The Zika virus has quickly become a major health threat, and researchers at Virginia Tech are looking for ways to curtail its spread.
The virus, which is primarily spread to humans by the bite of an infected mosquito, has been passed on to a growing number of Americans since early 2016, and the World Health Organization has declared it a Public Health Emergency of International Concern.
Biochemist Zhijian “Jake” Tu is one of several Virginia Tech researchers zeroing in on the Zika virus. Tu is studying genes that turn biting female mosquitoes into males, and he is exploring genetic strategies to stop the transmission of the Zika virus by reducing the number of female mosquitoes. Male mosquitoes do not bite and are harmless to humans, while female mosquitoes bite humans to get the blood they need for egg production.
