HHS Department And The Pan American Health Organization Hold Briefing On Zika Outbreak

WASHINGTON, DC - MAY 3: Dr. Sylvain Aldighieri, Zika Incident Manager for the Pan American Health Organization (PAHO), listens to a question during a media briefing concerning the Zika virus, at the Pan American Health Organization headquarters, May 3, 2016, in Washington, DC. Researchers have recently discovered the Zika virus in a second mosquito species. Known as the "Asian Tiger" mosquito, (formally named Aedes albopictus) the species stretches much further north into the United States than the previously known Zika carrying Aedes aegypti species. The discovery was recently reported in the April 21 "Zika - Epidemiological Update" report issued by Pan American Health Organization and the World Health Organization.
