Antibiotics may raise colon cancer risk, massive study suggests

  Antibiotics may raise colon cancer risk, massive study suggests This is the largest epidemiological study to assess this potential risk.Past studies hinted that antibiotics can cause lasting changes to the gut microbiome — the community of microbes that live in the digestive tract — and that these changes may be linked to a heightened risk of colon cancer. Now, in the largest epidemiological study to ever explore this link, researchers report that the heightened risk may be specific to cancers in the so-called proximal colon, the part of the colon that connects to the small intestine and starts in the lower-right abdomen.

Mistakes at a disgraced Covid testing laboratory that incorrectly told up to 43,000 people they were not infected with the virus began a week earlier than feared, it was revealed today.

The Immensa Health Clinic in Wolverhampton was given nearly £170million to analyse PCR swabs.

But last week health chiefs revealed 'technical issues' at the clinic, where workers have been filmed playing football and wrestling on shift, saw tens of thousands of tests wrongly processed.

The UK Health Security Agency, which took over from the now-defunct PHE, at the time said patients were given false negatives in the five weeks between September 8 and October 12.

Random COVID-19 testing in school district increased case detection 6x

  Random COVID-19 testing in school district increased case detection 6x Researchers from the University of Nebraska Medical Center found that regularly testing students at school could increase the rate of COVID-19 case detection six-fold.Researchers from the University of Nebraska Medical Center instituted a five week-pilot testing program in three schools in the local Omaha area.

But the agency last night announced the problems at the lab started six days earlier than feared, on September 2.

A spokesperson for UKHSA told MailOnline the correct duration of the lab mishaps were discovered as part of its ongoing investigation.

But it insisted the finding does not impact the number of coronavirus swab samples which were incorrectly processed. All affected people have been contacted, health bosses claimed.

Cases in the South West have already reached a record high and more than doubled in a week after the error was spotted.

There are concerns that the testing error has come at the worst possible time, with daily cases approaching peak-second-wave levels and the UK's booster programme struggling to get off the mark as the country heads towards a harsh winter.

World Health Organisation will start NEW Covid investigation

  World Health Organisation will start NEW Covid investigation Experts will look into whether Covid leaked from a lab in Wuhan, at the end of 2019 - a claim denied by China, which also wants the WHO to examine if the virus originated in another country. It comes after US President Joe Biden ordered intelligence agencies to investigate the 'lab leak' theory.A WHO spokesman said the new team's 'priority needs to be data and access in the country where the first reports were identified'. The earlier investigation recommended China examine the earliest suspected coronavirus cases, with the team claiming in its final report that the data provided by the country was insufficient.

NHS Test and Trace last week suspended testing operations at Immensa's lab and an investigation is being carried out to work out why it took a month to spot the testing error.

There are no technical issues with test kits themselves and people should continue to test as normal, the UK Health Security Agency (HSA) said.

Dr Jenny Harries, head of the HSA, said last week it was unclear what had caused the blunder.

Test and Trace has contacted everyone who could still be infectious to advise them to take another test, while close contacts who are symptomatic are also advised to take a test.

Covid-19: Nurseries demanding ‘invasive’ PCR tests on toddlers ‘should be challenged in court’

  Covid-19: Nurseries demanding ‘invasive’ PCR tests on toddlers ‘should be challenged in court’ Professor Allyson Pollock said it is "madness" that children under-5 face being sent home to endure repeated swab tests every time they have a cough or fever.Allyson Pollock, clinical professor of public health at Newcastle University, said it is “madness” that children who develop one of the two “classic” coronavirus symptoms are not allowed to return to the setting until they have a negative swab test – and that the issue should be challenged in court.

Almost one in 50 people had Covid in England last week

England's Covid cases have reached their highest level since mid-January with nearly one in 50 infected with the virus last week, official data has shown amid growing fears that the impending fourth wave.

Office for National Statistics (ONS) figures show around 977,900 were infected in England on any given day in the week up to October 16.

Cases rose 9.88 per cent on last week's figure of 890,000 — the fourth week in a row infections have increased.

When modelling the level of Covid infections among different age ranges in England, the ONS said rates have increased in all age groups except for those aged 25 to 34, where the trend was uncertain.

What should you do if you get a positive lateral flow test followed by a negative PCR? Covid rules explained

  What should you do if you get a positive lateral flow test followed by a negative PCR? Covid rules explained A regional public health official has said people should continue to isolate even if they receive a negative PCR result if they are experiencing symptoms . Becky Reynolds, director of public health for Bath and North East Somerset council, told the BBC: “The advice is also to think about your local situation, do an individual risk assessment – so what is the likelihood that even though the PCR is negative, that you may still have Covid? “If thinking it through there is quite a chance you have Covid, even if the PCR is coming back negative, then regard it as Covid and self-isolate.

The percentage of people testing positive remains highest for those in school years seven to 11, at 7.8 per cent, up week-on-week from 7.1 per cent.

