JOHANNESBURG (AP) — South Africa’s coronavirus cases jumped to 402 Monday, up 128 from the day before, continuing worrying exponential growth and making it the country with the most cases in Africa.

South African President Cyril Ramaphosa is expected to speak to the nation about the growing threat and many expect him to announce new restrictive measures to try to slow the spread of the disease.

More than half of South Africa’s total cases are in Gauteng province, which includes Johannesburg, the country’s largest city with 5.7 million people, and the capital, Pretoria, with 2.4 million, according to figures released by the government health ministry.

South Africa has overtaken Egypt to become the African country with the highest number of cases. South Africa has not registered a death from the disease. The majority of cases are travelers from Europe and other countries, but the number of cases that are locally transmitted is rising.
