1 in 152 people in England likely now infected. Covid levels rise nearly a fifth this week. High risk of meeting a Covid infected person.

Covid-19 Risk Assessment: Week Ending 21 September 2025

Covid infection levels in England have again risen sharply over the last week, as have other Covid measures. Infection levels are around a fifth higher, and the overall risk level remains High. It is clear that the next Covid wave is upon us, and we urge everyone take precautions against catching this dangerous virus. Now is also the time to get your Covid boosters (if available to you) as quickly as possible.

As of 21 September, around 1 in every 152 people in England were infected. This means that the risk of encountering an infected person in most indoor places is now High. Unless the indoor air is fresh, or filtered/purified, good quality PPE respiratory masks are needed to protect yourself. If you need any advice about this, please do ask.

Covid Symptoms Around You

You will probably have noticed that many people around you are starting to go down with flu-like symptoms. The official NHS data shows that there is very little influenza or common cold virus circulating at present. If people are showing signs of a respiratory virus such as fever, coughing, sore throat, headache, exhaustion, etc, at the moment it is much more likely to be Covid than any other respiratory virus. We urge everyone experiencing these symptoms to test themselves several times for Covid. If the test is positive, please notify your GP surgery as this could be very important in your future health treatment if you develop a post-Covid condition.

If you or someone you have met does have symptoms of Covid/a respiratory virus, please do the decent, patriotic thing and keep it to yourself. Unless you are absolutely unable to do so, please isolate until your symptoms have been gone for a couple of days. If you can’t isolate, wear a tight-fitting PPE respiratory mask (FFP2/FFP3) whenever you are in contact with other people. The mask will do you no harm, but will contain the virus in your breath and help prevent you infecting other people. This could easily save a life if you stop the virus getting to a clinically vulnerable person.

Some people on social media are saying that the UK has always had waves of flu-like illness at around this time, and they refer to “seasonal illnesses” as if there was no need for people to worry. This is inaccurate. Firstly, pre-pandemic these seasonal flu and colds peaked typically between November and February. This is September, and seasonal colds and flu have not even started to ramp up yet. Secondly, Covid has never been a winter virus. In 2024, the three peaks of Covid were in January, July, and October. The UK experiences a Covid wave when a new variant of the virus comes along which can cut through pre-existing immunity. This is pandemic virus behaviour, not a seasonal illness pattern at all.

Covid Activates Dormant Cancer

Recent research has proven that Covid can activate dormant cancer cells and cause cancers that in are in remission to start growing again. This is a medical fact, not scaremongering. If you are a cancer survivor, or you know someone who is, please take extra care not to catch Covid as it represents a particularly high risk to your health. Please reshare this warning with your own networks if you can.

Get Boosted

The NHS has begun its 2025 Autumn Covid booster campaign. If you are eligible, you can book an appointment online now, or you can wait to be called by your GP surgery. We strongly recommend that you book an appointment as soon as possible, so that you can boost your immunity before the wave grows further. Remember, vaccination boosters are essential to reduce your risk of serious illness and hospitalisation when you catch Covid. They do not significantly reduce your risk of catching the virus altogether. Also, boosters do not prevent you from becoming quite significantly ill at home. Taking precautions against catching Covid is still sensible, even once you are fully boosted.

The NHS has decided to severely restrict the people who are eligible for Covid booster vaccines this autumn. Those who are eligible are: people aged 75 years and over, those in older adult care homes, and those aged 6 months and over who are clinically immunosuppressed. Ridiculously, health and care staff, and relatives and/or household members of eligible people are not eligible themselves. Private Covid boosters are widely available, but the cost is typically around £100 per person.

Risk Analysis

BuDS continues to encourage everyone to take the level of Covid and other precautions that feels right for them, bearing in mind their own personal circumstances and the need to protect others. Our role is to give you the information to help you make informed decisions, and we will do so in this post. Remember, precautions against Covid will also help protect against all respiratory viruses including flu, norovirus, bird flu and measles.

Risk on journeys is calculated assuming that people visit several places in one trip, e.g. railway station, train, railway station is assessed as one “journey”Minimum 6-7, potentially 33+Minimise visits.

LowerSmall cafes (around 25 seats), small shops, infrequently used buildings e.g. churches (outside of services), buildings which, at the time of visit, have very few people inside themUsed by small numbers of people, who are not taking precautions.  Can be poorly ventilated.You are statistically unlikely to encounter an infected person on a single visit, although this risk cannot be excluded. After 3 to 6 visits, statistically you are likely to encounter one infected person over all of those visits. Remember, however, especially with rising infection levels, you may well be unlucky and meet a Covid-infected person on your first visit.  Minimise visits. Maximise fresh air ventilation (open windows if possible, etc).   The Covid risk is rising. While statistically the risk remains lower, we encourage a cautious approach to taking risks. Not wearing a PPE respiratory mask (FFP2/3 rated) should be exceptional when the risk is clearly lower, for example in a nearly empty building.
LowOutdoors (except when in a dense crowd)The moving fresh air makes transmission of Covid from one person to another unlikely, except where two people are very close together.The number of infected people is less relevant because the risk of transmission of Covid from one person to another is unlikely.Avoid very close contact (under 1m) with potentially infected people. For complete peace of mind, remain 2m from potentially infected people.
Covid, flu, norovirus, bird flu and measles are all airborne. An infected person in an unventilated indoor place creates an invisible cloud of virus which hangs in the air like smoke for you to breathe in. The virus cloud can be dispersed and made less harmful, or harmless, using fresh air ventilation – e.g. opening a window or door. Fresh air is the enemy of Covid and the friend of Covid-cautious people. Another way to deal with an indoor cloud of Covid is to use a HEPA filter. These filters suck in the air, remove the viruses, and blow out virus-free clean air. HEPA filters are essential when an indoor space cannot be ventilated with fresh air, e.g. no (or little) opening windows. PPE respiratory masks filter viruses out of the air you personally breathe, if they are fitted and used correctly. PPE masks are the last line of defence against airborne viruses. As we explain in the table above, Covid-cautious people can use one or a combination of these precautions to help make indoor spaces safer for them.

Covid is not just dangerous for clinically-vulnerable people. The virus has been proven to have an adverse health impact on most people who catch Covid. No-one should be relaxed about catching Covid.
