Vallance and Whitty give their warnings on Covid19 outbreak

Speaking at Downing Street alongside chief medical adviser, Prof Chris Whitty, along with Sir Patrick Vallance stressed the figures given were not a prediction, but said:

“At the moment we think the epidemic is doubling roughly every seven days.

If, and that’s quite a big if, but if that continues unabated, and this grows, doubling every seven days… if that continued you would end up with something like 50,000 cases in the middle of October per day.

Fifty-thousand cases per day would be expected to lead a month later, so the middle of November say, to 200-plus deaths per day.

The challenge, therefore, is to make sure the doubling time does not stay at seven days.

That requires speed, it requires action and it requires enough in order to be able to bring that down.”

Graphic

Prof Whitty added that if cases continued to double every seven days as Sir Patrick had set out, then the UK could “quickly move from really quite small numbers to really very large numbers because of that exponential process”.

“So we have, in a bad sense, literally turned a corner, although only relatively recently.”

They also said in their statement:

  • The rising case numbers could not be blamed on an increase in testing as there is also an “increase in positivity of the tests done”
  • Around 70,000 people in the UK are estimated to currently have the disease – and about 6,000 per day are catching it (based on an ONS study)
  • Less than 8% of the population has been infected, although the figure could be as high as 17% in London
  • The rising transmission is a “six-month problem that we have to deal with collectively”
  • The virus is not milder now than in April, despite claims to the contrary
  • It is possible “that some vaccine could be available before the end of the year in small amounts for certain groups” but “the first half of next year” is much more likely
