I. Infection of diseases has been a major threat to human health, from historically large-scale infectious diseases such as black death and smallpox to today ‘ s new coronary virus pneumonia and influenza, which have had a profound impact on human life and socio-economic development. As the medical sciences continue to advance, research into common infectious diseases continues to deepen and treatments continue to be innovative and improved.
1. Respiratory infections • Influenza: caused by influenza viruses and characterized by seasonal epidemics. Symptoms include high heat, cough, headache, muscle pain, etc. Pneumonia: It can be caused by a variety of pathogens such as bacteria, viruses, fungi, common symptoms such as cough, cough, fever, respiratory difficulties, etc. 2. gastrointestinal infections • Bacteria dysentery: caused by dysentery bacterium, with major symptoms of abdominal pain, diarrhoea, mucous sepsis, etc. • Virusic gastrointestinal inflammation: caused by rotor viruses, and non-viruses, in the form of vomiting, diarrhoea, abdominal pain, etc. Sexually Transmitted Infections (STIs) AIDS: Caused by Human Immunodeficiency Virus (HIV), mainly through sexual contact, blood and mother-to-child transmission. It can cause damage to the human immune system, causing various opportunistic infections and tumours. Syphilis: Caused by a syphilis spiral that can be transmitted through sexual contact, mother-to-child transmission and blood. Symptoms are complex and varied and can be drawn into multiple organ systems. 4. Skin infection — sepsis: caused by golden sepsis or type B soluble streptococcus, in the form of skin sepsis, sepsis, etc. • Herpes: due to a pox-band herpes virus, the main symptoms are painful rashes, distributed along the nerves.
1. Pathogen research • With the development of molecular biology techniques, the study of pathogens affected by diseases has become more intensive. Scientists are able to quickly and accurately identify pathogen types, subtypes and variations, providing an important basis for disease diagnosis and treatment. • With regard to the emergence of new pathogens, such as new coronary viruses, global scientists are rapidly undertaking research to analyse the structure of the virus, its means of transmission and the mechanism for causing it, providing a scientific basis for the development of preventive and control measures. • In-depth study of the immune mechanism for infectious diseases, which helps to understand the human defence against pathogens and the development of the disease. For example, studies have found that T-cells and B-cells play an important role in the fight against viral infections, while immuno-modified imbalances can lead to an increase in disease. For some chronic infectious diseases such as AIDS, researchers are committed to exploring ways to improve the immune function and treatment effectiveness of patients. Epidemiological research • The prevalence trends, risk factors and transmission patterns of infectious diseases can be understood through large-scale epidemiological surveys and monitoring. This has helped to develop effective prevention and control strategies to reduce the spread of disease. • Use big data and information technologies to improve the timeliness and accuracy of surveillance and early warning of infectious diseases and to respond quickly to changes in the epidemic.
1. Drug treatment With the emergence of drug-resistant bacteria, the development of new antibiotics has become a priority. At the same time, the rational use of antibiotics and the avoidance of abuse are important measures to control the production of resistant bacteria. • Antiviral drugs: There are many options available for different types of viral infections. Examples include the anti-influenza drug Ostawe, the anti-HIV drug antiretroviral therapy (ART). The development of new antivirals, such as those for new coronary viruses, is also advancing. • Anti-fist drugs: The variety of anti-fist drugs is also increasing for fungi infections. However, fungi resistance is also growing and requires increased research and management. Immunization — Vaccines: Vaccines are one of the most effective means of preventing infection. In recent years, significant progress has been made in the development of new vaccines, such as the mRNA vaccine and the recombinant protein vaccine. These vaccines are efficient and safe and offer new options for preventing infectious diseases. • Immunomodifiers: For patients with low immune functions, such as AIDS patients and older persons, the use of Immunomodifiers enhances the immune function of the body and increases the resistance to infection. 3. Support for treatment • Support for treatment for people with severe infections is essential. Respiratory support, cycling support, nutritional support, etc. can help patients through periods of risk and increase the rate of cure. Rehabilitation treatment: Patients with an infectious disease need rehabilitation treatment during the rehabilitation period in order to restore their physical functioning and improve their quality of life. Rehabilitation treatment includes physiotherapy, occupational therapy, psychotherapy, etc.
Conclusion. The threat to human health posed by common infectious diseases remains, but as medical science progresses, there has been significant progress in the research and treatment of these diseases. From research on pathogens to the exploration of immunization mechanisms, from drug to immunotherapy and support for treatment, innovative methods and techniques provide us with a powerful weapon to fight infectious diseases. However, we cannot afford to remain light, and there is still a need to continue to strengthen research to improve disease prevention and control and to protect human health. At the same time, the public should increase its awareness of self-protection, develop good habits and participate actively in preventive measures, such as vaccinations, in order to meet the challenge of infection.
