A Cape Town mother poured her heart out on social media on Wednesday about the importance of self-isolation in curbing the spread of Covid-19.Angela Fourie's daughter was born with biliary atresia which is a rare disease of the liver and bile ducts.At nine months, Olivia had to undergo a liver transplant but fortunately her father was a perfect genetic match."The operation was so successful that she is on a minimum dose of immune suppression. She also has normal blood results and liver function," said Fourie.However, she still worries, and the outbreak of the Covid-19 puts her daughter at risk."The whole point of sharing Olivia's story is to illustrate that although you might not be at risk, staying at home and self-isolating is contributing to containing the virus. "There are a lot of healthy people who can recover but a child like mine who is immune-compromised would take a long time to recover or not even recover at all," she told News24.Despite her concerns, Fourie is grateful for the people who are complying with the regulations."This thing belongs to everybody, this virus has no boundaries. You have to do this for me and my daughter and all the other people at risk."
