Several Types of Insects Can Cause an Allergic Reaction in Humans

Several types of insects can cause an allergic reaction in humans. This is a common occurrence. These types of insects include ants, bees, wasps, spiders, mosquitoes, bed bugs, and mites. In fact, insects account for about 90 percent of animal life on earth.

These organisms are classified into 33 orders. The most common types are stinging insects, which include ants, bees, and wasps. These insects can cause severe allergic reactions, which include swelling of the skin, airways, and stomach. Some of these reactions are immediate, while others take days or weeks to develop.

Typical reactions after insect stings include swelling of the airways, rapid pulse, dizziness, and stomach cramps. Some species of ants and hornets can cause anaphylactic shock. Other types of insects, such as mosquitoes, rarely trigger IgE-mediated reactions.

Various species of insects are parasitic on humans. These parasites include bloodsucking insects, like bedbugs and fleas. These insects can cause a variety of diseases, including West Nile virus, dengue fever, and malaria.

Some species of lice can cause serious allergic reactions. These insects can infect the skin and scalp. They can also infect the groin. Infections can lead to scarring of the skin. These infestations are common in children. They can be hard to detect and treat because of the hidden character of these organisms.

These parasites are often transferred between individuals. These infections are often associated with poor sanitation and large numbers of people living in close quarters.
