WCG just announced the Zika project available now including Android.

Dear ipkh,
In 2015, the Zika virus began to spread rapidly throughout the Americas. Not only can Zika cause neurological complications in adults who become infected, the disease also has been linked to severe brain development issues in some babies whose mothers were infected during pregnancy. Through our new OpenZika project, we're working with an international team of researchers to find an antiviral drug to combat this disease, and we need your help!

Thanks for your support,

I've had it selected since yesterday but don't know if any have come my way.

I had just zika selected and wound up running out of units. So I added the send other work option and seem to get them again.
