Brazil Links Dengue-Like Virus to Birth Defects in Babies

 Brazilian health officials believe pregnant women are more vulnerable of developing fetuses with microcephaly if they are infected with Zika in their first trimester. So far in 2015, the ministry has reported 739 cases of babies born with microcephaly in nine states that have been hit hard by Zika infections, while last year the same region reported only 45.

In its statement, the Health Ministry reported two other deaths associated with the Zika virus not involving microcephaly. The victims were an adult male who suffered from lupus and a 16-year-old girl.
"Research on the subject should continue to clarify issues such as how it is transmitted, what it does to the body, how the fetus gets infected and the time of greatest vulnerability for pregnant women," the ministry's statement said.
Researchers with the U.S. Centers for Disease Control and Prevention are coming soon at the request of Brazil's government to study the link between the rare neurological condition and Zika.
Microcephaly "usually reflects an underlying reduction in the size of the brain," according to the CDC. The disorder can affect motor skills and cause mental retardation.
The same mosquito that carries the dengue virus, Aedes aegypti, is also responsible for spreading Zika, a disease that until now was known as a mild version of dengue with symptoms such as fever, rash and joint pain.
Before Brazil, outbreaks of Zika have occurred in Africa, Southeast Asia and the Pacific Islands. The virus is not found in the United States, but cases of Zika have been reported in returning travelers, according to the CDC.
