Myiasis is infection with a fly larva, usually occurring in tropical and subtropical areas. There are several ways for flies to transmit their larvae to people.
• Some flies attach their eggs to mosquitoes and wait for mosquitoes to bite people. Their larvae then enter these bites.
• Other flies' larvae burrow into skin. These fly larvae are known as screwworms. They can enter skin through people's bare feet when they walk through soil containing fly eggs or attach themselves to people's clothes and then burrow into their skin.
• Some flies deposit their larvae on or near a wound or sore, depositing eggs in sloughing-off dead tissue.
HOW IS MYIASIS DIAGNOSED?
As a rare condition, Myiasis is usually misdiagnosed. Intestinal myiasis and urinary myiasis are especially difficult to diagnose. Serologic testing is used by a general physician to diagnose the presence of botfly larvae in human.
HOW IS MYIASIS TREATED?
First treatment is prevention. It is important to educate people about eradication of adult flies and maintaining proper hygiene of wounds. The breathing hole of the cutaneous myiasis is first sealed using petroleum jelly to cover it. Lack of air forces larvae outside, from where they can be eliminated. Incisive removal of the larvae is more common for large infestations.
