Myiasis  Is
the infestation of bodily tissues by the larvae of flying insects?
In Africa the tumbu fly and Lund's fly are responsible. Tumbu
flies
like to lay eggs on drying laundry and the larvae enter the skin
when clothes are worn. Human botfly affects people and cattle. A botfly catches blood-feeding insect, lays eggs into it and that insect later injects the eggs into the human when it feeds. These larvae usually stay where they penetrated. After 12 weeks the larvae leave the skin and mature in soil. New
world screwworm flies lay eggs on the edges of wounds and healthy
mucous membranes (mouth or nose) and the larvae then burrow in
and incubate about 1 week. Symptoms are mainly itchy sores or oozing boils, but there are no long-term effects. Sometimes maggots are seen by their air hole they create in the skin. Closing
the hole with Vaseline forces it closer to the surface, making
extraction easier. |
