is calling on the public to remain vigilant against Covid by “taking time out” when they get the virus to reduce transmission as the wave of summer cases continues.figures for the week to Sunday 30 June, suggest that the summer wave may have just peaked but that cases remain higher than they have been for all but one of the past 18 weeks.
However, this was still considerably higher than the 10.0 per cent positivity rate recorded just ten days earlier, in the week to 20 June.Scientists said that data based on positivity rates among people suspected of having Covid is much less accurate than testing a large cross section of the general public at random – but that they do give an indication of trends.
“The frustration is that in the absence of widespread testing we don’t have an accurate picture of the current level of infection. This is dangerous as it means that we are completely blind to the spread of infection making it difficult to protect the most vulnerable.
