This link shows the patent on the Zika virus. There's also a link on the lower left on the page that tells you "how to order".
Zika virus ATCC ® VR-84™
And here, under their FAQ section, is this:
Does ATCC distribute the Zika virus?
Yes, Zika virus (ATCC® VR-84™) strain MR766 has been distributed by ATCC since 1953. The virus is available through ATCC, and our designated International Distributors, for Research Purposes Only.
Due to the recent high demand, the strain is currently on backorder pending production of a new lot.
Zika only lately started becoming a problem, so I'm wondering why this was patented decades ago? Why did it need to be brought to America in the first place?
