In South Africa, spreading false information about the coronavirus is now a crime, punishable by up to six months in prison, a fine, or both.
The move is one of several new measures announced by the government late Wednesday, in an effort to halt the spread of the virus and curb misleading rumors on social media.
Other measures include legally enforcing testing, treatment and quarantine or isolation of suspected cases.
Earlier this week, a family in Gauteng province refused to be isolated after testing positive and had to be brought in by police after a court order.
Visits to prisons have been suspended, and gatherings of more than 100 people are now prohibited by law. Gatherings of more than 50 people will also be banned if alcohol is present.
South Africa has 116 cases of the coronavirus, according to Johns Hopkins University -- most of them imported from overseas.
