The Zika virus has been known for quite some time, but it gained notoriety recently due to its possible linkage to birth defects.
Science News has a summary report on Zika virus:

A report on the studies of its possible linkage to microcephaly, a birth defect of babies with undersized and underdeveloped brains:

In short, studies are continuing, evidence is mounting, but still not quite a confirmation.

Are you the same person who made this same claim last time this came up? I went looking for evidence to substantiate your claim, and what I found was that everywhere Zitka is associated with neural abnormalities. This makes it causing microcephaly quite plausible. It's not an inevitable effect, so it probably depends on exactly what stage of the pregnacy the infection occurs in, and on how severe a case the infection is. Also most people who catch Zitka have minor symptoms, minor enough that it often isn't reported. This would make tieing the cause to the result difficult.
My guess is that this is an effect of Zitka that has always been present, it just hasn't been noticed. Detecting it depends on good public health records and lots of statistical correlation. And being able to test for residual antibodies. Etc. Things that have only recently started to become widely available.
