Dr Hilary Jones has warned that the effects of coming out of lockdown early could be 'disastrous' for the UK.
Speaking on Good Morning Britain, he said that the government shouldn't put more pressure on the NHS because people were 'getting bored'.
The comment comes after the UK saw a jump of 786 more deaths on Tuesday, April 7.
Talking to Piers Morgan and Susanna Reid, Dr Hilary said: "In the last 24 hours we saw the highest number of cases, the highest number of fatalities recorded so far.
"Although the growth is slowing, it's still growing. We're not at the peak yet.
"It was estimated that the peak would be Easter weekend, it could be a bit beyond that.
"It's certainly too early to talk about coming out of lockdown, in my opinion. We're getting more cases, we've got an exhausted NHS workforce.
"It would be completely unfair to expect them to carry on under the conditions they're currently working in and with the cases they've got by coming out of lockdown because people are just getting bored.
"We need take this seriously. We need people to hang in there a little bit longer.
"It's being reviewed all the time, and coming out of lockdown too early would be disastrous."
“In terms of the review, we are not at that stage yet," said Mr Raab.
“We will take any decision when the time is right, based on the facts and the scientific and medical advice.
“Our number one and overriding focus right now is on conveying the key message which is that everyone needs to keep adhering to this guidance.
“There is a long Easter bank holiday weekend coming up, warm weather and we understand people are making big sacrifices to follow this guidance.
“It is helping, it is contributing to our ability to tackle the coronavirus.
“The worst thing now would be to take our foot off the pedal, to ease up on that and risk losing the gains that have been made.
“It is absolutely critical that people keep up that discipline and the vast majority will. We hope everyone will follow that example.”
Good Morning Britain continues weekdays on ITV at 6am.
