The vaccine sceptic and anti-lockdown campaigner Laurence Fox has said he has coronavirus.

The actor, who finished sixth in last years London mayoral elections, tweeted a picture on Sunday of a positive lateral flow test.

Above it, he wrote: In other news, felt shivery and crap yesterday. Turns out I have been visited by Lord Covid at last and have the Omnicold (if the LFT is to be believed!) On the #Ivermectin, saline nasal rinse, quercetin, paracetamol and ibruprofen. More man flu than Wu-flu at the moment.

Ivermectin is an anti-parasitic treatment used mainly on animals but which is approved in different doses to treat some parasitic worms in humans. It has not been proved to be effective at preventing or treating Covid, but has been promoted by vaccine-sceptic public figures such as the comedian and podcast host Joe Rogan, who said he used the drug to treat himself when he became sick with Covid, and the Fox News host Tucker Carlson.

Foxs tweet came four days after he posted a picture of himself wearing a T-shirt with a slogan saying, No vaccine needed, I have an immune system. In another tweet posted on Sunday, he said he was on day two of the virus.

After a number of people commented in response to Foxs tweet asking where he had got the ivermectin and why he was taking it, he responded by saying: Not only do you only have to sign a form saying you feel well to get into Mexico, but you can also buy drugs like Ivermectin over the counter that the vaccinaholics dont want you to get hold of here. Im so happy to be joining the natural immunity club. Going to have a nap.

Launching his mayoral campaign last year, Fox said he would not get the Covid jab until after 2023, by which time he claimed all the tests needed to convince him of its safety would be completed.

He has also cast doubt on the UKs death toll from the pandemic, claiming that some doctors were seeking to add non-Covid deaths including that of his mother in 2020 to the official tally to support the governments fear-based narrative.

And Fox has questioned the scientific basis of long Covid, which the Office for National Statistics estimates is affecting 1.3 million people, or 2% of the population, in the UK, based on people self-reporting symptoms that last more than a month after a Covid infection.

Laurence Fox says he has coronavirus and is taking ivermectin - The Guardian

The omicron variant of Covid-19 was discovered less than three months ago, but it rocketed case numbers to record highs. Yet almost as rapidly as they rose, new infections plummeted in countries like the United Kingdom, South Africa, and now the United States.

Omicron caused some of the pandemics tallest, sharpest spikes in Covid-19 infections as it overtook previous variants like delta, but several waves triggered by earlier variants followed a remarkably similar pattern. Almost as steeply as cases rose, they fell.

Why did this happen? Why didnt omicron cases rise and fall slowly or level out at a high or moderate level?

I think you may get different answers from different experts, said Eleanor Murray, an epidemiologist at Boston University, in an email. This isnt just a curiosity: Researchers are trying to tease out the reasons in the hope of flattening peaks in the future.

Understanding why cases are rising and falling is crucial for figuring out what kinds of public health strategies are working. Its also important for anticipating what comes next and how to deploy resources like medical workers, hospital beds, vaccines, and treatments.

The Covid-19 spikes were seeing are not just an intrinsic fact of nature. Theyre partly a consequence of how we respond or dont to changes in the virus and in our society. And as steep spikes are eventually replaced by shallower slopes, they will also reveal when the acute Covid-19 pandemic has ebbed and given way to an endemic disease.

The omicron variant of SARS-CoV-2, the virus that causes Covid-19, appeared at just the right time to cause a huge infection spike. It took root in the Northern Hemisphere as holiday travel picked up and cooler temperatures pushed people indoors, helping it travel long distances and spread locally through person-to-person contact.

Omicron also had the right mix of traits to catch fire. The omicron variant contains mutations that allow it to better evade immune protection while spreading faster than any prior known variant. Even people vaccinated against Covid-19 began getting infected in large numbers as protection from their initial doses started to waver, though most experienced mild symptoms. All these factors together led to lots of infections happening very quickly.

It has infected everybody that could be infected out and about and that means automatically it will run out of people to infect and start coming down as fast as it went up, said Ali Mokdad, an epidemiologist at the Institute for Health Metrics and Evaluation at the University of Washington.

While omicron has been the most extreme example of this phenomenon, earlier variants also caused sharp spikes and declines. South Africa, for instance, saw distinct peaks associated with different variants. Most of these peculiar stalagmites in South Africa were symmetrical except for the delta wave last summer, which saw a brief resurgence on its way down.

[T]he shape of a spike then decline is what we generally expect in a single population, said Justin Lessler, a professor of epidemiology at the University of North Carolina School of Public Health, in an email.

A key variable is the basic reproductive number of the virus, or R0, which is the average number of people that one infected individual tends to infect. If that number is above one, the epidemic grows exponentially; if it is below one, it declines exponentially, Lessler said.

As more people get infected with a coronavirus variant, there are fewer people left to infect. When the basic reproductive number falls below one, new infections reach their peak and then decline. To plateau, the rate of new infections has to stabilize somewhere near one, but that would require an unusual set of conditions, according to Lessler.

The idea that disease outbreaks are generally symmetrical is an old one. William Farr observed in the 1840s that smallpox epidemics followed a mathematical pattern, though his formula, known as Farrs law, resulted in a bell-shaped curve. But diseases rarely follow such neat curves.

That has been generally discredited as a law since it doesnt allow for things like changes in susceptibility due to different levels of immunity/immune waning, movement in and out of populations, and changes to risk and exposure behaviors, said Murray.

