Uganda has told 22 foreigners who refused to self-quarantine on arrival for a business forum to return to their home countries.

Uganda's Health Minister Jane Ruth Aceng said the 22 travellers had arrived from "category one" countries deemed high-risk in the ongoing coronavirus outbreak.

The ministry has categorised Italy, Iran, South Korea, France, China, Germany and Spain as countries whose citizens have to undergo self-quarantine for 14 days even if they do not have coronavirus symptoms.

The 22 travellers were informed of the self-quarantine requirement on their arrival at Entebbe International Airport.

They refused to observe the rule and instead opted to return home.

Uganda is hosting a two-day business forum that is being attended by delegates from Europe.
