"In an abundance of caution, we have activated the appropriate infection control protocols, including isolating the patient," she said. "Our medical team continues to evaluate and monitor progress in close collaboration with the CDC and the Department of Health."
Just hours later, Shady Grove Adventist Hospital in Rockville, Md., north of Washington, confirmed that it was evaluating a patient who "presented with flu-like symptoms and a travel history that matches criteria for possible Ebola."
But on Friday night, Shady Grove Adventist officials said they had ruled out Ebola. "Our medical team has determined that the patient has malaria and does not have Ebola," the hospital said in a statement.
While Ebola continues to devastate West African nations including Liberia and Sierra Leone, the outbreak in Nigeria – where the Howard patient had traveled – may actually be coming to an end, with no new cases since Aug. 31, the CDC reported earlier this week. At one point, 894 people in Nigeria were being monitored since they had come into contact with someone sick with Ebola.
