There have been 81,294 confirmed cases of Covid-19 in Scotland and 3,280 people have died following a positive test for the virus, according to Scottish government figures.
This page is updated regularly and analyses the key figures for the coronavirus outbreak in Scotland.
Figures updated at 14:00 on 15 November 2020.
Over the past seven days there have been 7,851 cases detected following a test, with 1,159 confirmed on Sunday.
This next chart shows the number of daily confirmed cases after an NHS Scotland or UK government test since 1 August, along with a seven-day average.
The actual number of people infected since February will be far higher than the overall confirmed cases figure, as most people who had Covid-19 during the peak of the outbreak were not tested.
Scotland’s “second wave” has seen a much bigger surge in the number of cases because many more people are being tested.
The weekly number of positive tests per 100,000 people in each of Scotland’s 32 local authorities is now a key indicator of which Covid level a council area will be placed in.
The Scottish government works to a system of thresholds, while also considering other indicators such as hospital admissions when reviewing the levels.
The number of positive cases in each local authority is published daily by Public Health Scotland.
The most recent data often underestimates the number of positive tests as there are sometimes delays before results are recorded, so this chart uses figures from four days ago.
It is also possible to see rates for the past seven days by NHS health board.
Over the course of the outbreak, the highest number of cumulative cases has been in NHS Greater Glasgow and Clyde, reflecting the fact it is the most populous part of Scotland.
The first coronavirus death in Scotland was reported by NHS Lothian on 13 March and the number of daily deaths peaked on 15 April when 84 were reported.
Over the summer, Scotland went for a long period when there were no deaths following a positive test for Covid-19, but the rate of new deaths is rising again.
There are three ways to measure deaths from Covid-19.
The Scottish government’s daily announcement counts deaths within 28 days of a positive test for Covid-19, whereas the National Records of Scotland (NRS) counts all death certificates that mention Covid-19, even if the person has not been tested for the virus.
The NRS also publishes monthly data on excess deaths in 2020, compared with a five-year average.
At its peak, the coronavirus outbreak created a huge load on Scotland’s hospitals, with 1,520 Covid patients being treated across the country on 20 April.
The number of people in hospital is currently far lower than that, but has been rising steadily for a few weeks.
This chart shows the numbers of patients in Scottish hospitals since 11 September.
It is hard to compare the numbers in hospital now with figures over the summer as the Scottish government has recently changed the way it counts them.
From 11 September, only patients who test positive during their current stay in hospital, or in the two weeks before their admission, are included in the numbers.
They will also no longer be classified as Covid patients after 28 days in hospital or 28 days after their positive test, whichever is later.
This change led to a big drop in the number of people classified as Covid patients.
The number of hospital patients being treated in intensive care is also down from a peak of 208 in early April, but is on the rise again.
The World Health Organisation (WHO) says the percentage of positive test results is a key measure when assessing the status of a Covid-19 outbreak within a country.
The organisation has stated that if less than 5% of samples from a comprehensive testing system return a positive result over two weeks then it is one indication an epidemic is under control.
Other indications include a continuous decline in hospital admissions and a decline in the number of new deaths over at least three weeks.
This chart shows the “positivity rate” in Scotland since 18 August.
The Scottish government changed the way it measures this rate on 19 October.
Previously, the government calculated it by dividing the number of positive cases with the number of newly-tested individuals each day.
However, it now calculates the rate using the number of positive tests reported each day.
The Scottish government said it changed the method to bring it into line with the WHO’s criteria, and because the previous measure was “likely to over-estimate the positivity rate” as more people were repeatedly tested.
Data on the number of positive tests each day (rather than positive cases) is only available from 18 August.
The R number, or reproduction number, is a way of rating a disease’s ability to spread. It is the average number of people that one infected person will pass the virus on to.
If the reproduction number is higher than one, then the number of cases increases exponentially.
The Scottish government has been monitoring the estimated R number in Scotland since the start of the outbreak.
