In clаss we discussed the increаse in cаses оf micrоcephaly in babies bоrn in Brazil in 2015. Some individuals thought this increase was due to a mosquito borne disease called Zika. Others were concerned that a mosquito larvicide (Pyriproxyfen) was responsible for the increased microcephaly. In this case the statement that Pyriproxyfen causes microcephaly is a [ans1]. To try to get at the answer for what is causing the increased cases of microcephaly, scientists have looked regionally at the frequency of microcephaly cases and frequency of the larvicide use, with the idea that if there were a positive relationship between the two, that would give [ans2] . Scientists have also done controlled laboratory studies in which they have exposed laboratory animals to the Zika virus and found those exposed to the virus during pregnancy had offspring with a higher incidence of microcephaly, suggesting a [ans3] between the zika virus and the microcephaly condition in the laboratory animals.
