Covid-19 Risk Assessment Week Ending 25th October 2021

The number of infected people in Bucks has jumped to a CRITICALLY HIGH level. Official data from last week shows that more than 1 in 48 people in Bucks is now infected with Covid-19, especially children and young people. Deaths and hospitalisations are also up sharply, with vaccinations (except of children) virtually at a standstill. BuDS urges everyone to STOP mixing with others, especially indoors, as much as possible. The risk of catching Covid-19 in Bucks has never been higher. Read on for more details.



England is in the grip of a runaway Covid-19 pandemic driven mostly by uncontrolled virus transmission among children and young people. While these younger people are less badly affected by Covid-19, they are of course passing on the virus to their parents and other relatives and people they meet. So, the numbers of older people with Covid-19, who are more likely to need hospital treatment, are now sharply increasing. The increasing numbers of Covid-19 patients, together with the growth in normal winter diseases, means there is a crisis in the NHS in England, although the Government stubbornly deny this.


Vaccination *is* slowing the spread of Covid-19. Without vaccination, the NHS would have been overwhelmed weeks ago. But there are still many millions of children and adults in the UK who are not vaccinated or who cannot be vaccinated, and these unvaccinated people do not have any protection against Covid-19. Also, the amount of protection given by the vaccine wears off quite quickly – after 5 months, your protection has roughly halved.1 This is why the Government is starting to slowly offer third vaccination doses (often called boosters), to keep protection levels high. But the booster programme is happening much too slowly to stop many tens of thousands of vaccinated people getting seriously ill and dying from Covid-19.



The Government announced earlier this week that, despite rising infections, hospitalisations, and deaths, they do not intend to bring back any mandatory precautions to help contain Covid-19 in England. The Government seem content for very large numbers of people to be seriously ill with Covid-19 and to die of Covid-19 rather than making any effort to save people’s lives and health which would ‘interfere with the freedom to live normally’.

The number of people in the Bucks community that you could catch Covid-19 from is CRITICALLY HIGH. 1 in 48 people in Bucks has Covid-19. The risk of catching Covid-19 in Bucks has never been higher since the January peak during lockdown. If you don’t want to catch Covid-19, it is CRITICALLY ESSENTIAL that you continue to be ‘Covid-Careful’.

Covid-Careful doesn’t mean shielding or complete self-isolation – meeting friends and family is vital for mental health, and it is still safe to meet OUTDOORS if you take sensible precautions (read our article or watch our video to learn more). But EVERYONE now should be meeting as few people outside their household as possible, and avoiding crowds, events and indoor places like shops, restaurants and pubs.



The Delta variant of Covid-19 is airborne and loose cloth masks are not much protection against it. With very high infection rates as we have at the moment, the only way to avoid catching Delta is to stay away from the breath of infected people.

You do this by avoiding places where there are lots of people and keeping your distance from others. If you do meet others, do so only outside or in very well-ventilated places. These precautions are much more important than wearing a cloth face mask or washing your hands.

BuDS strongly recommends that you STAY OUT of indoor places as much as you can. This means working from home if you can, not going shopping if you can avoid it, and absolutely not going to meetings, theatres, cinemas, pubs and restaurants. Your chance of catching Covid-19 if you try to live a ‘normal life’ is now critically high.

You should also avoid crowds at all costs, even out of doors. Crowds generate clouds of virus in the air which can infect large numbers of people.



It is highly likely that children and teenagers attending school and college will bring Covid-19 home with them at some point. If your household includes a higher-risk person, e.g. someone who had formerly been told to shield or an older person, then now is the time to take precautions. The Department for Education has confirmed after a legal challenge that children can be kept off school to protect a vulnerable person, so please think about doing this if necessary. Contact BuDS if you’d like more information.

You catch Covid-19 from other infected people, so knowing how many infected people are around in your community is the most important fact when looking at risk. BuDS uses 4 separate sets of official data to make sure we can give you the best and most balanced picture of the risk from Covid-19 in Bucks. We are not trying to make precise mathematical calculations but assess whether the number of infected people in the local community is going up or down.



Public Health England count the number of people who test positive for Covid-19 using either a laboratory PCR test or a lateral-flow test kit later confirmed by a PCR test. BuDS adds together the daily positive test totals over the last two weeks, because people generally have Covid-19 and are infectious for about two weeks. This gives us a total number of people who have tested positive for Covid-19 and are still infectious. This total still underestimates the true number of infected people in the community, because lots of people who have Covid-19 don’t get tested or don’t report a positive test. So, BuDS increases the number of people testing positive to try to take account of the people who are positive but don’t get tested or report a positive test.

Last week, after making the calculations shown above, we said there were 8977 infected people in Bucks. After revision of the test data by PHE, it turns out that the total was actually 9476. That means last week the number of reported positive tests actually rose by 27%.

On the data we have from PHE, this week we calculate there are 11444 infected people in Bucks,2 which (taking last week’s revised total into account) means that the number of infected people in Bucks measured by PHE tests has again risen significantly by 21% this week.



