expert reaction to latest daily case numbers

A comment from Professor Paul Hunter and Dr Simon Clarke on the latest figures on the DHSC COVID-19 Dashboard.


Dr Simon Clarke, Associate Professor in Cellular Microbiology at the University of Reading, said:

“It is probably premature to suggest that we are seeing a levelling-off of infections based on today’s data. Numbers of infections over the past year have shown big rises and falls much like today, and so it’s wise to look at the trends rather than getting too excited about daily numbers. 

“We have not yet seen the effect of lifting of final restrictions on 19th July on numbers, nor have we yet seen how school summer holidays may take some heat out of the infection numbers. However, any good news about lower cases as schools close can expect to be reversed come September. 

“It remains the case that mixing of people will remain the most significant driver of infection numbers, while vaccinations will have the largest effect to reduce those numbers.  Of course, the vaccines are not 100% effective at reducing transmission, and the virus cannot spread at all without social interactions, so ongoing care needs to be taken while numbers are still high.”


Prof Paul Hunter, Professor in Medicine, The Norwich School of Medicine, University of East Anglia, said:

“Today’s reported case numbers 39,906 are the first time that case number reports are lower than they were on the same day in the previous week since early May. They represent a 18% drop. Also the week on week percentage increase in cases has fallen from a peak of 43% last Sunday to just 24% today. But it is still too early to see any impact of the relaxations of Monday 19th and some of the reduction in cases will be because of many children no longer being tested as regularly now schools are closed. 

“I would caution that this may just be a temporary slowing in reports before we start to see a return to exponential growth towards the end of next week as a result of the ending of restrictions last week. We will start to have some idea towards the end of next week, but it won’t be until the 9th August (3 weeks after “Freedom Day” before we know for certain.

“But there are some positive signs. If you look at the course of the Delta epidemic from early May it was clear that the rate of increase in cases was already slowing by June. But there was a significant acceleration in new cases about 8 to 10 days after the first England game in the Euros. There was also a subsequent acceleration around the same time after the quarter finals. But after both events the increase started slowing fairly soon after that despite the fact that the games were continuing. Also, in Scotland case numbers started to fall about 11 days after they left the Championships and case numbers have continued to fall since.

“If such a perturbation as the Euros caused only a temporary acceleration in the increase in case numbers despite games continuing this may bode well for the impact of the 19th July, it could suggest we will see only a short-term boost towards the end of next week followed by slowing or even a decline in the days following. Time will tell.”
