Since Zika virus disease usually manifests in an asymptomatic manner, the detection becomes difficult. Moreover, Zika virus infection in pregnant women can cause fatal brain conditions in infants and other nerve damaging diseases in adults. This calls for Zika virus screening in endemic regions. However, the expense, time taken to obtain results and lower accessibility to testing laboratories limit early detection of the virus. A study conducted at the Washington University has reported a novel paper-based detection method that uses nano-particles.
