JOHANNESBURG – South Africa says it has a backlog of nearly 100,000 unprocessed tests for the coronavirus, a striking example of the painful shortage of testing kits and reagents across Africa as cases steadily rise. “This challenge is caused by the limited availability of test kits globally,” the health ministry said in a statement overnight putting the backlog at 96,480 as of Monday.
Priority is given to processing tests from patients admitted to hospitals and health workers, it said. South Africa has conducted more tests for the virus than any other country in Africa — more than 655,000 — and has the most confirmed cases with 27,403.