Thats been evident during the Covid-19 pandemic. Some countries like South Korea saw more gentle hills as different variants took root, while others like Brazil experienced asymmetrical, jagged peaks throughout the pandemic. Some of that is due to delays in identifying and reporting cases. In some places, variants like delta and omicron overlapped. At the country level, case curves can change shape as the pandemic spreads over time from urban to rural areas or can peak at different times depending on the region.

Then one has to account for public health interventions. Vaccines offer significant immune protection (and recovery from Covid-19 can be protective too). Measures like wearing face masks, limiting public gatherings, more rigorous testing, and boosting vaccination efforts also assist in flattening the curve and help waves to crest. People also change their behavior in response to rising infections. In the US, surges in vaccination and testing followed spikes in cases.

That increase in testing and implementation of public health interventions helps us not only reduce transmission, but also more accurately and timely identify dips in cases, said Saskia Popescu, an infectious disease epidemiologist at George Mason University, in an email. These are also good examples of how effective the vaccines have been and our ability to rapidly respond to spikes and novel variants.

So both the shape and the size of an infection spike can be altered with public health tactics. Over time, as immunity builds up in the population, experts expect to stop seeing tall, sharp spikes in Covid-19 cases. The virus probably wont go away entirely, but case counts could form seasonal waves as new variants arise, immunity wanes, and exposure opportunities increase, according to Mokdad.

Covid-19 cases spurred by omicron appear to have peaked already in the US, but the health care system is still facing a stressful time ahead.

When an outbreak peaks in a given community, 50 percent of the infections have occurred and now another 50 will happen as we come down, Mokdad said. So we still have a couple of weeks ahead of us that are dangerous in the United States. ... A small fraction of them are going to the hospitals, but a small fraction of a huge number is a lot.

If public health measures like masking and social distancing are relaxed too soon, cases can bounce back up on their way down. The UK, for instance, reopened schools and relaxed Covid-19 rules before the omicron wave flattened out. Then infections stopped dropping.

The same thing could happen to other countries. That sharp decline will slow down at one point, then it goes back [down] sharply again, Mokdad said. Thats what we are noticing globally.

Even after the omicron wave recedes, the US will still have to contend with people who remain unvaccinated against Covid-19, both inside the country and around the world. And the virus is always changing: Omicron now has a subvariant called BA.2 that is gaining some ground, though its not yet clear what it means for the pandemic overall.

The more the virus spreads, the more likely it is to mutate in dangerous ways. As the current variants have shown, they can quickly spread around the world, regardless of where they originate.

The recurring spikes of Covid-19 cases, fueled in part by variants, should inspire us to redouble our efforts at controlling the disease, especially with vaccines. Were still struggling to avoid these peaks as vigilant infection prevention efforts and global vaccine equity have been a challenge, said Popescu.

A more robust global vaccination effort, coupled with better disease surveillance to catch variants before they spell trouble, could prevent the next wave and finally start to bring the pandemic under control.

OREM, Utah Federal officials worried that more than 174,000 coronavirus patient test results from an Orem lab used by TestUtah were potentially wrong but none of the people who were tested early in the pandemic were told, documents obtained by The Salt Lake Tribune show.

Testing at Timpanogos Regional Hospital may have produced accurateresults.Or its lab may have produced false negatives or false positives, according to documents and interviews with people familiar with the matter.

State health officials knew for months that federal regulators were questioning whether the hospitals lab was following requirements designed to ensure tests are processed accurately, according to interviews and documents. Public officials knew as early as May 2020 about problems at the lab, which did not suspend COVID-19 testing until Aug. 23, 2020.

In the hospitals plan for correcting deficiencies, submitted to regulators the day after it halted its processing of coronavirus tests, it acknowledged:

Once it was determined that verification and validation had not been properly performed, Timpanogos Lab suspended the processing of COVID-19 specimens on the non-validated and non-verified instruments.

The Utah Department of Health sent the following statement to FOX 13 News:

The UDOH was not a party to the CLIA audit. However, our contract with Nomi Health requires that Nomi Health ensure any concerns raised in the audit are resolved. The final audit results from CLIA did not include a requirement or recommendation that any entity notify any patients of potential issues with their test results.

Researchers from Oxford, Sheffield, Cardiff and Manchester have identified abnormalities in the lungs of long COVID patients who are experiencing breathlessness. These abnormalities can't be detected with routine tests, the researchers have said.The study uses hyperpolarized xenon MRI scans to find possible lung damage in long COVID patients who have not been hospitalised with COVID-19 but who continue to experience breathlessness. The research paper is available in medRxiv, pre-print server.The study, known as EXPLAIN, had 36 participants in its pilot stage in three broad groups: the first group is patients diagnosed with long COVID, who have been seen in long COVID clinics and who have normal CT (computerized tomography) scans; the second group is people who have been in hospital with COVID-19 and discharged more than three months previously, who have normal or nearly normal CT scans and who are not experiencing long COVID, and the third group is an age- and gender-matched control group who do not have long COVID symptoms and who have not been hospitalised with COVID-19.

In this study patients are required to lie in the MRI scanner and breathe in a litre of the inert gas xenon. Xenon behaves in a very similar way like oxygen, which helps radiologists to observe how the gas moves from the lungs into the bloodstream.

The result obtained from the pilot study shows significantly impaired gas transfer from the lungs to the bloodstream in long COVID patients.
