The CDC has told state health officials to brace for an end to federal funding for efforts to track Zika infections and birth-defects that are caused by the disease.
The damage caused by Zika in babies with microcephaly is unique enough that doctors believe they may soon be able to identify it as the likely culprit in a case by looking at brain scans alone.
Until now, scientists have assumed the Aedes aegypti mosquitos carry the Zika virus. New research indicates an even more common mosquito may transmit it.
Officials from the CDC have arrived in Brazil to investigate whether the Zika virus may be behind the mysterious uptick in babies born with the birth defect known as microcephaly.
Zika is the latest in a triple-whammy of mosquito-borne illnesses that has pushe Brazil's universal health care system past its already stretched capacity.
Doctors, health workers and patients are finding novel ways to share the latest on the Zika pandemic. But is the exchange of information on closed networks inhibiting a public health response?
Despite mounting evidence suggesting a link between Zika and the devastating birth defect known as microcephaly, many in Brazil believe a bad vaccine is to blame.
