Insect bites are painful enough, but they have a more unpleasant property. Many insects are carriers of dangerous diseases, some of which cause irreversible damage to the body.
The tsetse fly is a carrier of sleeping sickness
The tsetse fly is a real scourge of the African continent. Many individuals are infected with trypanosome parasites, which cause a dangerous disease - sleeping sickness. The initial period of the disease is quite harmless - the temperature rises and the lymph nodes swell. Often, the infected do not pay attention to these signs. This condition can even last for several years. In the next stage, parasites penetrate deep into the body, affecting the nervous system. The patient develops confusion, personality change, change of biorhythms. If urgent treatment is not taken, the person dies.
In recent years, the World Health Association has taken massive measures to treat sleeping sickness. The incidence has decreased by several percent.
Triatom bugs - a problem in Latin America
Triatom bugs are also carriers of the parasites that cause Chagas disease. These insects are common only in Latin America, Mexico is the most affected. The first symptoms of this disease are similar to the common cold. Sometimes in patients the site of the bug bite swells and skin changes appear - shagomas. In the next stage, microorganisms attack the heart or digestive tract. Because of these disorders, the patient gradually dies. At the moment, there are no effective drugs for the disease.
Anopheles mosquito - a carrier of a serious illness
Malaria mosquitoes are ubiquitous. Previously, they were a real scourge for humanity - hundreds of people died from malaria. Now there are drugs against this disease, but the severe stages of the disease bring irreparable harm to the internal organs. The malaria mosquito differs from the usual in longer limbs and specks on the wings. It is a carrier of the malarial plasmodium, a microorganism that lives in the blood and internal organs of a person. With the disease, the liver and spleen are affected, and anemia may also occur.
Larger, long-legged mosquitoes are often mistakenly referred to as malaria mosquitoes.
Horsefly - Causes Allergies and Diseases
Horsefly bite itself is quite unpleasant, but it can also cause many diseases. Horsefly is a carrier of tularemia, anthrax, filariasis. These diseases are very serious and cause severe damage to the internal organs. In addition, horsefly saliva itself contains toxins and anticoagulants that prevent blood clotting. Because of this, a very severe allergy can develop to bites, expressed in dermatitis, fever and abscesses.
