BERLIN — Dr. Peter Stafford, a physician, arrived in the U.S. on Monday with his wife Rebekah and their four children after recovering from Ebola. Stafford contracted the Bundibugyo ebolavirus while working on a humanitarian mission in Congo.

Stafford was evacuated to a hospital in Berlin on May 20. He has been Ebola-free since May 30 and was discharged from the Berlin hospital on June 6. Rebekah Stafford, who is also a physician volunteering with Serge, a Pennsylvania-based Christian missions organization, was evacuated with their four children and placed in quarantine.

During their quarantine, Rebekah Stafford and their children did not develop symptoms of Ebola. There are currently no approved vaccines or treatments for the Bundibugyo strain of the virus. The strain occurs less frequently than the Zaire strain of the virus.

The outbreak in Congo has spread to Uganda. As of Saturday, Congo's health ministry reported 782 confirmed cases and 178 confirmed deaths in the country. As of Sunday, Uganda's health ministry reported 19 confirmed cases and two confirmed deaths.

Dr. Peter Stafford expressed gratitude for his recovery. "I am filled with gratitude to God for preserving my life, to all those who prayed on my behalf, and to the many medical providers who cared for me," Stafford said.

He also commented on his current condition and ongoing prayers. "I am feeling well and thankful to be reunited with Rebekah and the kids. Our prayers continue for those in Congo who are facing this epidemic and for the ongoing efforts to control the disease," Stafford said.

No independent assessment of Dr. Peter Stafford’s claims was available.
