New from ASTHO: Top Questions on Zika: Simple Answers

Background

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.

Resources

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.

American Society of Tropical Medicine & Hygiene: First International Conference on Zika Virus
This international conference is scheduled for Feb. 22-25, 2017 in Washington, D.C. The conference is designed to provide an up to date panorama of the virus from a medical and geographical point of view. More information including how to register and program information can be found on the conference website.

Texas Department of State Health Services Confirms First Non-Travel Related Case of Zika Virus in a Pregnant Woman
On Jan. 25, Texas announced the first instance of a laboratory-confirmed Zika infection in a pregnant Texas resident who did not travel outside the state. The woman, a resident of Bexar County, traveled to Brownsville in November, around the time six Brownsville residents acquired cases of Zika virus disease from mosquitoes there. She did not get sick and was tested for Zika during regular prenatal care. Because the infection was not transmitted in Bexar County, it does not represent an increased risk of Zika there. Texas DSHS encourages their citizens to continue to protect themselves from mosquito bites in parts of the state where mosquito activity is present throughout the winter months. Additional Zika virus updates from Texas DSHS can be found here.

New Virtual Training on Vector Control for Environmental Health Professionals Now Available
CDC Environmental Health Services and Tulane University School of Public Health and Tropical Medicine announce a new virtual training on using integrated pest management to control vectors that spread pathogens, including Zika virus. Vector Control for Environmental Health Professionals (VCEHP) training will provide participants with the latest science and evidence from vector control experts and allow them to access concrete principles, practices, and resources for vector control. Continuing education units are available through the National Environmental Health Association. Registration is free and the training is available to complete at any time. More information about the course topics is available on the website.
