Rubella is caused by a virus called rubella virus. It is also called German measles. In this the person develops rashes all over the body and this disease may easily spread to other person by contact or by air hence it is contagious. It is usually common in children. There are few symptoms of the rubella that include mild fever and headache; the adult may even not notice the symptoms because its symptoms are very similar to the flu.
The rubella virus can be prevented by vaccination by MMR vaccine which is a combined vaccine for measles, mumps and rubella. It generally makes the individual permanently immune to the virus. Diagnosis can be done by the blood test. But once the person has this disease it cannot be treated. Only medications are given to reduce the symptoms.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
