Najera \/ The history of vaccines blog<\/a><\/p>\n According to the best evidence we have,\u00a0measles makes its appearance somewhere between the 11th and 12th Centuries<\/a>\u00a0when the measles virus diverged (separated) from the rinderpest virus (a sort of measles of cattle\u00a0that has been eradicated through vaccination<\/a>). This probably happened when cattle herders spent just a little too much time with their cattle somewhere in the Middle East.<\/p>\n Before we go any further, you need to understand that measles is highly infectious. It\u2019s, like, really infectious. One person can infect up to 18 other people, and the virus floats in the air for up to two (maybe four) hours where an infectious person has been. What\u2019s worse, a person is infectious 3 to 5 days before the onset of the typical measles rash, and 1 to 2 days before the onset of fever. This means that a perfectly healthy-looking person can go around spreading measles and not even know they\u2019re sick.
