JOHANNESBURG — Africa’s reported cases of COVID-19 have surpassed 300,000 as the spread of the disease quickens across the continent. The Africa Center for Disease Control and Prevention said Monday the continent now has 306,567 confirmed cases, including 8,115 deaths and 146,212 recoveries. It took more than 90 days for Africa’s 54 countries to reach 100,000 cases, 19 days to reach 200,000 and now 12 days to go above 300,000. The actual number of cases is believed to be much higher because testing across the continent is low.

South Africa, with 97,302 cases, accounts for nearly 1/3 of the continent’s total cases. The country had initially hoped it could control the disease through testing and tracing. But despite conducting more than 1.3 million tests, the highest number in Africa, it currently takes an average of 12 days to get results, which medical experts say is much too long to do any effective tracking and quarantining.
