Promotion of vector organisms
1. What is a vector organism?
Vector organisms refer to organisms that can directly or indirectly transmit diseases (generally referring to human diseases) and pose a threat to human health.

Vector borne infectious diseases have the characteristics of rapid transmission and easy spread, posing a serious threat to people's physical health. With global climate change, accelerated urbanization, rapid development of tourism and trade, and continuous changes in the ecological environment, there have been new changes in the types, density, and distribution of vector borne diseases. Not only have the scope, frequency, and intensity of existing vector borne infectious diseases expanded, but some new vector borne infectious diseases continue to emerge.

What are the hazards of vector borne organisms?
Vector borne diseases include malaria, Japanese encephalitis, dengue fever, Zika virus disease, filariasis, pestis, hemorrhagic fever, fever with thrombocytopenia syndrome, allergy, etc. In addition to spreading diseases, vector organisms can also affect people's quality of life, harm industrial and agricultural production, and cause huge economic losses.

How should vector organisms be prevented and controlled?

Vector control should follow the principle of comprehensive control, focusing on the treatment of breeding grounds, supplemented by physical, chemical and other control measures, to control the density of vector organisms at a level that is not harmful enough.

Environmental management focused on breeding ground treatment is the fundamental measure for vector control. Based on this, one or more physical control measures such as instrument killing, chemical control measures such as insecticides/rodenticides, or biological control measures such as insecticides/rodenticides are selected according to the time and place. This can quickly reduce the density of vector organisms and control it at a lower level for a longer period of time.
