Coronavirus: Plea from third SA victim's family

A family man from South Australia's Riverland region has become the third person to die from COVID-19 in the state.

Malcolm Todd was travelling to the Barossa Valley with his wife of 32 years, Sandi, to see their son who had just returned home from Switzerland.

It is believed the 76-year-old Barmera local contracted the virus when he and his wife shared dinner at Lyndoch Hill winery, a location now linked to a cluster of confirmed cases in the region.

Mrs Todd also contracted COVID-19 and was forced into isolation, unable to see her ailing husband.

After weeks of fighting for his life, doctors knew his time was limited and organised a video call last night to allow Mrs Todd to say her final goodbye.

"We ask people to do what's being asked of them - to stay home and stay safe, and not spread this disease," Mrs Todd said in a statement.

"Because every risk they take can put people at risk and put people through what we are going through."

The Barossa cluster now stands at 38 infections, with nine confirmed cases linked to a group of Swiss tourists and 29 linked to a group of visitors from the US.

Previous deaths in South Australia have been Adelaide grandfather Frank Ferraro on Monday and a 62-year-old Adelaide woman yesterday.
