Which Insect carries a Sickness called Malaria – The protozoa are living, and unicellular eukaryotic organisms. Together with algae, they form the Protist Kingdom. These beings are important, for many cause disease to man. By knowing these organisms, we can better understand the treatment and prevention of these diseases.

Among the diseases caused by protozoa, we can mention malaria, amebiasis, Chagas diseases, giardiasis and visceral leishmaniasis.

The malaria is caused by the protozoan parasite called Plasmodium. In the USA, three species are related to this disease in humans: P. vivax, P. falciparum and P. malariae. This disease affects many people around the world every year, especially in tropical regions such as ours. According to the World Health Organization, estimates are that 40% of the world’s population is exposed to malaria and that more than 1 million die each year.

The malaria is transmitted through the bite of a mosquito of the genus Anopheles, but only the female transmits the disease. This mosquito is popularly known as mosquito-prego and carapanã. These mosquitoes have a nocturnal habit, so important preventive measures at bedtime, such as the use of mosquito nets and screens on the windows are important. In addition, it is necessary also the use of repellents, as well as the elimination of mosquito breeding sites.

The disease is characterized by high fever (39 to 40 ° C), chills, headache, abundant sweating, and vomiting. Its diagnosis is made through blood tests in which the presence of the parasite is verified.

The amebiasis is caused by the protozoan parasite Entamoeba histolytica. The infection occurs due to the ingestion of this protozoan together with water or food contaminated by feces. This infection can be asymptomatic or present severe diarrhea with the presence of blood. To avoid this disease, it is important to maintain personal hygiene, wash food well, drink filtered or boiled water, and especially treat the sick individual and invest in basic sanitation.

The giardiasis is transmitted by the protozoan parasite called Giardia lamblia (also known as Giardia lamblia ). Like amebiasis, this disease is contracted due to the ingestion of contaminated food and water. Giardiasis causes abdominal pain and a picture of diarrhea that can lead to dehydration and weight loss. To avoid transmission, investment in basic sanitation, treatment of patients and good hygiene habits are important.

The Chagas disease is a well – known disease caused by a protozoan parasite called Trypanosoma cruzi. Its transmission occurs mainly through triatomids, also called barbers, but can also occur by blood transfusion, during pregnancy, organ transplantation, etc. The disease can be asymptomatic in the first years, manifesting many years after the infection, and the organ most affected is the heart. To prevent disease, it is important to control the reproduction of the barber and protect the house with doors, screens, and windows. Barbers are usually found in cracks in mud houses, so investing in housing is also a prophylactic measure.

The visceral leishmaniasis is a disease transmitted by the protozoan parasite called Leishmania chagasi . The main form of transmission is the bite of an insect known as phlebotomid. The clinical diagnosis is complicated because the symptoms resemble those of other diseases. The main features are fever for a long period, increase in spleen, increase in liver, anemia, cough, diarrhea, among others. For prevention, it is necessary to fight the insect and treat the sick.
