(CNN )A researcher at the University of Pittsburgh accidentally infected herself with the Zika virus while working in a lab, the university said.
The woman stuck herself with a needle May 23 while conducting an experiment with the virus. Nine days later, she began experiencing symptoms consistent with the virus, including a fever. They subsided, and she returned to work Monday. Two days later, the university received confirmation a test was positive for the mosquito-borne illness.
