However he at this time mentioned he could be “pleased to be proved incorrect” after a gradual decline in instances from 54,674 on 17 July to 24,950 on Monday.
The “sudden” fall in instances in latest days could also be linked to the top of the Euro 2020 soccer event on 11 July and the arrival of heatwave climate, each of which have led to a discount in folks gathering indoors, he mentioned.
However he cautioned that this didn’t imply the newest wave of coronavirus is over.
“I feel it’s too early to inform,” the epidemiologist informed BBC Radio 4’s As we speak programme. “The reductions we’re seeing in the mean time occurred earlier than the unlocking came about and we gained’t see for a number of extra weeks what the impact of the unlocking is.
“I’m pleased to be proved incorrect if it’s incorrect in the suitable route. If case numbers keep low that shall be actually excellent news.
“However I feel we do need to be barely cautious. I feel in all probability infections locally are plateauing, however we’ll see that later this week with the newest Workplace of Nationwide Statistics an infection survey.
“Positivity – the proportion of instances which take a look at optimistic – solely began happening very, very barely on 21 July.
“We’ve got to observe various completely different indicators to see what’s occurring, however it’s going to in all probability take a number of extra weeks for us to see the impact of unlocking.”
Prof Ferguson mentioned that the essential charge of transmission – often known as R – could be as excessive as three or 4 if it weren’t for the excessive charge of vaccination within the UK, however is presently in all probability round one due to widespread immunity.
“The important thing situation is what impact will 19 July have had,” he mentioned. “Faculty closure and holidays cut back transmission usually, however the rest will improve it.
“For the time being, we will’t choose precisely how these issues are going to steadiness out and we haven’t seen the impact of these in any of the info up to now.”
Prof Ferguson rejected strategies that the obvious fall in instances was purely all the way down to a discount in testing following the closure of faculties, or to folks dodging assessments within the hope of having the ability to go away on holidays within the coming weeks.
He mentioned he expects a “clear plateau” in optimistic instances to emerge this week, following the sudden fall of the previous few days.

By the autumn, Prof Ferguson urged that the pandemic might successfully be over within the UK.
“We’ll have the ability to inform actually later this week after which subsequent week whether or not we see hospitalisations – that are nonetheless rising in the mean time – begin to decline,” he mentioned. “That will give us extra confidence that we actually have seen a peak – perhaps not the height, however a peak – in the mean time.
“We have to stay cautious. There may be the potential of fairly a considerable improve involved charges once more, significantly if the climate stays much less nice and faculties reopen in September.
“We’re not utterly out of the woods however the equation has basically modified. The impact of vaccines has been enormous in lowering the chance of hospitalisation and loss of life.
“I feel I’m optimistic that by late September, October time we shall be wanting again at a lot of the pandemic. We’ll nonetheless have Covid with us, we’ll nonetheless have folks dying from Covid, however we may have the majority of the pandemic behind us.
“The upper we will get vaccination protection the higher – that may defend folks and cut back transmission. However there’s going to be remaining uncertainty till the autumn.”
