Paglalarawan

This 1920s photograph, taken somewhere in the southern United States, showed workers practicing “vector control” by digging a drainage ditch, in order to help disperse standing water that was acting as a popular breeding ground for a population of Anopheles mosquitoes, a well known vector for the parasitic disease, malaria.

Vector control aims to decrease contacts between humans and vectors of human disease. Control of mosquitoes may prevent malaria as well as several other mosquito-borne diseases such as West Nile virus (WNV), St. Louise encephalitis (SLE), and Dengue fever.
