The most important insects from medical point of view are the blood suckers or the insectborne diseases. Still others, almost non-blood suckers, but may attack man and animal to deposit their eggs or larvae of myiasis producing flies in skin, nose, eye, lung, ear, anus, vagina, and oral cavity as well as accidental gastrointestinal ones causing pathogenic condition known as myiasis causing different pathogenic conditions. Nosocomial myiasis must be noted carefully,
especially in case of hospitalized patients. Myiasis is a real welfare problem and many myiasis producers are zoonotic parasites. The nosocomial myiasis illustrates an unusual problem that may confront those responsible for infection control programs. However, still little is known about such an important subject in Egypt. This review would assist in designing appropriate prevention protocols and devising suitable control strategies to overcome zoonotic and nosocomial
myiasis and alleviate the economic losses.
