New from ASTHO: Top Questions on Zika: Simple Answers


Zika virus is a mosquito-borne flavivirus transmitted to humans primarily by the Aedes aegypti mosquitoes, the same mosquitoes that transmit dengue, yellow fever, and chikungunya viruses. CDC estimates that 80 percent of Zika cases are asymptomatic. Symptomatic cases usually result in mild illness and symptoms such as acute onset of fever, rash, joint pain, and conjunctivitis. Some evidence suggests severe outcomes such as Guillian-Barre syndrome and microcephaly in infants via maternal-fetal transmission of Zika virus. There is currently no vaccine to prevent or medicine to treat Zika virus. For more information on Zika virus in the United States see CDC's Zika Virus web page: www.cdc.gov/Zika.


ASTHO staff have compiled the following links to selected resources and background materials that were created by state and territorial health departments and national and international sources for use by state health agency leaders. We'll add to these materials periodically.
