Zika virus was isolated in 1947 in the Zika forest of Uganda. Although the disease's symptoms are generally mild and include low fever, headaches and joint pain, Zika's rapid spread has raised alarm in Latin America due to its association with several more serious health conditions.
That caused researchers to scramble and find a link between the virus and microcephaly in babies-a neurological condition that causes abnormally small heads and developmental delays. They were already running a study of dengue virus, asking pregnant women to come in and be tested if they showed symptoms of dengue, such as a rash. The bleakness of the results was startling.
The findings, together with other studies, support what most experts already believe: that Zika is causing an epidemic of birth defects. Tang, along with researchers at Johns Hopkins University and Emory University, found that the virus, which was discovered in 1947, directly targets a cell type called human embryonic cortical neural progenitors in as little as three days after being exposed to the virus.
But it raised alarm when Brazilian health officials reported an apparent surge in babies born with microcephaly, which can signal their brains didn't develop properly. "Anyone who is planning travel to a country with active Zika virus transmission should consult their doctors before leaving, especially if they are pregnant or are considering becoming pregnant".
Trump's detractors hope that a series of disappointing losses Saturday for Trump could signal a break in the populist momentum that has swept him to the top of the polls.
