Zika Virus: A New Threat and a New Kind of Pandemic

“Zika virus forces us to confront a potential new disease-emergence phenomenon: pandemic expansion of multiple, heretofore relatively unimportant arboviruses previously restricted to remote ecologic niches,” they write. “To respond, we urgently need research on these viruses and the ecologic, entomologic, and host determinants of viral maintenance and emergence. Also needed are better public health strategies to control arboviral spread.”

Question: Why is there now a pandemic of an “emerging” Zika mosquito borne virus, now that we have increased research into just that? Mosquitoes as vectors for disease. According to wikipedia, Zika has been very rare until 2007 and the recent cases.
