The measles virus is a highly contagious virus that is especially common in young people but can be contracted by any person. It is not common in animals. The known origin of the measles virus stems from the divergence from the rinderpest virus between the 11th and 12th centuries, when humans and livestock lived close together. The measles virus, or MeV, and the rinderpest virus, or RPV, are closely related. The divergence between the two viruses that occurred in those two centuries was unexpected because when MeV emerged it was said to have occurred in prehistoric times. Say no to plagiarism.

However, the first two people to isolate the measles virus were John F. Enders and Thomas C. Peebles in Boston, Massachusetts, in 1954. The measles virus is a virus classified as mononegavirales. Mononegavirales is the taxonomic home of many other measles virus-related viruses, such as Ebola virus, mumps virus, and rabies virus. The host of the measles virus is the human body, but also lymphoid tissues and the circulation. The virus also lives in the mucus of the throat and nose of the infected person. The measles virus spreads via aerosols and droplets that can come from a person coughing on something or someone or from a person touching an object and then another person touching the same object and then touching their mouth. It can also spread through a sneeze: After a person sneezes, the measles virus can remain in that airspace for up to two hours. It also spreads by entering host cells and taking over host DNA replication. What usually happens first is that the virus comes into contact with a host's lung tissue, then infects the lung's immune cells, also called macrophages and dendritic cells. These cells act as an early warning and defense system for other cells. Next, the infected cells move to the lymph nodes and from there transfer the virus to T and B cells. The measles virus does not reproduce like any other common bacteria. In the measles replication process, a newly synthesized genomic RNA is tightly wrapped by an N protein and thus provides a helical template for a viral transcript. Measles has effects and can show symptoms on its host and some are not very good. Some of the symptoms that measles has on the host are fatigue, fever, pain all over the body, red eyes, especially muscles, loss of appetite, malaise, sneezing, runny nose, pink eyes, dry cough, rashes, ache sore throat, sensitivity to light, headache, diarrhea, ear infection, swollen lymph nodes and Koplik's spots. Some of the effects it can have on a host are those listed above or even worse, such as pneumonia, permanent brain damage, deafness and, worst of all, death. Despite all these negative effects, there are ways to help it, however there is no cure. Some of the ways symptoms can be treated are post-exposure vaccinations, which for non-immunized people, including newborns, receive a measles vaccination within 72 hours of exposure to the measles virus.
