I saw on the news that one Jewish Orthodox community in Brooklyn, New York, is rife with anti-vaxxers. One family travelled to Israel with an unvaccinated child, who caught the measles there.
Because measles are so extremely contagious, the virus spread throughout the community. One man was visiting the Orthodox community, and didn't realize he had caught the measles.
He began to travel, (became known as patient zero), and infected 39 additional people. One of the places he stopped was my favorite Burger Joint downtown, in Plymouth, Massachusetts. He exposed the bartender/waitress, and every person she served for two days until she was notified.
By the time he got done exposing/infecting people, and the exposed got done exposing people, hundreds of people had been exposed. Hundreds....from ONE man.
What really burned my butt about the whole thing was the whinging, entitled, and idiotic response of one of the mothers from the origin point of that exposure. She and all the other mother's in that Jewish Orthodox community were told that they could not bring their children back to public school until they had been vaccinated for measles.
Her response to the school was that THEY were violating HER rights. Ignoring the fact that a percentage of children (I think it is 3%) who contract measles actually DIE.
If I had my way, I would send her kids to school with a couple dozen kids with severe cases of head lice, and shut them all up in a room together. I'll bet you anything she would be the first one to start screaming that her children were being infected with head lice due to the severe negligence of the school department and their total disregard for public health.
