A total of 373000 cases have been confirmed in South Africa, sounding the alarm of the epidemic in Africa.

According to epidemic data released by Johns Hopkins University in the United States, as of 15:00 on July 21, a total of 373628 cases and 5173 deaths have been confirmed in South Africa. On the 20th, 9300 new cases were confirmed in South Africa in a single day, and the recent daily trend in South Africa has entered a fluctuation range of 10-13000, and the probability will continue to rise, so the epidemic situation is not optimistic.

At present, the situation of epidemic prevention and control in South Africa is grim. The World Health Organization said on the 20th that it was shocked by the spread of the new crown virus in Africa and warned that the rise in cases in South Africa could be a "harbinger" of an outbreak across the continent. At present, the epidemic in South Africa is spreading at a high speed. Since the end of June, the cumulative number of confirmed cases in South Africa has rapidly exceeded that of many countries, including Peru, Chile and other South American countries that also broke out later. At present, the cumulative number of confirmed cases in South Africa ranks fifth in the world. Although there is still a large gap between the cumulative number of confirmed cases in South Africa and the fourth Russia, the number of new confirmed cases in South Africa in a single day is nearly twice that of Russia. If the spread of the epidemic is not controlled in time, it may follow the same path as the United States, India, and Pakistan.

At the same time, the spread of the epidemic in South Africa has also sounded the alarm for the entire African continent. Michael Ryan, director of the WHO Health Emergency Project, said at a regular press conference on WHO's new crown pneumonia on July 20 local time that the epidemic in Africa is continuing to accelerate, and the number of cases in many African countries has increased rapidly in the past week. For example, the number of cases in Madagascar has increased by 50%, Zambia by 57% and Zimbabwe by 51%.

Michael Ryan, head of the WHO Health Emergency Project, said at a news conference: "even though the number of confirmed cases in other countries is small, the spread of the epidemic in some countries in sub-Saharan Africa continues to accelerate, which I think must be taken very seriously. Unfortunately, the epidemic in South Africa may only be a harbinger, and other countries in the African region may follow suit. "
