Measles VirusIn the 1800s the morbilli was a very dangerous disease, and when people who come in contact with it go out die, if they have never been exposed to the virus before. The rubeola is transmitted done the air. The way that the virus is transmitted is that infected droplets be released by coughing, sneezing, and by talking. When the infected droplets that contain the rubeola are in the air, they are taken into the body through the mouth, nose and eyes of the potential person that could press the virus. People with low respiratory tract, which is the lungs and bronchi, are much(prenominal) likely to stomach the infection. During the next two to four days after the infection penetrates the body, the measles virus replicates in the respiratory cells and then spreads to the draining lymph nodes, where it reproduces again. Then it moves into the communication channel stream, carried by the white blood cells. This results in the virus being carried only over the body, which leads to infecting other places inside the body. During this time, the infected person feels fine and the measles infection and incubation stages are very unnoticeable. The next stage of the measles happens after eight to twelve days. The infected person has symptoms of fever, weakness and deprivation of appetite. Coughing and running of the eyes and nose are withal seen. at a time the infection is spreading all over the tissues through out the body. They also trigger the bodys repellent system, which causes the symptoms. When the measles virus infects the immune system and interacts with the antibodies and T cells, a measles rash begins on the typeface and very quickly spreads to the body, arms and legs. The fever and cough become more intense after the fifth day. The rash turns into 3-4 mm red maculopapular lesions, which are flat and slightly raised. Pretty much this virus starts on the face, hindquarters the ears, and moves downward all over the body. After awhile th e rash begins to disappear, barely the immune system is still weak. Making people who were infected with the measles more prone to other infections, making the immune system more susceptible to become infected, which in the early days of the measles caused umpteen deaths. With the growth of medical technology and research, a measles vaccine was produced. It is devoted to children before the age of four, and the measles infection is on the decline.
