Knowledge on respiratory infection prevention

The prevention of respiratory infections is an important element in ensuring personal and public health. The incidence of respiratory diseases and the risk of infection have increased significantly in recent years with environmental pollution, climate change and the emergence of new viruses. This paper will explore the prevention of respiratory infections from several angles and help readers better protect their health and that of their families.I. Common types of respiratory infectionsRespiratory system infections can be divided into upper and lower respiratory infections. Upper respiratory infections include, inter alia, nasal, osteoporosis, tonsilitis, common symptoms such as nasal plugs, running slugs and throat pains. Lower respiratory infections include bronchitis, pneumonia, etc. Symptoms may include cough, cough, respiratory difficulties, etc. New coronary virus pneumonia (COVID-19) is a disease of high concern in recent years.II. Channels of transmission of respiratory infectionsRespiratory infections are transmitted mainly by:Foam spread: A virus or bacteria hangs in the air by coughing, sneezing, etc., causing infection after inhalation by healthy people.Exposure spreading: Pathogens are attached to the surface of objects, and healthy people touch the mouth, nose, eye, etc., and cause infection.Air transport: Certain pathogens can be transported by air, such as tuberculosis.III. Methods to prevent respiratory infections1. Personal hygiene practicesMaintaining good hygiene practices is the basis for preventing respiratory infections. The following are specific recommendations:Hand-washing: hand-washing with soap and running water for at least 20 seconds, especially after exposure to public goods or patients. In the absence of water and soap, an alcohol-containing hand disinfectant can be used.Avoid touching of the face: avoid touching of the mouth, nose, eye, etc., with unclean hands to reduce the transmission of pathogens.Mask: In densely populated locations or high-risk areas, masking can effectively prevent the spread of foam.Coughing and sneezing: Covering with paper towels or elbows during coughing or sneezing, avoiding direct hand contact with the nose and mouth.2. Environmental decontaminationKeeping the environment clean and disinfecting is an important part of preventing respiratory infections. The following recommendations are made:Regular cleaning and disinfection of home environment: especially HF-exposed items such as doorknobs, switches, desktops, etc.Ventilation: Maintain indoor air flow, regular window ventilation, and reduce the concentration of pathogens in air.Use of air purifiers: In a closed environment, the use of air purifiers can effectively filter pathogens and particles in the air.3. Healthy diet and living habitsGood eating and living habits enhance immunity and reduce the risk of infection. The following recommendations are made:A balanced diet: Adequate proteins, vitamins and minerals, especially foods rich in vitamins C and D, such as citrus fruits and fish.Adequate sleep: Maintain regularity, ensure adequate daily sleep time and increase body immunity.Adequate exercise: Regular aerobics, such as running, swimming, etc., to enhance CPR function and immunity.Prohibition of alcohol: Smoking can seriously damage the respiratory system and increase the risk of infection. Overdrinking also reduces immunity.VaccinationVaccines are an effective means of preventing respiratory infections. The following are common vaccines:Influenza vaccine: Annual influenza vaccination can reduce the risk of influenza.Pneumococcal infections can be prevented in the case of pneumocococcal infections, as applied to the elderly and people with low immunity.New canopy: New canopy can effectively prevent new coronary virus infections and serious diseases.Avoiding exposure to sources of infection(b) Avoid, to the extent possible, travel to densely populated sites and reduce contact with infected persons during periods of high outbreak or influenza seasons. If necessary, personal protection, such as wearing masks and maintaining social distance, must be ensured.IV. Preventive measures for specific population groups1. Older personsOlder persons are less immune and at higher risk of infection. In addition to the above-mentioned preventive measures, periodic health examinations should be conducted to detect and treat potential respiratory diseases in a timely manner.2. ChildrenChildren ‘ s immune systems are not fully developed and are vulnerable to respiratory diseases. Parents should take care of their children ‘ s diet and wellness, avoid contact with infected persons and receive regular vaccinations.3. Groups with low immunityPeople with low levels of immunity, such as those living with AIDS, cancers receiving chemotherapy, should pay special attention to personal protection, avoiding exposure to the source of infection and receiving regular medical monitoring and treatment.V. Emergency treatment of respiratory infectionsDespite preventive measures, respiratory infections are still possible. The following are some of the urgent recommendations:Timely access to health care: In case of respiratory difficulties, high fever and severe coughing, immediate access should be provided to avoid delays in treatment.Rest and isolation: People infected should try to rest and avoid transmission, especially to their families and colleagues.Medicinal compliance: strictly in accordance with the doctor ‘ s instructions, avoiding the abuse of antibiotics.Water retention: Drink more water and keep the respiratory tract wet, helping to drain the sap.Concluding remarksThe prevention of respiratory infections requires a wide range of efforts, including hygiene practices, environmental disinfection, healthy diet and living habits, vaccinations, etc. Specialized groups such as the elderly, children and those with low levels of immunity should take stricter preventive measures. Through a scientific approach to prevention, we can effectively reduce the risk of respiratory infections and safeguard individual and public health. It is hoped that the content of this paper will be useful to readers and that we will be able to protect our breathing well.
