How the anti-vaccine movement targets cities – and creates disease ‘hotspots’
Densely populated areas are vulnerable to dangerous outbreaks of infection such as measles – and to the spread of misinformation
Just a 30-minute drive from Portland, Oregon, is Washington’s Clark County, home to one of the largest outbreaks of measles in the US. Of the 70 or so confirmed cases, the majority are unvaccinated children under the age of 10.
In a country that had previously eliminated measles, in 2000, hundreds of children are being kept out of school to avoid exposure to the disease. It is so contagious that if one child is diagnosed, all are considered at risk.
