Elsevier still charge for papers on Zika

II thouhj

I thought that all major publishers had agreed to make papers on Zika available for free as a public service.
But I was wrong. Elsevier are charging people. Admittedly I haven't read this paper as I'd have to pay. But I think it's about Zika.
Prediction: we'll have a mail from Elsevier saying "this is part of our bumpy road. We'll still not fully competent to manage Open Access, so please forgive us and it will take some more years to get it right. Meanwhile we'll continue to charge you."
NOTE. This paper wasn't difficult to discover – I found it on Europe PubmedCentral http://europepmc.org/. I just typed "Zika"
