The recent report with detail on the initial Zika cases in the Wynwood area of Miami, Florida cites 14 symptomatic cases among the 30 employees, suggesting an attack rate approaching 100%.

Only about 20% of Zika infections cause symptoms, so symptoms in almost 50% of the workforce suggests virtual all were infected over the six-eight week period, which began in early June.

The early date also suggests that many local residents who were infected in June would test negative on urine tests on samples collected in late July or August.

 

Fourteen of the roughly 30 employees who work at the business in Wynwood reported they had typical Zika symptoms such as fever, rash, joint pain or conjunctivitis from early June to mid-July, according to the report.
