That reference is to a letter from an anti vaccination organisation. The link provided in that letter is shown below and is a dud. If you can provide a credible research paper that the death rate is 1 in 10,000, I will look at it.
recent outbreaks suggest that 1 in 1,000 is about right. Measles is a notifiable disease so the idea that only 1 in women cases is actually reported does not stack up.
