New York Times (Sept. 19, 2016): Want a Zika Test? It's Not Easy, by Roni Caryn Rabin:
Getting a Zika test is harder than you thought, even for people who have recently traveled to areas where Zika is a big problem and who are planning to have children. People are discovering that you cannot simply show up at a public health department and be tested on demand.
The difficulty stems from a Centers for Disease Control directive establishing strict guidelines for Zika testing. The guidelines give priority to pregnant women with possible exposure to Zika and to people with Zika-like symptoms. This leaves out people who have possibly been exposed to Zika and are trying to conceive. The guidance for this population is that they engage in protected sexual intercourse for at least eight weeks after their fear exposure. The World Health Organization recommends six months of protected sexual intercourse before trying to conceive. These recommendations are meant to prevent an onslaught of requests for Zika testing that would swamp local public health authorities. They also help define when insurers will cover Zika testing.
Testing for Zika is a complex process that may require three tests for a conclusive result. There is no test for detecting the infection in semen, however.
