NAIROBI, Kenya — South Sudan has joined a growing list of African countries reimposing COVID-19 pandemic restrictions as infections rise again.

A statement by the national COVID-19 task force bans all social gatherings including religious and sporting events, and it closes schools.

Businesses attracting crowds including bars and nightclubs are closed, and public transport is limited to half capacity. All incoming air passengers must show proof of a negative coronavirus test.

And law enforcement officers have been told to take immediate action to impose the order. South Sudan has more than 3,900 confirmed virus cases but has limited testing capacity.
