Changes to the way data is recorded is causing confusion in figures for the second day running.

Yesterday a warning on the government dashboard read: "The introduction of a new system disrupted the removal of cases where a positive rapid lateral flow test was followed by all negative polymerase chain reaction (PCR) tests taken within three days.

"These 4,776 cases have now been removed. Newly-reported cases for the UK and England were unaffected. Historical published date totals have not been changed."

However, it warned that Tuesday's data would show "significantly lower numbers or zero" at regional and local authority level, and "do not reflect the actual number of new cases reported on that date."

Now it states a further 561 cases have been removed, with UK and England numbers of newly reported cases now adjusted so they "correctly reflect new cases reported."

It adds that the issue is due to be ongoing over the next few days.

With all that in mind, today's update shows a rise of seven new cases for Cornwall and the Isles of Scilly in the last 24 hours, following apparently no rise at all yesterday, while the overall total has risen to 14,286 since the start of the pandemic, after falling to 14,279 cases on Tuesday from a previous 14,319.

Weekly cases, which are on a delay, appear to have fallen by seven to 28 in the seven days leading up to May 13 – the most recent five days not shown due to incomplete data – from 33 reported yesterday.

The weekly case rate has fallen to an average 4.9 cases per 100,000 people, from 5.8 cases yesterday and 7.0 on Monday.

The number of people testing positive for coronavirus in the UK increased by 2,696 in 24 hours. This takes the total to 4,452,527 nationally since the start of the pandemic.

As of last Friday the NHS England hospital daily figures are being published every weekday, rather than every day.

Local daily figures from the most recent update showed there had been no further deaths recorded since April 23 at the Royal Cornwall Hospitals Trust.

The total number of Covid-related deaths at the Royal Cornwall Hospitals Trust remains at 202 while at the Cornwall Partnership NHS Trust it remains at 62.

The combined number of Covid-19 deaths in total in Cornwall’s hospitals since the start of the pandemic stands at 264.

The Government dashboard reports that the overall number of deaths in Cornwall – including deaths in care homes and other settings – remains at 469 in the 28 days after a positive test.

The number of deaths simply with Covid-19 on the death certificate also remains at 570 in the most recent data available. This figure is updated weekly on a Tuesday and included no new deaths in the week leading up to Friday, May 7, the most recent date given.

The overall UK figures show three more people to have died within 28 days of their first positive test result. This takes the total UK deaths within 28 days to 127,694. These figures include people in care home and other settings.

Up to the end of Tuesday, May 18 a total of 36,985,505 people in the UK have had received their first Covid-19 vaccination dose, while 20,870,453 people have had their second dose.
