Zika Virus News: Birth Defect Link Confirmed

The Centers for Disease Control and Prevention (CDC) has confirmed that Zika virus causes a severe birth defect called, microcephaly. The CDC report, published in the New England Journal of Medicine, shows there is no single piece of evidence, rather a number of evidence-based conclusions.

Mayo Clinic infectious diseases specialist Dr. Pritish Tosh says, "We know there is an association of the Zika virus infection with a certain birth defect, microcephaly, and we are finding out more about exactly what that risk is. It hasn't been defined. If a pregnant woman goes to an endemic area, what are the chances of getting infected, and then, what are the chances of developing microcephaly in their child?"

Dr. Tosh adds, "We are starting to also see new, more rare complications of Zika infection such as Guillain-Barre syndrome and other possible nuerological  manifestations."

The CDC also says sexual transmission is much more likely than anticipated. Dr. Tosh says, "The biggest concern remains protecting the woman and her unborn child. It's also important to note that the virus can exist in semen for months after infection. The recommendation is, if a man is infected, that he and his partner wait six months  before trying to have a child. If the woman is infected or for the woman who has traveled to endemic areas, the recommendation is eight weeks after travel or infection."

The CDC recommends women in the U.S. defer travel to endemic parts of the world if they are pregnant.
