COVID nails: these changes to your fingernails may show you’ve had coronavirus

Discoloured or misshapen fingernails have been reported by some patients following a COVID-19 infection.

The main signs of COVID-19 are fever, a cough, fatigue and a loss of your sense of taste and smell. Signs of COVID-19 in the skin have been noted too. But there’s another part of the body where the virus appears to have an impact: the fingernails.

Following a COVID-19 infection, for a small number of patients the fingernails appear discoloured or misshapen a number of weeks later – a phenomenon that’s been dubbed “COVID nails”.

One symptom is a red half-moon pattern that forms a convex band over the white area at the base of fingernails. This seems to present earlier than other COVID-related nail complaints, with patients noticing it less than two weeks after being diagnosed. Multiple cases have been reported – but not many.

Red half-moon nail patterns like this are generally rare, and previously haven’t been seen so close to the nail base. So having this pattern appear like this could exclusively be an indication of a COVID-19 infection.

The mechanism underlying this half-moon patterning remains unclear. A possible cause could be blood vessel damage associated with the virus itself. Alternatively, it may be due to the immune response mounted against the virus causing mini blood clots and discolouration. Importantly, these marks don’t appear to be anything to worry about, as patients are otherwise asymptomatic – although it is unclear how long they stay for, having lasted from between one week to over four weeks in the cases reported.

Signs of physical stress

A few patients have also found new horizontal indentations in the bases of the nails of their fingers and toes, which are known as Beau’s lines. These tend to appear four weeks or more after a COVID-19 infection.

Beau’s lines occur when there is a temporary interruption in nail growth due to a physical stress on the body, such as an infection, malnutrition or side-effects of medications such as chemotherapy drugs. While it’s plausible that they’re caused by COVID-19, they’re definitely not an exclusive symptom of the disease.

As nails grow between 2mm and 5mm a month on average, Beau’s lines tend to become noticeable four to five weeks after the physical stress happens – as the nail grows, the indentation is revealed. The timing of the stressful event can be therefore estimated by looking at how far the Beau’s lines are from the nail base. There’s no specific treatment for Beau’s lines, as they tend to eventually grow out if the underlying condition has resolved.

Currently, the available evidence suggests that there’s no association between the severity of COVID-19 infection and the type or extent of nail changes.

Other unusual findings

The above are the two more common COVID-related nail complaints, but researchers have recorded some other unusual occurrences as well.

One female patient’s nails loosened from the nail base and eventually fell out, three months after her infection. This phenomenon is known as onychomadesis and is thought to happen for similar reasons to Beau’s lines appearing. This patient didn’t receive treatment for these changes as new healthy nails could be seen growing underneath those that detached, indicating that the issue was beginning to resolve itself.

Another patient, 112 days after testing positive, witnessed orange discoloration to their nail tips. No treatment was given and the discoloration had still not resolved after a month. The underlying mechanism behind this is unknown.

And in a third case, a patient had horizontal white lines appear on their nails that don’t disappear with pressure. These are known as Mees’ lines or transverse leukonychia. They appeared 45 days after testing positive for COVID-19. These tend to resolve with nail growth and do not require treatment. Mees’ lines are thought to be caused by the abnormal production of proteins in the nail bed due to systemic disorders.

A mystery – for now

Although these three conditions all followed a COVID-19 infection, because we only have limited patients to look at in each case, it isn’t possible to say yet whether they were caused by the disease. It is entirely possible that all three are unrelated to the condition.

Indeed, even with the Beau’s lines and red half-moon pattern, there is still a long path to confirm a definite link between these changes and COVID-19 as well as the mechanisms behind them. For all these conditions, we’ll need many more cases to be reported before we can say with certainty that there’s a link.

Plus, even if there is a causative link, it’s important to remember that not all patients with COVID-19 will have these nail conditions. And some of these abnormalities may not necessarily mean someone has had COVID-19. At best, we should regard these as potential indicators of a past infection – and not definitive proof.

COVID-19 may never go away, but practical herd immunity is within reach

It is unlikely that we will reach full herd immunity for COVID-19. However, we are likely to reach a practical kind of herd immunity through vaccination.

The level of immunity needed — either through vaccination or infection — for practical herd immunity is uncertain, but may be quite high. (Shutterstock)

When people say that we won’t reach “herd immunity” to COVID-19, they are usually referring to an ideal of “full” population immunity: when so many people are immune that, most of the time, there is no community transmission.

