Medical importance:

Musca sp. is recognized as a potent mechanical vector due to its ability to carry a wide range of pathogenic microbes, including those responsible for typhoid, cholera, dysentery, and tuberculosis, on its appendages and body surfaces. Pathogenic microorganisms are transferred when contaminated body surfaces, feces, or regurgitated materials of the fly come into contact with human food and environments. The presence and activity of houseflies in unsanitary conditions facilitates disease outbreaks.
