The US Coast Guard says it has retrieved a blood sample from a Dallas health care worker who is aboard a cruise ship and being monitored for signs of Ebola.
Petty Officer Andy Kendrick says, the crew flew in a helicopter on Saturday to meet the ship and lowered a basket of supplies. The woman provided a sample.
Mr. Kendrick had no further details about how the sample was taken. He says the decision to take the sample was made in coordination with the federal, state and local health authorities.
Officials have said the woman poses no risk because she has shown no symptoms and has voluntarily self-quarantined.
Mr. Kendrick says the sample was taken to a state lab in Austin for processing.
The ship is scheduled to return to Texas on Sunday morning.
