    Latest official data suggest COVID-19 activity in England is rising again. Cases, test positivity, hospital occupancy and deaths all increased from recent lows, although levels remain well below largest pandemic waves. For many, infection may be mild, but increasing transmission can have serious consequences for older adults, clinically vulnerable people, &amp;amp; those at risk of Long COVID. Reducing spread through good ventilation, cleaner indoor air &amp;amp; staying home when unwell helps p...

    Infection prevention is about far more than spotting dust or checking cleaning checklists. This article by Tommy Davis argues for structured, multidisciplinary infection prevention rounds that examine clinical workflows, waste handling, device care, hand hygiene and environmental hygiene together, while recognising EVS staff as essential patient-safety partners. Valuable reminder that preventing healthcare-associated infections requires shared accountability... https://www.infectioncontroltoday...

    The HSJ argues the NHS needs a summer plan as much as a winter one — and it aligns with serious concerns about heat, air quality and climate pressures already shaping demand. Environmental stressors aren’t seasonal. They’re structural. Link: https://www.hsj.co.uk/service-redesign/the-nhs-needs-a-summer-plan-as-well-as-a-winter-one/8123920.article

    Independently produced COVID‑19 chart showing that infections, hospital activity and deaths continue at a steady, persistent level. The visuals highlight ongoing circulation rather than elimination. It&amp;#39;s clear that airborne viruses spread most easily indoors, and that clean indoor air, ventilation and filtration remain essential protections. Long COVID research must stay central, and science, data and public education are key to keeping people safer. Data source: @ukhsa.bsky.social.

    England’s latest COVID data show continued circulation despite fewer published metrics. This independent chart tracks cases, hospital activity, deaths and positivity, while the absence of Long COVID data remains noticeable — and is a reminder of why better ventilation and stronger IPC still matter.

    SARS, SARS‑CoV‑2 and other sarbecoviruses keep showing how disruptive this viral group can be. Their continued evolution underlines why vaccines aiming for broad, cross‑sarbecovirus protection matter so much for future preparedness.

    This RIDDOR consultation to revise disease reporting appears to make no mention of COVID‑19, airborne transmission, or Long COVID? That silence matters.

    SARSCoV2 is now in Hazard Group within UK lab rules. A regulatory change for labs, the biology hasn’t changed. That’s paperwork, not a sign that the virus is harmless.

    A logarithmic line chart titled “Tracking COVID‑19 Data in England: independently produced chart using official data (Feb 2020 to 13 May 2026)”. The x‑axis runs from early 2020 to May 2026, with vertical markers every four weeks. The y‑axis is logarithmic, ranging from 1 to 1,000,000. Four datasets are plotted as dotted lines: • Blue: positive COVID‑19 cases • Magenta: COVID‑19 patients in hospital • Red: deaths involving COVID‑19 • Purple: PCR test positivity (%)

    England’s COVID data from 2020–26 show the virus is still circulating — still causing infections, hospitalisations, and still taking lives. Chart uses official data (UKHSA, NHS England, ONS). What’s changed isn’t the potential impact, but the lack of any real attention. Not forgetting Long COVID. Curves rise and fall through successive waves, then settle into lower but persistent levels. Despite reduced testing and attention, all measures remain above zero, showing ongoing transmission &amp;amp;...
