Modern influenza, new coronary viruses, diseases caused by pathogens, not only threaten the health of individuals, but also, at some point, have a huge impact on the stability and development of societies. Therefore, a better understanding of infectious diseases and knowledge of their prevention and control are essential for the safety of individuals and public health.
1. The basic concept of infectious diseases: infectious diseases, by definition, are a series of pathological processes caused by the intrusion of various pathogens (such as bacteria, viruses, fungi, parasites, etc.). These pathogens enter the human body through different routes (e.g. respiratory, digestive, skin wounds, etc.), using the nutrients of the human body for reproductive purposes, while producing toxins or directly destroying the cell structure, resulting in impairment of the functioning of the organism and symptoms of heat, pain, inflammation, etc. Means of transmission of infectious diseases: The transmission of infectious diseases takes place in a variety of ways, including, inter alia, direct contact with the disease, such as through handshakes, hugs and kisses. Indirect exposure to transmissible cyanide: infection by exposure to objects contaminated by pathogens (e.g. doorknobs, utensils) before exposure to perceptible parts of their mouth, nose, eyes, etc. Air-transmission: Pathogens are transmitted through air flu, dust, etc. Food and water: The consumption of food contaminated with pathogens or the consumption of unclean water can cause infections such as cholera, typhoid, etc. Biotransmission: Certain pathogens need to be transmitted to humans through biological agents such as insects, animals, such as mosquitoes, and daphnia.
Prevention and control of infectious diseases: The key to preventing infectious diseases lies in cutting off transmission routes and protecting vulnerable populations. Specific measures include: hand washing, masking, vomiting and indoor ventilation, among other good practices, are effective ways of preventing respiratory diseases. In the case of digestive tract diseases, care should be taken to keep the diet healthy and to avoid the consumption of raw, cold and unclean food. Vaccination: Vaccination is an important means of preventing specific infectious diseases. Vaccination can stimulate the body to become immune, thereby reducing morbidity or symptoms in contact with pathogens. Cleaning and disinfection of the environment: regular clean-up of the living and working environment, decontamination of articles that may be contaminated with pathogens can effectively reduce the transmission of pathogens. Health surveillance and isolation: During the epidemic, the monitoring of the health status of individuals should be strengthened, and as soon as suspected symptoms are detected, medical treatment and appropriate isolation measures should be taken to prevent the spread of the disease. Public education and awareness-raising: increasing public awareness of infectious diseases and knowledge of prevention are important ways to control the spread of the disease.
3. Analysis of cases of specific infectious diseases: In the case of new coronary virus pneumonia, an acute respiratory infection caused by a new type of coronary virus. Since its first discovery, there has been a rapid global spread that has had a significant impact on global economic and social life. The new coronary virus is transmitted mainly through foaming and exposure, and is widely felt by the population. The key to the prevention of new coronary pneumonia is personal protection, such as wearing masks, maintaining social distance, washing hands, etc. At the same time, increased vaccination and increased immunity of the population are important means of controlling the epidemic. In summary, infectious diseases are one of the major factors threatening human health.
We can better protect ourselves and others from the disease by better understanding the means of transmission of infectious diseases, preventive measures and case analysis of specific diseases. In the days ahead, let us work together to build a healthier and safer environment.
