These are the stories of the British coronavirus that you need to know today.
Immune weakness
The latest data from the Imperial REACT-2 study of 365,104 people who underwent finger stab testing at home show that coronavirus immunity declines over time.
so Preprint, Researchers found that between June 20th and September 28th, the number of people tested positive for antibodies decreased from nearly 6% to 4.4%.
The downward trend was seen in all regions of the country and in all age groups. However, it is not seen in healthcare professionals, and the authors suggest that it may indicate repeated or higher initial exposure to the virus.
Research leader Professor Paul Elliott commented: “Our study shows that the proportion of antibody-positive people decreases over time. An antibody-positive test does not mean that COVID-19 is immune. The level of immunity is unknown. Antibodies, or provide a duration of this immunity. Even if someone tests positive for the antibody, take a social distance measurement, a cotton swab test if there are symptoms, You must follow national guidelines, such as wearing a face cover if necessary. “
Eleanor Riley, a professor of immunology and infectious diseases at the University of Edinburgh, commented through the Science Media Center, saying: Other aspects of immunity, such as antibody concentration, antibody function, or T cell immunity, do not examine the trajectory of antibody levels in the same individual over time. Nonetheless, the data emphasize concerns that antibodies induced by natural infections may be possible. Short-lived (as in other seasonal coronaviruses). “
Oxford coronavirus vaccines, on the other hand, have been shown to provoke an immune response in both young adults and the elderly.
A spokeswoman for the manufacturer AstraZeneca said, “Immunogenic reactions were similar between older and younger people and were less reactive in older people with a higher severity of COVID-19 disease. It is encouraging to confirm. “
Latest data
Today’s Daily data An additional 22,885 UK positive tests were reported, killing 367 people. Mortality is often low on weekends and can increase at the beginning of the week.
The hospital has 9199 COVID-19 patients and 852 ventilator beds are used.

Dr. Yvonne Doyle, Medical Director of UK Public Health Services, commented: “The mortality trend continues to increase and may continue for some time. Every day, more people are positive and hospitalizations are increasing.”
National Bureau of Statistics Weekly (ONS) data ending October 16 show that the number of registered deaths in England and Wales was 6.8% above the five-year average.
“New coronavirus (COVID-19)” increased by 6.4% from 4.4% in the previous week.
Deaths in hospitals remained below the five-year average, while deaths in private homes and long-term care facilities were above the five-year average.
The death toll from COVID-19 in the UK has passed another landmark to 61,116. Parents report. This number comes from the latest daily statistics in addition to the latest weekly statistics from ONS, Scotland and Wales.
Divide Our data Only about one-third of people who tested positive for COVID-19 showed evidence of symptoms at the time of testing.
University of Exeter research published Emergency medicine Hospital mortality for severe COVID-19 patients was found to have declined since the peak of the pandemic.
In late March, COVID-19 mortality was 26% in patients admitted to highly dependent units and 41% in the intensive care unit. Mortality in June was 7% for highly dependent unit admissions and 21% for intensive care unit admissions.
On Thursday, Nottingham will be the newest region of England and will move to the highest Tier 3 limits. A statement on the city council’s website said, “As the number of cases of the virus increases in the city and the number of people hospitalized increases, stricter rules are needed. COVID- in all areas of the city and in all. 19 cases are seen. Age group. “
blood pressure
UK and UK and international studies show that people with high blood pressure are unlikely to have increased cell invasion of the COVID-19 virus even if they take ACE inhibitors to treat it. That is. European Heart Journal.
There was concern about how the SARS-CoV-2 virus could use the ACE2 protein to infect the body.
Professor Brian Williams of the University College London commented: “There are many speculations about whether hypertension and the drugs we commonly use to treat it increase the risk associated with COVID-19 infection in millions of people treated for hypertension. This new study refutes previous speculation that the drugs we commonly use to treat hypertension lead to an increase in the number of COVID-19 receptors on the surface of the lungs. This is a very important discovery. “
Cognitive impairment
A Preprint From Imperial College London, we found that many people who recovered from COVID-19 “showed serious cognitive impairment.”
The study, which has not yet been peer-reviewed, was conducted by analyzing cognitive test data from 84,285 Great British Intelligence test participants who self-reported COVID-19 infection.
The authors write: “It was quite effective not only in hospitalized individuals, but also in mild, biologically confirmed cases that did not report dyspnea. A more detailed analysis of performance shows that COVID-19 affects multisystems. Supports the hypothesis of giving. About human perception. “
Dr. David Strain, a senior clinical lecturer at the University of Exeter, commented: “Only a small number of people tested positive for COVID. Therefore, there is uncertainty about the reliability of information about severity. Symptoms.”
He added: “It is not clear if cognitive deficits are permanent. Many COVID symptoms can last months after the serious part of the illness is over, and cognitive deficits can eventually recover. There is no comparison with people suffering from other respiratory illnesses such as influenza – Is this long-term effect on cognition different from influenza? “
Fireworks concerns
Plastics and reconstruction surgeons are urging people not to launch their own fireworks, as many organized fireworks festivals have been canceled due to COVID-19 restrictions.
A pollster from the British Association of Plastics, Reconstruction and Aesthetic Surgeons found that 37% of people held a bonfire event at home this year, fearing it could reverse the decline in A & E attendance due to fireworks injuries. I was thinking of doing it.
Mark Henry, President of BAPRAS, said in a statement: Due to the untreated portion of the surgery, we cannot afford to increase preventable injuries and encourage people to rethink before buying personal fireworks. “
