South Africa Leads Global Research on COVID's Effect on Athletes Marize de Klerk PRETORIA, SOUTH AFRICA - Organizers of next year's rescheduled Tokyo Olympics will have measures in place to limit the spread of the coronavirus. However, little is known about how the virus affects the long-term health of those who were already infected, including athletes. South African researchers are leading an international effort to try to find answers. South African Olympic hurdler Wenda Nel is grateful to be back on track for next year's rescheduled Tokyo Olympics after recovering from COVID-19, the disease caused by the coronavirus. "It was about two to four weeks that I've took it very slowly with the training. Checked my heart rate every training session. Just monitor that. And from there I actually went into full program. And I feel stronger '¦ fit '¦ and actually fully recovered right now," she said. .