Public Health England use a range of surveys and test data every week to calculate the ‘R Rate’ for Covid-19.3 The R-rate measures how quickly the number of people infected with Covid-19 is growing or shrinking. Using the average R Rate for the South-East of England, including Bucks, we calculate that last week there were 7619 infected people in Bucks, and this week there are 9476, a large rise of around 24%. The R Rate is still calculated to be 1 in the South East by PHE, and about 1.3 by the ONS – the rise we are seeing suggests that the ONS calculation is more accurate.  



Thirdly, using the maximum R Rate for the South East of England, including Bucks, we calculate that there were 8498 infected people in Bucks last week, and now there are 10425, a large rise of around 23%.



The Office for National Statistics test a random sample of 50,000 people across the UK every week, whether they are ill or not, to see how many have Covid-19. This Infection Survey is the most reliable way of estimating how many people have Covid-19, because it doesn’t rely on people choosing to get a test or report a positive result.4 Unfortunately, the survey results are slow to come out – the latest fully-comparable figures we have are for the week ending 11 October, 2 weeks ago. That data shows a rise (3.7%) in the number of infected people across the South East as a whole, which corresponds to but is much lower than the 20% rise we saw in reported positive tests in Bucks in that week. This is significantly out of trend, and suggests that the data may be revised next week. The ONS still finds more infected people in Bucks than is shown by reported positive tests.



Looking at all the data, it is clear that the risk from Covid-19 in Bucks is HIGHER than last week. Depending on the test data you use, the number of infected people has gone from between 7600-9000 to between 9500-11500. 1 in every 48 people in Bucks is infected with Covid-19, and the risk of meeting one of those infected people in the community is CRITICALLY HIGH.



Using the PHE test data, which we think this week is the most likely to be accurate,5 we have calculated that there are 11444 people infected with Covid-19 in Bucks this week. At least some of these infected people in Bucks will be showing symptoms and self-isolating or been told to self-isolate by Track and Trace. Some may be in hospital. However, for the purposes of calculating risk, we will take the ‘worst case’ scenario and assume that every infected person is still out in the community potentially able to infect you. How likely are you to meet them?

How many infected people in every 1000?6 – 21

How many infected people in Aylesbury?7 – 1262

How many infected people in High Wycombe?8 – 2525

How many infected people in Amersham?9 – 570

How many infected people in Chesham?10 – 562

How many infected people in Buckingham?11 – 316

How many infected people in Burnham?12 – 239

How many infected people (adults or children) in a large school13 – 32

How many infected people in a busy town centre?14 – 210

How many infected people at a large public event?15 – 421

How many infected people in a busy shopping centre?16 – 21

How many infected people in a busy supermarket?17 – 6

Remember, people infected with Covid-19 move about. The figures above show a theoretical number based on population or crowd size to help you get an idea of the likely number. Also, you don’t necessarily have to meet 48 people to meet one with Covid-19. The first person you see in the street or supermarket might be the one person with Covid-19.



The pressure from Covid-19 on Bucks hospitals has risen again this week, remaining HIGH. Last week, according to NHS data, 178 people were admitted to Bucks hospitals for the first time with symptoms of Covid-19 or were admitted to hospital for other reasons and found to have Covid-19 when tested in the hospital, up from 150 the week before. Covid-19 continues to lead to the cancellation of operations and delays to other urgent hospital treatment for the residents of Bucks.



6 person were recorded as dying in Bucks last week within both 28 and 60 days of a positive Covid-19 test. This brings the number of deaths in Bucks since the pandemic began to a shocking 1029 within 28 days or 1227 within 60 days. To put that in perspective, 100 times more people have died of Covid-19 in Bucks than people killed in road traffic accidents in an average year.

Historically, this 28 and 60-day fatality data underestimates the number of people dying of Covid-19, but the true total will not be known for months until finalised death certificate data is available.



The vaccination programme in Bucks, other than for children, is pretty much at a standstill.  

  • 32.7% of 12- to 15-year-olds in Bucks have had one dose, up 10% on last week. Almost none (0.4%) have had a second dose.
  • 66.9% of 16- & 17-year-olds in Bucks have had one dose, up only 1% on last week.  20.5% have had two doses.
  • 83.9% of adults 18 to 70 in Bucks have had one dose, almost unchanged compared to last week. 79.8% have had two doses.
  • 96.0% of adults over 70 in Bucks have had one dose, almost unchanged on last week. 95.0% have had two doses.
  • Overall, 82.3% of the people on the NHS vaccine register in Bucks have had a first dose and 75.8% have had a second dose.

This may sound reassuring, but very large numbers of people in Bucks have still to receive any vaccine or cannot be vaccinated for clinical reasons. They include 19,978 12-15-year-olds, 4,576 16 & 17-year olds, 61,016 adults under 70 and 3,097 adults over 70. In total, around 133,000 people in Bucks of all ages have not yet received even a single dose of vaccine.



The key message for EVERYONE hasn’t changed: this is a time to you to ACT TO PROTECT YOURSELF from both Covid-19 and Long Covid by being Covid-Careful.
