Antibody testing is usually performed on the blood or on fluid taken from the spinal column (cerebrospinal fluid).
Limitations of antibody testing: Zika antibodies might be detected in some people’s bodies for longer than in others’.
A pair of private companies, Inovio Pharmaceuticals and Gene One Life Science, said last week they had begun tests of a different DNA vaccine against Zika, and were testing it on volunteers in Miami. has registered more than a thousand Zika cases already, but until last week all involved overseas travelers or their partners.
“DNA vaccines are relatively new entities but they look like they’ll be effective,” says Joel Maslow, chief medical officer of Gene One. Over the weekend, however, officials confirmed four cases in Miami had been acquired locally, meaning the virus has gained a foothold among mosquitoes in the city.
Affected children also exhibit delays in the acquisition of skills requiring the coordination of muscular and mental activities (psychomotor disability) and moderate to severe intellectual disability.
Additional symptoms affecting different organ systems of the body can also occur.
But for people with more than one possible exposure or ongoing exposure, a positive antibody test cannot tell them when the infection happened.
Another limitation to antibody testing is that even a very good test can result in a high number of false positives in areas where there is not widespread Zika transmission.
Most cases are thought arise from spontaneous (de novo) genetic errors very early in embryonic development.
The symptoms of cri du chat syndrome vary from case to case.
Together, you and your health care provider can decide whether or not you should be tested for Zika, based on your individual circumstances.