Cases are estimated to have increased in all regions of England except south-east England and the West Midlands, where it appeared to level off, and north-east England and Yorkshire and the Humber, where the trend was uncertain.

New Covid variant fears erupt over mysterious test results - urgent investigation launched

  New Covid variant fears erupt over mysterious test results - urgent investigation launched A NEW Covid variant could be the cause of strange PCR and lateral flow tests (LFT) results, sparking fears across the country.According to the i, the UK Health Security Agency (UKHSA) has refused to speculate whether a new variant could be the cause of the strange findings.

In northwest England and southwest England, around one in 45 people was likely to test positive in the week to October 16. This was the highest proportion for any region.

London and south-east England had the lowest proportion, at around one in 75.

Professor Jim Naismith, director of the Rosalind Franklin Institute at the University of Oxford, said: 'Today’s ONS figures for week ending October 16 are not good news.

'These data are the most valuable resource we have for judging the virus. The day to day results are a poor indicator.

'The power of the vaccines can be seen in the much lower death and hospitalisation rate that this high level of infections is currently causing.

'There is evidence of slight waning of immunity. Vaccines are extremely effective at preventing deaths and hospitalisation; they are less good at preventing infection.

He continued: 'Even extremely effective is not perfect. A slight decrease in immunity still means you are protected against the worst of the disease but might lead to an increase in cases.

'For those offered a booster (third) jab, science shows it is incredibly effective. I would advise taking it immediately it is offered. For those who have not had their first jab, they are almost certain to contract Covid if they have not already done so.'

Lateral flow tests 'detect people at greater risk of spreading Covid'

  Lateral flow tests 'detect people at greater risk of spreading Covid' British and American researchers found rapid tests are 90 per cent effective at detecting the virus in people who are at their most infectious. And the swabs are 80 per cent effective overall.British and US researchers found rapid tests are 90 per cent effective at detecting the virus in people who are at their most infectious.

The UKHSA said the problems at the lab was an 'isolated incident' and the number of tests processed by the lab is 'small in the context of the wider network and testing availability is unaffected around the country'.

Cases have surged in the South West since the errors took place.

A total of 35,629 new coronavirus cases were recorded in the region in the seven days to October 16 — the equivalent of 629.6 per 100,000 people. This is up from 17,593 cases, or 310.9 in the previous seven days.

And estimates from the Office for National Statistics (ONS) today showed 2.2 per cent of people in the region were thought to have the virus on any given day in the seven days up to October 16, the highest infection levels in the country.

Professor Paul Hunter, an epidemiologist at the University of East Anglia, told MailOnline he believed the faulty test results were 'having an impact' on case rates and estimated the error led to thousands of avoidable infections.

He estimated that up to 8,000 people will have caught the disease from a person given the wrong result, based on rough estimates about the number of people who isolate when they're unwell, regardless of PCR result.

But he said: 'It could be more, there are still several key unknowns here.'

'Clearly any substantial number of preventable false negatives means that people who would otherwise have been self-isolating are no longer doing so,' Professor Hunter said.

The problems in the lab led to 'enough preventable infections to be a worry but probably not a enough to make a big difference in the epidemic', he added.

UK's daily Covid cases fall again... by a FIFTH

  UK's daily Covid cases fall again... by a FIFTH It comes as the UK's largest official surveillance study found that cases levelled off last week for the first time in nearly three months - but prevalence is still high.The Department of Health's usual update showed there were 34,029 new infections in the past 24 hours, marking a 22 per cent fall on last Friday.

It comes as ONS data today showed England's Covid cases reached their highest level since mid-January with nearly one in 50 infected with the virus last week.

Around 977,900 people were infected in England on any given day in the week up to October 16.

Infections have not been as high since the country began to recover from the darkest days of the second wave in at the start of the year.

Cases rose 9.88 per cent on last week's figure of 890,000 — the fourth week in a row infections have increased.

Meanwhile, separate data from the UKHSA today showed the the R rate rose on last week and is around 1.0 to 1.2, up from 0.9 to 1.1. It is the first time R has definitely been above one since August.

Figures from the Department of Health — based on the Government's official testing programme as opposed to the random swabbing of thousands of Brits — showed cases across the UK breached 50,000 for the first time in three months yesterday.

Medics warn cases will continue to spike unless Britain doubles the speed of its vaccine booster rollout. Only 4million out of the 8.7million patients in England who are eligible for a booster now have had one, including just a third of care home residents and half of over-80s.

It is being held up by the NHS sending texts to elderly Britons who 'do not know how to use their phones', doctors warned today.

Boris Johnson yesterday issued a desperate plea for more Britons to come forward for their boosters to 'fortify' people's defences against the virus, amid fears the rising cases could lead to last-minute curbs ahead of Christmas once again.

The Government has so far resisted growing pressure to revert to its winter 'Plan B' to bring back masks and WFH guidance despite surging case numbers and in the face of doctors accusing them of being 'wilfully negligent'.
