weeks ago. as you can see from this graph there has been a huge spike in cases there. they ve jumped from less than 500 a day in november to to 38,000 on sunday. that includes south african president cyril ramaphosa, who tweeted his thanks for good wishes after testing positive for covid 19. and he gave a message: don t let your guard down. do everything you can and need to, to stay safe, beginning with vaccination. let s hear from a vaccines professor in south africa. we are finding a significant number of break through infections, as well as re infections in individuals who were previously infected with other variants. that being said, what we ve also observed is a significant coupling of the case rate community and hospitalisation and death rate, with hospitalisation and death rate much more subdued compared with what the case rate was during the course of the previous waves at the same point. so, we re seeing this sort of uncoupling that s emerging which appears to be good news.
