How Chagas disease is transmitted
Not all bugs of the genus Triatoma are infested with trypanosome. But if the person is bitten by an infected bug, surely will contract the disease.
Trypanosome is a parasite that comes to healthy bug after it foundered animals (wild or domestic) or human trypanosome infected. When this occurs, the parasite multiplies in the intestine of the bug. Therefore, when an infected bug bites a healthy person, it will not take the parasite in the blood. But when defecating near the wound, it will stop trypanosomes with feces, which will come into contact with the wound for involuntary scratching, penetrating the blood of the person.
When the parasite reaches the human blood, the first thing it does is infect striated muscle fibers in different locations, or phagocytes (immune cells whose main function is to remove bacterial debris, accessories antigen-antibody and other waste). They begin to multiply inside muscle cells or the phagocyte, going through different stages of evolution, so that the cell can not accommodate more parasites and breaks.
The parasites are spread by blood, but can infect other cells, since only within them can multiply.
When a bedbug bites an infected person, blood takes with free parasites and the cycle begins again by biting into a different person.
