David doesn’t interview Jim West, as much as have a discussion with him. Jim is claiming that the cause of microcephaly in Brazil was not Zika, or pesticides, or vaccines, but an increase in the rate of prenatal ultrasounds, mostly from a new telemedicine network called, “The Network”, that remotely provided interpretation of ultrasounds. But what is the definition of microcephaly and are all smaller than normal heads indicative of future problems in the baby? Can we be sure that the so called epidemic just wasn’t an epidemic of measurements? Also, head measurements might be used as a surrogate for overall growth, but will be used to diagnose microcephaly instead of overall growth problems. Perhaps the fundamental question is when medicine introduces a new technique, whether a new vaccine or a new machine, how do we know if it’s causing problems?
