On Friday, Puerto Rico reported its first case of a baby born with Zika related microcephaly infection, raising concerns because officials said the medical condition wasn't diagnosed until the mother was nearly eight months pregnant.

According to Health Secretary, the baby was born with severe brain defects and hearing problem and remains hospitalized.

In Puerto Rico, the first case of Zika infection was reported last December. The centers of Disease control and prevention had warned that as many as 50 women a day could be getting infected by Zika virus.

There are 31,500 cases reported of Zika in Puerto Rico, including more than 2,400 pregnant women. There are 233 people have been hospitalized and have been reported so far. The new research reported that the number of pregnant women is more than four times larger than recorded.

The authorities are investigating the case of the late report of microcephaly infection although the mother affected Zika symptoms during the month of her pregnancy but the infected mother did not continuous parental care during her pregnancy, reported by Medical Press.

Health secretary Ana Rius disagreed to provide any other details except to say that the case occurred in the capital of San Juan. All the pregnant women there with Zika symptoms should be seen by a doctor at least three times during pregnancy with fetal ultrasounds each time.

 According to The New York Times, Five other pregnant women in Puerto Rico have microcephaly symptom will give birth between November and January, that has warned by The Centers for Disease Control and Prevention.

The child would say to be monitored until she the age of 3 under the Zika Active Surveillance System, as are all children born from Zika infected mother, said by CDC official Anna Rius.

The CMV or Rubella virus affected babies have appeared normal at birth, but later turn serious problems with hearing, vision, and learning. The CDC officials want to know "Is Zika carries the same risk"?
