Vector control is the practice of implementing various methods to control and prevent the spread of vector-borne diseases, which are diseases transmitted to humans by insects or other organisms. This can include the use of insecticides, environmental manipulation, and vaccination programs to reduce the population of vectors and limit their ability to transmit diseases. Vector control is an important component of public health efforts in many parts of the world where diseases such as malaria, dengue fever, and Zika virus are prevalent. By effectively controlling vectors, the spread of these diseases can be greatly reduced, improving the overall health and well-being of communities.
