UPDATE (2): Sick Woman at Pentagon Does Not Have Ebola

Update at 5:10 p.m. — Arlington County officials say in a press release that the woman who was sick at the Pentagon this morning does not have Ebola.

Based on the public health investigation, which included the travel history of a woman who became ill this morning in a Pentagon parking lot, and on questioning of her by medical staff, medical authorities are confident that she does not have Ebola.

Arlington County Fire Department Emergency Medical Services transported the woman to Fairfax Inova Hospital Friday morning, after she became ill in a Pentagon parking lot. The woman had displayed symptoms consistent with the virus and her travel history was uncertain. She was put in isolation at Fairfax Inova Hospital. Arlington County took all necessary precautions to protect public health during this event, including activating its Emergency Operations Center. We are beginning to break down those operations now.

(Updated at 5:05 p.m.) Arlington County’s responded to the Pentagon this morning due to an possible Ebola case on a tour bus.

Medics responded to the Pentagon this morning for a report of a woman on a bus who was sick and vomiting. When they were told that she had recently arrived from Africa, the hazmat team was called out of “a complete abundance of caution,” Pentagon Force Protection Agency spokesman Chris Layman told ARLnow.com.

A large portion of the Pentagon south parking lot was cordoned off with caution tape, and police are telling those who don’t work at the Pentagon to avoid the immediate surrounding area.

The woman — who reportedly boarded the bus at the Pentagon, got sick in the bathroom then got off — was transported via ambulance to a Inova Fairfax Hospital. The county’s medical director also responded to the call and went to the hospital with the patient, according to scanner traffic.

A tipster with knowledge of the emergency response told ARLnow.com that the patient claimed she recently traveled from the West African nation of Sierra Leone. That was confirmed by D.C. health department officials. However, an Associated Press report is now questioning whether she has, in fact, been out of the country.

The tipster also said that four Arlington firefighters were held at the hospital for much of the day due to possible exposure, and are now monitoring themselves for signs illness. That tip could not be immediately confirmed. The AP is reporting that seven Pentagon police officers might have also been exposed and are being monitored.

Despite numerous Ebola scares in the United States, there have been fewer than 10 confirmed cases in the country. Today President Obama named an “Ebola czar” to help coordinate the federal response to the outbreak threat.
