UC Davis Researcher: What Repellents and Doses Are Best to Prevent Zika Virus

Working on zika-virus research are UC Davis chemical ecologist Walter Leal (foreground) and colleagues and co-authors Rosangela Barbosa (center) and graduate student Gabriel Faierstein of FIOCRUZ-PE, Recife, Brazil.

If you're traveling to—or living in--a Zika virus-infested area, it's far better to use DEET rather than Picaridin and to use higher, rather than lower, doses of DEET because lower doses do not work well with older mosquitoes, newly published...

Breaking News: Zika Virus Found in Wild-Caught Culex

Culex quinquefasciatus, the southern house mosquito,is known for transmitting the West Nile virus, but now the Zika virus has been detected in wild-caught C. quinquefasciatus in Recife, Brazil, the epicenter of the Zika epidemic. (Photo by Kathy Keatley Garvey)

The news is out.  It's what they've been searching for. In a groundbreaking discovery, a scientific team of Brazilians and Brazilian-born chemical ecologist Walter Leal of the University of California, Davis, has announced that the Zika virus has...
