DAKAR, June 25 (Reuters) - The Democratic Republic of Congo has imposed a 21-day quarantine for anyone returning from ‌Ebola-affected areas before they can travel abroad, tightening ‌controls after France confirmed its first imported case linked to the outbreak.

• A ​June 24 decree signed by health minister Samuel-Roger Kamba requires anyone identified as a contact of a confirmed or suspected Ebola case to undergo 21 days of active health monitoring from ‌their last exposure. ⁠During that period, all travel, domestic or international, is banned unless expressly authorized by health authorities.

• ⁠The same monitoring rules apply to health workers, laboratory staff and response teams returning from affected areas, who must also obtain ​prior approval ​before travelling internationally.

• More broadly, ​anyone who has stayed ‌in an Ebola-affected province may only travel abroad after spending at least 21 days outside the area.

• All outbound international passengers are now required to complete a health declaration form issued by border health authorities, with airlines responsible for verifying ‌compliance as an additional screening measure.

• ​On Wednesday, France confirmed an Ebola ​case in a humanitarian ​doctor who boarded a commercial flight from Kinshasa ‌without symptoms but fell ill ​mid-flight, raising concerns ​about cross-border transmission.

• The outbreak, driven by the rare Bundibugyo strain, for which there is no vaccine or ​treatment, has infected ‌1,118 people and killed 291, according to government data ​released on Wednesday.
