Zika disease can cause stillbirth>>>>>

Having established the relationship between Zika disease and birth defect, the recent case study described in PLOS Neglected Tropical Diseases adds to the level of concern.
According to researchers, a case of stillbirth that involve a Brazilian mother, infected with Zika diseas raises suspicions that the virus may be capable of doing more damage to fetal tissue than previously thought.
 The study reveals absence of the baby's brain, according to the research,The brain was covered with fluid instead of brain tissue. The baby also had abnormal pools of fluid in other parts of its body. 

The World Health Organization have declared Zika a global health emergency and estimated the disease could eventually affect as many as 4 million people in the Americas and may spread to parts of Africa and Asia, while stating that the only way of avoiding the disease is to avoid the vector. 

Stillbirth  is when a baby is born dead after 24 completed weeks of pregnancy. 

The study was led by Yale University tropical disease expert Dr. Albert Ko along with Dr. Antonio Raimundo de Almeida of Roberto Santos General Hospital in Salvador, Brazil. 

According to KO, it is hard generalize since the case study was carried out using details of just one individual patient, however,
  they are unusual. In addition to microcephaly, he noted that the fetus had no brain tissue left. "It was just fluid."
Fluid also filled the lungs, abdomen and other tissues.

These resulted from a condition known as hydrops fetalis in which the fetus loses the ability to manage body fluids. 
The fetus also had arthrogryposis, a condition in which joints don't move normally and may be stuck in place. He calls for further research to verify the relationship between Zika and hydrop fetalis. 

The fact that around 73% of Zika infections do not produce symptoms compounds the problem. It is almost impossible to trace through a population; as the authors say, only future studies can confirm this new finding.
