I. Definition and classification of infectious diseases: Infectious diseases are processes that grow, reproduce, cause a series of tissue injuries and pathological reactions after the invasion of the human body by pathogens. These pathogens can be transmitted to humans by a variety of means, including air, water, food, exposure, etc. Depending on the mode of transmission, infectious diseases can be broadly classified as: e.g. flu, measles, pox, mumps, etc. These diseases are transmitted mainly by air-hot, with high rates of winter and spring. Infectious diseases in the digestive tract: bacterial dysentery, cholera, hepatitis A, etc. Pathogens are transmitted via the faeces and the disease is imported from the mouth. Exposure to infectious diseases such as parageny pneumonia, nonovirus infections, etc. Dissemination through direct or indirect contact (e.g., common articles). Epidemic diseases such as malaria, dengue fever, epidemic type B encephalitis, etc. It is transmitted by bites from vector organisms (e.g. mosquitoes, flies). Blood- and body-borne diseases: HIV, hepatitis B, etc. It is transmitted by body fluids such as blood, semen and vaginal secretions.
II. Common Infective Diseases and their Characteristics: Pandemic Influenza (Influenza) Phenomenon: Influenza virus, type A, B and C. Transmutation pathways: mainly by air foam and also indirectly by virally contaminated articles. Symptoms: fever, all-body sores, sores, cough, etc. Prevention: Inoculation against influenza is the most effective means of prevention, with attention to personal hygiene and the avoidance of mass-intensive sites/polytics: herpes virus. Transmissible routes: Exposure to virus-contaminated dust, clothing, appliances, etc., can also be transmitted, mainly through foam. Symptoms: headaches, discomfort, fever, followed by rashes, rashes, then drying up after 1-2 days. Prevention: Vaccination against pox and maintenance of good hygiene practices. Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia Pneumonia (a) The means of communication: they are transmitted mainly through foam, which makes children and the elderly vulnerable. Symptoms: Heating, coughing (mainly irritating dry cough), headaches, aldicarb, ingesting, etc. (b) Prevention: maintaining good hygiene practices, avoiding exposure to pathogens and, if necessary, vaccinations. The virus is infected with the pyropathogen: the virus is genetically diverse and highly variable. (b) The means of transmission: exposure to the excreta and vomiting of patients, meals with infected persons, etc. Symptoms: Diarrhoea, vomiting, gastric aversion, nausea and stomach pain, with children mainly vomiting, and adults more diarrhoea. Prevention: strengthening hygiene and health management, ensuring water and food hygiene, regular cleaning and ventilation of public places. Tetra-tuberculosis pathogen: tuberculosis streptococcus. (b) The means of communication: foam, air and exposure. Symptoms: continued coughing, coughing, blood stinging, lack of strength, weight loss, etc. Prevention: Vaccination of BCG, maintenance of good hygiene practices and avoidance of close contact with tuberculosis patients.
III. Preventive measures against infectious diseases: personal hygiene: hand-washing: hand-washing before eating, after returning from work and after exposure to public goods. Ventilation: Maintaining indoor air flow to avoid being confined for long periods of time. Sterilization: regularly disinfecting of homes and workplaces, in particular public contacts such as doorknobs, taps, etc. Avoid contact with pathogens and with humans or animals with infectious diseases and with their secretions and excreta. Avoid overcrowding in public places and avoid sharing personal belongings such as towels, utensils, etc. (b) Increased immunosuppressive diet: extra vegetables and fruits to ensure nutritional balance. Moderate exercise: Maintain a reasonable amount of movement and improve health. Adequate sleep: Ensuring adequate sleep, which contributes to physical recovery and increased immunity. Vaccination against influenza, New Crown Virus, pneumonia and pox can effectively prevent the occurrence of related infectious diseases. Active vaccinations are carried out in accordance with the vaccination procedure, protecting the health of themselves and their families. When a medical doctor finds symptoms of an infectious disease in his or her own or family, he or she should be treated in a timely manner and in accordance with the doctor ‘ s treatment programme. (c) Take medication, rest and review on time in order to achieve early recovery.
Infective diseases are one of the types of diseases that we cannot avoid in our daily lives, but we can significantly reduce their incidence and risk of transmission by strengthening preventive measures such as personal hygiene, avoiding exposure to pathogens, increasing immunity, vaccinations and timely medical access. At the same time, all sectors of society should work together to focus on public health and contribute to a healthy and safe living environment. The fight against infectious diseases requires the participation and efforts of society as a whole, and let us work together to protect healthy homes.
