The general secretary of the SA Federation of Trade Unions (Saftu), Zwelinzima Vavi, has tested positive for Covid-19.
Vavi told eNCA on Thursday he had no idea how he became exposed to the virus.
“All I had was a flu from Friday and it got worse by Saturday and Sunday and yesterday I went to test, just to be on the safe side, not that I had any of the signs ...” he said.
“The last thing I was expecting was to test positive but there you are. And it shows you the reason this thing is so dangerous is that you take it lightly.
“Even now, I feel absolutely fine and better than any other day of the past five days and (yet) they called to say 'you are positive, you must go to self-isolation'," he said.
Vavi revealed he had been homebound since the lockdown came into effect last Friday.
The last meeting he attended had been a political and ideological meeting of Saftu, two days before the lockdown, he said.
He also said he had gone for a coronavirus test on Saturday but was turned away because he did not
have a fever.
