Covid-19 Risk Assessment Week Ending 8 November 2021

The number of Covid-19 infected people in Bucks remains at a CRITICALLY HIGH level and BuDS urges everyone to STOP mixing with others, especially indoors, as much as possible. Read on for more.

Official data from last week shows that 1 in 45 people in Bucks may now be infected with Covid-19, especially children and young people. This is slightly reduced from last week but remains critically high. Hospitalisations are also up again with very little increase in the percentage of unvaccinated people. The Covid-19 pandemic is very definitely not over in Bucks and the risk of catching Covid-19 in Bucks has never been higher.



For some months now, England has seen a runaway Covid-19 pandemic among children and young people driven by the deliberate lack of Covid precautions in schools, colleges and universities. The pandemic among children and young people follows school holidays – the number of infected children and teenagers goes up during term time and falls back in holidays. The small drop in overall numbers of infected people in Bucks this week are simply due to the school half-term holidays.

But more recently, there has been another pandemic happening in England. The numbers of older people catching Covid has also started to steadily increase. This is because children and teenagers are bringing Covid home from school and giving it to their parents and grandparents. Vaccination of older groups is quite high, but nowhere near complete, and also the effect of vaccination wears off quite quickly. As a result, working-age and older people are now becoming seriously ill from Covid in larger and larger numbers. Hospitals and ambulance services are becoming overwhelmed, and sadly the number of deaths is also increasing. Unlike the Covid pandemic in schools, the pandemic in older people is showing no sign of reducing.

It is this ‘second pandemic’ in older people that the Government are now desperately trying to control by asking people to get booster vaccinations and by buying (but not yet actually prescribing) antiviral medicines.

Our advice to people is what it has always been: PROTECT YOURSELF by remaining ‘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.



Delta Plus (the new variant now widespread in Bucks) and Delta are airborne viruses – they travel mainly in the air breathed out by infected people. So, the three best ways to protect yourself are:

  1. Getting vaccinated against Covid-19 and getting booster doses as soon as you can, if you’re eligible. Vaccination will help you avoid getting seriously ill if you catch Delta Plus and booster jabs will refresh your protection.
  2. Making sure you are breathing clean fresh air, not air contaminated by other people’s breath. This means opening windows wide or being out of doors when you meet people who might be infected.
  3. Keeping well away from people who might be infected and breathing out the virus, by avoiding indoor places as much as possible and socially distancing even outdoors.

Wearing a loose cloth face-covering yourself, washing your hands and using hand sanitiser are still important but these precautions are not as effective against Delta and Delta Plus because the virus mainly travels by air.

Remember, it is not safe to catch Covid-19. Even if you are not very ill when you first catch it, there is a real clinical risk that you can develop long-term conditions afterward or even end up with organ or brain damage. Over a million people, both adults and children, are already disabled by or suffering symptoms of ‘Long Covid’.



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.



The UK Health Security Agency counts 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 9,516 infected people in Bucks. After revision of the test data by UKHSA, it turns out that the total was actually 9,324. That means last week the number of reported positive tests actually fell by 12% – we originally reported an 10% fall.

On the data we have from UKHSA, this week we calculate there are 7310 infected people in Bucks,1 which (taking last week’s revised total into account) means that the number of infected people in Bucks measured by UKHSA tests has fallen by a larger amount of 22% this week.



The UK Health Security Agency uses a range of surveys and test data every week to calculate the ‘R Rate’ for Covid-19.2 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 12,157 infected people in Bucks, and this week there are 10,894, a fall of around 10%. The R Rate is now calculated to be 1.2 in the South East by UKHSA, and still about 1.9 by the ONS.



Thirdly, using the maximum R Rate for the South East of England, including Bucks, we calculate that there were 13,534 infected people in Bucks last week, and now there are 12,041, a fall of around 11%.



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.3 Unfortunately, the survey results are slow to come out – the latest fully-comparable figures we have are for the week ending 25 October, 2 weeks ago. That data shows a significant rise (26.7%) in the number of infected people across the South East as a whole, which corresponds to and is much higher than the 11% rise we saw in reported positive tests in Bucks in that 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 slightly LOWER than last week but still CRITICALLY HIGH. Depending on the test data you use, the number of infected people has gone from between 9,500-13,500 to between 7,300-12,100. 1 in every 45 people in Bucks is infected with Covid-19.



Using the UKHSA max R Rate data, which we think this week is the most likely to be accurate,4 we have calculated that there are 12,041 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?5 – 22

How many infected people in Aylesbury?6 – 1,328

How many infected people in High Wycombe?7 – 2,656

How many infected people in Amersham?8 – 599

How many infected people in Chesham?9 – 591

How many infected people in Buckingham?10 – 332

How many infected people in Burnham?11 – 252

How many infected people (adults or children) in a large school?12 – 33

How many infected people in a busy town centre?13 – 221

How many infected people at a large public event?14 – 443

How many infected people in a busy shopping centre?15 – 22

How many infected people in a busy supermarket?16 – 7

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 45 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, 256 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 226 the week before, up 13%. Covid-19 continues to lead to the cancellation of operations and delays to other urgent hospital treatment for the residents of Bucks. Like every other ambulance service in England, South Central Ambulance Service, which covers Bucks, has declared an emergency several weeks in a row.



5 people were recorded as dying in Bucks last week within 28 days of a positive Covid-19 test, and 6 people were recorded as dying in Bucks last week within 60 days of a positive Covid-19 test. This brings the number of deaths in Bucks since the pandemic began to a shocking 1041 within 28 days or 1242 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.

 The ONS also measure the number of people dying of Covid-19 using death certificate data. This is the most reliable data by far, but publication is significantly delayed. The most recent comparative date we have is 21 October. On that date, the ONS found that 1253 people had died in Bucks of Covid-19 since the start of the pandemic, compared to 1030 within 28 days of a positive test and 1228 within 60 days of a positive test (as reported by the UKHSA). It is clear that the UKHSA reported figures massively understate the numbers of people dying, but this is not being picked up on by the media.



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

  • 40.0% of 12- to 15-year-olds in Bucks have had one dose, up 7% on last week. Almost none (0.2%) have had a second dose.
  • 67.2% of 16- & 17-year-olds in Bucks have had one dose, up 1% on last week. 12.5% have had two doses.
  • 84.7% of adults 18 to 70 in Bucks have had one dose, up 1% on last week. 80.7% have had two doses.
  • 96.6% of adults over 70 in Bucks have had one dose, almost unchanged on last week. 95.8% have had two doses.
  • Overall, 83.4% of the people on the NHS vaccine register in Bucks have had a first dose and 76.4% 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 17,823 12-15-year-olds, 4,657 16 & 17-year-olds, 57,645 adults under 70 and 2,625 adults over 70. In total, around 128,000 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.

This rolling average is the figure that we use in the post.
