The Canadian government said Tuesday that travelers from Ebola-affected regions will be required to self-isolate for 21 days, and that immigration authorities are temporarily suspending decisions on applications from Congo, South Sudan and Uganda.

Luc Brisebois, director-general for the Centre for Border and Travel Health at the Public Health Agency of Canada, said the measures are being implemented out of an “abundance of caution” and will stay in place until Aug. 29.

Travelers who have symptoms will be transferred to hospital for further medical assessment. The stricter border measures are being implemented starting Saturday, and those who do not have somewhere to isolate will be provided with a place.
