my mom is a fan of dr oz and i looked at the website today to see about the 'vegan before 6' plan.
i saw he did a past show on parasites and specifically discusses babesia. he quotes an estimate by the CDC that 60 million 'of you' - i assume 'Americans', have parasitic infections and dr oz says he thinks that's likely conservative.
i was pretty surprised to see this in the mainstream. if interested, you can google it and search his past episodes.
