Myasis is a medical term used to describe a condition characterized by the infestation of living animals, including humans, by fly larvae. Commonly known as fly strike, it occurs when flies lay their eggs on or near the skin or open wounds of the host, which later hatch into larvae and feed on the tissue, causing irritation and potential health complications. These flies include various species such as blowflies, botflies, and screwworms.
The symptoms of myasis depend on the site and extent of infestation, but can include itching, pain, swelling, and the presence of crawling or visible worms. If left untreated, it can lead to secondary infections, tissue damage, and in severe cases, even death.
Myasis can occur in various parts of the body, including the skin, ears, eyes, nose, and genital region. The risk factors for myasis include poor hygiene, living in or visiting areas with high fly populations, poor wound care, and certain medical conditions that impair mobility or the body's natural defenses against infestations.
Treatment for myasis typically involves the removal of the larvae, which can be done through manual extraction, application of topical medications, or surgical intervention in more severe cases. Additionally, addressing the underlying cause, such as wound management or improving hygiene, is crucial to prevent reinfection.
Prevention strategies include maintaining good personal hygiene, keeping living spaces clean, covering wounds properly, using insect repellents, and avoiding areas with high fly activity.
