Dr. Nancy Khardouri has been studying and treating infectious diseases for the past 30 years. She says the test is one of the main concerns with the Ebola virus.
Even if a person is infected with Ebola, test results will be negative until enough of the virus builds up in the person’s body.
“The test becomes positive when you have symptoms. So it doesn’t help you before the symptoms, like many other tests do,” Khardouri, director of infectious disease at Eastern Virginia Medical School, explained.
