Insects make up 85% of all living organisms on the face of the earth. They are represented by mosquitoes, ticks, lice, fleas, flies, ants, gnats, bees, wasps, moths, etc.
While some insect bites cause only a slight irritation or inflammation of the skin (ants, lice) or an allergic reaction (spider, wasp, or bee sting), some insects can transmit severe, potentially fatal diseases.
Mosquitoes can spread malaria, yellow fever, as well as dengue fever and lymphatic filariasis. Ticks, fleas, and flies can spread other diseases.
An insect bite carries the risk of infection from the insect’s contaminated saliva. This saliva may contain an infectious virus, bacteria, or parasite.
