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...
