SA's Rugby Sevens coach Neil Powell is among four South Africans who have tested positive for Covid on arrival in Japan, including three SA Under-23 football members. The entire Under-23 squad is in quarantine after two players, Thabiso Monyane and Kamohelo Mahlatsi, as well as video analyst Mario Masha tested positive for Covid-19. Team South Africa confirmed the news in a statement on Sunday, saying their officials and management followed all relevant Olympic Playbook rules, protocols and procedures throughout the pre-Games and Games arrival routines. They added that the rest of the team had tested negative twice and was closely following all the recommendations of the local health authorities. According to the Guardian UK, the three South Africa football squad members were the first reported cases found on arrival at the Olympic Village, ahead of the Games' start this Friday. "Every member of Team South Africa required full medical clearance as an eligibility criteria," said Team SA's Chief Medical Officer Dr Phatho Zondi. "The timing of the positive results suggests that the PCR test in these individuals was done during the incubation period of the infection, which is how they could be negative in South Africa and then positive in Japan. Infection rates are rising among the general population of Tokyo, topping 1,000 new cases for four consecutive days. Polls show many Japanese people oppose holding the Games with the influx of overseas visitors it entails. In total, organisers on Sunday reported 10 new cases connected to the Olympics including media, contractors and other personnel. That compares with 15 new cases on Saturday.
