Again, not to start a new thread:
Cape Town – Antigen tests for coronavirus detection will be rolled out to all ports of entry with immediate effect, the government said on Thursday.
On arrival, a traveller will be screened for symptoms and sent for testing should they not have a certified polymerase chain reaction (PCR) test result. The test will be conducted at a fee of about R150-R170 and will be paid by the traveller.
Anyone who is red-flagged for showing symptoms of Covid-19 may still be quarantined, even with a negative antigen test.
