7. A man comes in for evaluation at the request of his wife, who is three months pregnant. He returned three days ago from a two-week business trip to Brazil. Four days before departure he developed a mild, transient illness consistent with a viral infection that lasted three days; he now feels well. His wife is concerned he may have had ZIKV. At this juncture, the best management course is to

• perform serum ZIKV RT-PCR testing; if negative, no further testing is necessary.
• recommend condom use for two weeks as a precaution and perform serum anti-ZIKV IgM antibody (ELISA) testing; if negative, no further testing is necessary.
• reassure him there is no need for laboratory diagnostic testing or any other precautions, as his risk was low, his symptoms are nonspecific, and he is now asymptomatic.
• perform serum and urine ZIKV RT-PCR testing and request anti-ZIKV IgM antibody (ELISA) testing if the results are negative, and advise strict condom use as a precaution to prevent sexual transmission until the diagnosis is clarified.
