                  Pathogenesis, Diagnosis, and treatment of Malaria Malaria : -  A mosquito-borne infectious disease caused by the bite of a mosquito that carries the parasitic protozoa called Plasmodium species - The disease can be fatal and life-threatening for humans, transmitted to humans through the bite of infected female Anopheles mosquitoes. - Plasmodium species comes under the parasite group called "Sporozoa" - Malaria is one of the major zoonotic diseases that cause millions of human deaths each year - It is a major public health concern, especially in tropical and subtropical regions. More than 75% of deaths occur in the African region of the world, over a million people mostly children die from malaria each year worldwide Plasmodium species: - Malaria is a vector-borne infection that is spread through the bite of the mosquito, thus the term given for this type of infection is a 'zoonotic disease'. The infected...

Most important mosquito-borne microorganisms: Malaria Parasites (Plasmodium spp.): Malaria is a serious and potentially fatal disease caused by various species of the Plasmodium parasite. When an infected mosquito bites a person, it transfers the parasite into their bloodstream. The parasites then infect the liver and red blood cells, leading to symptoms like fever, chills, and anemia. Dengue Virus : Dengue fever is caused by the dengue virus, which is transmitted by Aedes mosquitoes, primarily Aedes aegypti. Dengue fever can cause a wide range of symptoms, from mild fever to severe dengue (also known as dengue hemorrhagic fever), which can be life-threatening. Zika Virus: Zika virus is another pathogen spread by Aedes mosquitoes. In most cases, Zika causes mild or asymptomatic infections, but it can pose serious risks to pregnant women due to the association with birth defects such as microcephaly in babies. Chikungunya Virus: Chikungunya is a viral disease transmitted by Aedes m...
