This leads me to believe there's strong enough evidence that Zika is a problem for pregnancy.
There's no doubt cause for concern with pregnancy. But even that article notes that the evidence is far from conclusive:
“We still don’t understand the factors that contributed to the striking number of congenital birth defects seen during this pandemic,” Eva Harris, a professor at U.C. Berkeley’s School of Public Health who studies dengue, Zika, and other emerging infections, told me. “Possible explanations include the vast number of people infected—a numbers game. There could be other factors, such as the viral strain, the genetics of the host, environmental exposures, or immune-related factors, such as prior dengue infection.”
And with respect to non-pregnant patients, the article reports that many cases are non-symptomatic, and those that are typically resolve within a week or less. Except for the potential for birth defects, cases of which are still largely confined to Brazil, Zika is far less dangerous than Dengue, Malaria, Yellow Fever, and Chikungunya, all of which are also transmitted by mosquitos.
