A Call to Introduce Structured Zika Surveillance in India.

India has the climatic conditions conducive to year-round transmission of Zika virus, and a structured disease surveillance program should be implemented to prevent an outbreak. Such a program should (i) start screening before an outbreak arises; (ii) collect baseline data to assess future disease risk and monitor potential birth defects; and (iii) provide new insights into the ecology of the disease and inform public health policy following the one health concept.
