They are caled the vectors or the method of transmission.yhe mosquito itself does not become infected but acts as a carrier and transmits the infection to humans after biting the person
Vectors are living organisms that can transmit disease to humans. They can carry pathogens such as viruses, bacteria, or parasites, and introduce them to humans through bites or contact. Common vectors include mosquitoes, ticks, and fleas, which can spread diseases like malaria, dengue fever, Lyme disease, and bubonic plague. Vector control is an important strategy in preventing the spread of these diseases.
what is the role of a vector in the spread of a disease
In relation to malaria, the word 'vector' refers to the means by which a disease is transmitted, specifically an organic host. So bats, rats, ticks, fleas and Outbreak monkeys can all be vectors. In malaria's case, the vector is the mosquito. So you don't really use vectors to control malaria, but rather try to control malaria by stopping on the vector, i.e. get yourself a mosquito net or don't trek through the jungle.
A person or an animal has a blood borne disease such as malaria or yellow fever. For that disease to get to another person, it has to move to the other person's blood stream. How will it do it? A cold infects your nose. When you sneeze, someone else breathes that air and catches your cold. Flu infects your throat. When you cough, someone else breaches that air and catches your flu. People do not normally breathe your blood. There is a little animal called a female mosquito that eats your blood. Then it eats someone else's blood. Now if you have a blood borne disease it will go into the mosquito when it eats your blood. Malaria then becomes part of the mosquitoes saliva. Its saliva acts like drilling fluid. The mosquito uses it to drill through your skin. (Oil field workers use drilling fluid to drill oil wells.) The disease gets into the new person. The vector was the item, in this case the animal or mosquito that carried the disease from one person to the other.
Entomologists typically study mosquitoes, focusing on their biology, behavior, and role in spreading diseases like malaria and Zika. This field of research is crucial for developing effective strategies to control mosquito populations and prevent the spread of diseases they transmit.
A vector in Biology is a carrier /transporter of a virus fungi or bacteria. For example a plasmid is a vector that carries genetic information to a cell, and the mosquito is the vector of the malaria causing parasite.
Vectors play very important role in spread of many diseases. The microorganism spends dominant or recessive stage of it's life cycle. Without the vector the disease can not spread in most of the cases. Malaria and plague are two important vector born diseases.
The difference is that a vector merely transports the disease and will not have any traces of the disease in its immune system. A carrier will have the infectious agent but will not show symptoms of it. Both can transmit the disease to other organisms. Ex: carrier- human with HIV but not AIDS; vector- mosquito with malaria.
In the 1700s, malaria was primarily treated with the use of cinchona bark, which contains quinine, a natural antimalarial compound. This bark was often brewed into a tonic, and its use became more widespread after its discovery by Europeans in South America. Other treatments included bloodletting and herbal remedies, although these were largely ineffective. Preventative measures, such as draining stagnant water and avoiding mosquito-infested areas, were also recommended, although the role of mosquitoes in transmitting malaria was not understood at the time.
A vector is an organism, typically an insect or rodent, that can carry and transmit disease-causing agents such as viruses or bacteria into a host cell. Vectors play a crucial role in the transmission of diseases like malaria, dengue fever, and Lyme disease.
