Have you ever had, or suspected you had, an infection with dengue, chikungunya, Zika or West Nile virus?
Have you been vaccinated against yellow fever virus or Japanese encephalitis virus?
We are looking for volunteers who suspect they have been infected with, or have been vaccinated to prevent, a mosquito-borne infection for a study being conducted by OHSU.
Every year mosquito-borne viral infections affect over 100 million people living in tropical regions of the world. Dengue fever, caused by the dengue virus, is the most common mosquito-borne viral infection, while the Zika virus and chikungunya virus, also transmitted by mosquitoes, have recently emerged worldwide. There are no vaccines or specific treatments for these viral infections, but OHSU scientists are working to understand human immunity to these viruses following infection in order to make effective vaccines.
If you’ve had dengue fever or another mosquito-borne virus, such as chikungunya or Zika, or been vaccinated for yellow fever or Japanese encephalitis, your participation in this study will help determine what parts of the immune system make an effective vaccine and prevent infections in men and women who are at risk for infection. This study is research and not treatment.
