Authorities in South Africa's Western Cape province have expressed deep concern about a sharp jump in Covid-19 cases.
The virus is showing signs of a resurgence in parts of South Africa – the most badly affected country on the continent.
After a long lull, infection rates are beginning to rise in some areas, particularly along the country’s southern coastline.
Doctors in Cape Town and in Port Elizabeth are reporting a spike in hospital admissions.
One provincial leader described the increase as staggering and said the virus was spreading widely, not just in a handful of hotspots.
Concerns about a second wave are coinciding with nationwide protest action over low pay by community health workers – key figures in South Africa’s fight to contain the virus.
The country is now heading towards its main summer holiday season, a time when millions of people travel.
With the economy in deep trouble, the government is thought to be reluctant to reimpose tough lockdown restrictions.
