Diseases Caused By Insects And Their Symptoms

Pesky pests such as mosquitoes, fleas, bed bugs, ticks, and lice can transmit many diseases caused by viruses like yellow fever, chikungunya virus, dengue fever, etc.  Also bacteria such as plague and lime disease and parasites like sleeping sickness, malaria, filariasis, and leishmaniasis.  Moreover, these diseases are common in tropical environments, and malaria is the most common problem.

The Vectors (carriers of these diseases)

Bedbugs

Bed bugs also known as the Reduviidae, or triatomines are common on the South American continent. They are responsible for transmitting American trypanosomiasis (Chagas disease). They live in walls of damp houses, beds, etc. and they usually come out at night to feed on unsuspected sleeping tenants or homeowners.

Flies and midges

Horse flies (Chrysops) are vectors for filariasis, loa-loa, black flies transmits onchocerciasis, sand flies (phlebotominae) transmit leishmaniasis, and tsetse flies, which is a member of the glossina genus family are the vectors for African trypanosomiasis (sleeping sickness). Unfortunately, the bites are not usually felt, which makes it difficult to take immediate treatment.

Apart from transmitting microorganisms, these flies can cause conditions linked to the development and migration of the larvae beneath the skin. Furthermore, the Cayor worm is connected to the passage through the skin of larvae of Condylobia anthropophagi, which lay eggs on the ground, and linen.

The contamination happens by lying on the ground already contaminated by eggs laid by they laid by the fly or through clothes on which the flies have contaminated with their eggs. Dogs are prone to this disease because they roll over on the ground during playtime.

You can prevent it by not lying on the ground and avoid drying clothes in the open air. Also, it is advisable to iron clothes after they are washed to kill the larvae in the clothes. Another way of getting rid of these eggs is to hire a professional pest control operator.

Lice & fleas

These vectors transmit different bacterial infections such s trench fever (bartonellosis), relapsing fever (borreliosis) and rickettsiosis (typhus). Also, rat fleas transmit a disease called plague.

Mosquitoes

There are more than three thousand, five hundred (3,500) different species in the world, and about one hundred and seventy-five species are found in the United States. However, the three common species are the Anopheles, Aedes, and Culex; these species thrive in different habitats, times. They have different times when they are active, and types of bite.

Furthermore, mosquitoes lay and hatch their eggs in stagnant water such as lakes, receptacles, reservoir, and ponds to name a few. The type of diseases they transmit determines the specific species, climate, and habitat. Anopheles transmits malaria, dengue fever, chikungunya virus, yellow fever, lymphatic filariasis, and Japanese encephalitis. Mosquitoes’ bites are not usually painful, but they cause us to itch, and scratch and half of the mosquito bites occur through clothing.

Ticks

Like mosquitoes, ticks have different species, and each species have a relatively specific habitat. They transmit diseases such as the tick-borne spotted fevers, tick-borne relapsing fever, Q fever, tick-borne meningoencephalitis, babesiosis, ehrlichiosis, Crimean–Congo hemorrhagic fever, tularemia, and Lyme disease.

As soon as the ticks are on the skin, they move towards skin folds like armpits and groins. In the case of animals, they migrate to the ears, in between paws, and other hidden parts of their body. Unlike the other vectors, tick bites can cause a local inflammation reaction. However, ticks do not feed until 12 to 24 hours after implanting themselves on the skin, the risk of infection is low when you remove them quickly.

To avoid contracting these diseases, get rid of the vectors from your home and environment as soon as possible.
