Is zika virus deadly?

The Zika virus usually produces symptoms so mild that many people don't even realize they are infected. It seldom puts anyone in the hospital, much less kills them; a few people die from Zika, but deaths are very rare.

The deadly part of the virus comes from the effects on babies born to women infected with the virus during while pregnant with the baby. The virus causes microcephaly in the baby, which can cause life threatening problems such as seizures and difficulty swallowing, although mostly microcephaly results in serious mental disability, problems with motion and balance, blindness and deafness.
