorganisms "take the opportunity to enter", after the start of school students close and frequent contact, greatly increasing the risk of transmission of infectious diseases, parents, schools, children can not relax. Let's learn about disease prevention measures.
Respiratory experts remind.
Respiratory infectious diseases are still in a high incidence period, and common respiratory pathogens such as influenza virus, new coronavirus, respiratory syncytial virus, adenovirus, and Mycoplasma pneumoniae can be detected, among which the new cases of new crown have increased slightly, and influenza is still the most important respiratory disease at present.

How to maintain good respiratory hygiene.
1. When coughing or sneezing, cover your mouth and nose with tissues, elbows, etc.;
2. Eat a balanced diet, exercise moderately, and ensure adequate rest;
3. Avoid close contact with patients with influenza-like symptoms (fever of 38°, with cough or sore throat);
4. During the influenza season, try to go to crowded places as much as possible;
5. Once flu symptoms appear, you should rest at home, conduct health observation, go to work and class without illness, and wear a mask when contacting family members to reduce the spread of diseases;
6. If the condition is progressively worsened, go to the hospital as soon as possible, and the patient and accompanying staff should wear masks to avoid cross-infection.
Respiratory diseases are closely linked to air pollution.
First of all, negative oxygen ions have the effect of dust removal and sterilization, which can remove indoor dust and infectious disease pathogens, which is an important way for the spread of respiratory infectious diseases. Negative oxygen ions eliminate indoor dust, which can cut off the spread of infectious diseases indoors. 
Secondly, negative oxygen ions can inhibit the growth of bacteria and viruses. The key book "Ecological Science", Vol. 18, No. 2, June 1999, reported that air negative oxygen ions can inhibit the growth of bacteria and viruses - the article pointed out that negative oxygen ions can reduce the mortality rate of mice infected with influenza virus, and can inhibit the growth of staphylococcus, streptosporum, cholera solitary bacteria and Salmonella bacteria.
Negative ions are how to prevent respiratory diseases.
Air negative oxygen ions can improve the respiratory tract prevention function: The respiratory tract has a strong defense function, each person can inhale 10,000 liters of air every day, which contains 1.5 billion bacteria, but there is no bacteria in the lungs, which is a great wall of the human body, negative oxygen ions are the solid backing of the Great Wall, and have the effect of promoting cell regeneration and protecting the Great Wall.
Air negative oxygen ions enhance airway ciliary movementForeign substances such as bacteria and viruses that have been mixed into the airways can be excreted from the body with the movement of cilia.
Air negative oxygen ions can enhance the activities of respiratory lysozyme and interferon, which has a bactericidal effect on some pathogens.
Air negative oxygen ions activate the "dust" cells in the lungsto transform them into macrophages and exert phagocytic functions.
Air negative oxygen ions can improve lung ventilation and ventilation, increase intracellular oxygen supply, enhance the body's ability to resist disease.
Negative oxygen ions in the air protect the cells of the alveolar parietal cells from being attacked by virusesBecause viruses must have a negative charge to attack biological cells, negative oxygen ions in the air make cells also have a negative charge, so that the virus loses its ability to attack cells.
Air negative oxygen ions can improve the body's immune functionEnhance the body's ability to resist disease and protect susceptible populations.
