Angola confirms first cases as coronavirus spreads over Africa

* Angola confirms first two COVID-19 cases

* Mauritius records first death as numbers rise

* Confirmed cases in South Africa jump

* Africa now has more than 830 cases

NAIROBI/JOHANNESBURG, March 21 (Reuters) - Angola on Saturday confirmed its first two cases of coronavirus, while Mauritius recorded its first death as the virus spreads across Africa.

The continent has been slower to feel the impact than Asia or Europe, and most of its reported cases have been foreigners or people who have returned from abroad.

But confirmed infections have started to accelerate, with more than 830 across Africa, according to a Reuters tally, and concerns are growing about its ability to handle a surge in cases without the depth of medical facilities available in more developed economies.

Angola's first cases were two male Angolan residents who flew back from Portugal on March 17 and 18, Health minister Silvia Lutucuta told a briefing.

Zimbabwe reported its first case on Friday, and a second on Saturday, while the island of Mauritius, with 14 cases, reported its first death, a person who had travelled from Belgium via Dubai.

Many African countries have already shut borders, closed schools and universities and barred large public gatherings to curb the spread of the virus, which has infected over 250,000 people around the world and claimed more than 10,000 lives.

South Africa, which has the most cases in sub-Saharan Africa, confirmed 38 news cases, taking its total to 240.

Africa’s most populous country, Nigeria, confirmed 10 new cases including the first three in the capital Abuja, bringing its total to 22.
