British national David Good, who has been on holiday in South Africa for a fortnight and hopes to get home before the UK travel ban takes effect, says that Covid-19 is "very serious,". But Good adds: "we're always going to have new variants, so I don't know how we're going to keep locking down every time we find a new variant." South African tour operators are flooded with cancellations after countries follow Britain's decision to ban travel from the region over the discovery of a new coronavirus variant. SOUNDBITE
