Control and elimination of infectious diseases

spectrum of disease control
Because of their specific epidemic, characteristics and different external environment, various infectious diseases have great differences in their prevention goals. At present, most infectious diseases can only aim at controlling the incidence and prevention of epidemics. Very few diseases are effective because they are mature and can meet the elimination requirements. Very few diseases can achieve the goal of elimination under the premise of mature conditions and the concerted efforts of all countries in the world. The prevention of infectious diseases, from control to elimination to elimination of the differences in disease prevention strategies and measures, is called the spectrum of disease control. In order to prevent diseases and promote human health, people expect to gradually control the diseases that are currently difficult to control, and on this basis, they can move toward elimination, and finally achieve the goal of elimination. This process is not only a beautiful ideal of mankind, but also an extremely arduous process. To achieve this goal depends on scientific progress, including the progress of epidemiology and the preparation of relevant conditions.

Control and elimination of infectious diseases

Control refers to reducing the incidence and/or prevalence of the disease. Some diseases have obvious control effects. Once the countermeasures and measures are implemented, the incidence rate drops significantly, such as polio vaccine against polio, measles vaccine against measles, and improved drinking water supply for chronic water-type typhoid fever. There are also some diseases or due to the complex environment, or there are still no effective countermeasures and measures at this stage, so even if measures are taken, the effect is not obvious. There are still many diseases that fall into this category.
