Scientists warn, however, that lower severity of cases is not fully understood and may not occur elsewhere

Scientists, however, cautioned that the reasons less severe cases were being seen was not fully understood and that South Africa’s experience – with a young population – might not translate into how other countries experience Omicron. While evidence from South Africa about the virulence of the Omicron variant is being studied around the world – including in the UK – the NICD’s Michelle Groome warned that the South African data could not necessarily be extrapolated to other countries with different population profiles.
Against the more optimistic claims that the fourth wave of Covid in South Africa might be less severe, in the past week there has been an uptick, so far small, in hospitalisations and deaths in South Africa’s hospitals.The claims about virulence came as some South African experts were claiming a “sustained drop” of new Covid cases.
