France on Wednesday confirmed its first Ebola case linked to the outbreak in the Democratic Republic of Congo, the first to be diagnosed outside the African continent.

The case comes as health authorities monitor a worsening outbreak that has infected more than 1,000 people in the central African country.

What do we know about the case?

The patient is a humanitarian aid doctor who recently returned from Congo, according to the French Health Ministry.

The patient "boarded a commercial flight from Kinshasa while virtually asymptomatic, experiencing only headaches," and his condition "deteriorated slightly during the flight" before he received immediate care upon landing in Paris, the ministry stated in a press release.