With full herd immunity, most people will never be exposed to the virus. Even those who are not vaccinated are protected, because an introduction is so unlikely to reach them: it will sputter out, because so many others are immune — as is the case now with diseases like polio and mumps.

The fraction of the population that needs to be immune in order for the population to have “full” herd immunity depends on the transmissibility of the virus in the population, and on the control measures in place.

It is unlikely we’ll reach full herd immunity for COVID-19.

For one thing, it appears that immunity to COVID-19 acquired either by vaccination or infection wanes over time. In addition, SARS-CoV-2 will continue to evolve. Over time, variants that can infect people with immunity (even if this only results in mild disease) will have a selective advantage, just as until now selection has mainly favoured variants with higher transmission potential.

Also, our population is a composition of different communities, workplaces and environments. In some of these, transmission risk might be high enough and/or immunity low enough to allow larger outbreaks to occur, even if overall in the population we have high vaccination and low transmission.

Finally, SARS-CoV-2 can infect other animals. This means that other animal populations may act as a “reservoir,” allowing the virus to be reintroduced to the human population.

Practical herd immunity

Nonetheless, we are likely to reach a practical kind of herd immunity through vaccination. In practical herd immunity, we can reopen to near-normal levels of activity without needing widespread distancing or lockdowns. This would be a profound change from the situation we have been in for the past 18 months.

Practical herd immunity does not mean that we never see any COVID-19. It will likely be with us, just at low enough levels that we will not need to have widespread distancing measures in place to protect the health-care system.

What level of immunity (either through vaccination or infection) we need for practical herd immunity is uncertain, but it may be quite high. The original strain of SARS-CoV-2 was highly transmissible and transmission is thought to be higher still for some variants of concern.

The amount of immunity we need will also depend on what level of controls we are willing to maintain indefinitely. Continued masking, contact tracing, symptomatic and asymptomatic testing and outbreak control measures will mean we will require less immunity than we would without these in place.

Some estimates suggest that we may need two thirds of the population to be protected either by successful vaccination or natural infection. If 90 per cent of the population is eligible for vaccination, and vaccines are 85 per cent effective against infection, we can obtain this two thirds with about 90 per cent of the eligible population being vaccinated or infected naturally.

The United Kingdom has already exceeded these rates in some age groups. Higher rates are even better, because there is still uncertainty about the level of transmissibility and vaccine efficacy against infection (although research shows they are very good against severe disease). We don’t want to discover that we do not have enough immunity through vaccination and have another serious wave of infection.

Emerging variants

Higher vaccine uptake will mean there are fewer infections before we reach practical herd immunity. The remaining unvaccinated individuals will be safer, protected indirectly by the immunity of those around them. Outbreaks will be smaller and rarer, and there will be fewer opportunities for vaccine escape variants to arise and spread.

That said, variants of SARS-CoV-2 will continue to emerge, and selection will favour variants that escape our immunity. Vaccine developers will continue to broaden the spectrum of the vaccines that are available, and boosters will hopefully allow us to maintain long-term practical herd immunity.

It’s possible that an immune escape variant will emerge that is severe enough, and transmissible enough, that it will cause a new pandemic for which we do not have even practical herd immunity. But barring that, while we may not be free of COVID-19, we can be confident that in the not-too-distant future it will be manageable when we return to near-normal life.

UK Government Adviser Says Mask Mandates Should Continue "Forever"

Authored by Paul Joseph Watson via Summit News,

A UK government adviser and former Communist Party member Susan Michie says that mask mandates and social distancing should continue “forever” and that people should adopt such behaviour just as they did with wearing seatbelts.

Michie, who is a Professor of Health Psychology at UCL and a leading member of SAGE, said such control measures should become part of people’s “normal” routine behaviour.

"Vaccines are a really important part of pandemic control but it is only one part. [A] test, trace and isolate system, [as well as] border controls, are really essential. And the third thing is people’s behaviour. That is, the behaviour of social distancing, of… making sure there’s good ventilation [when you’re indoors], or if there’s not, wearing face masks, and [keeping up] hand and surface hygiene."

"We will need to keep these going in the long term, and that will be good not only for Covid but also to reduce other [diseases] at a time when the NHS is [struggling]… I think forever, to some extent…"

"I think there’s lots of different behaviours that we have changed in our lives. We now routinely wear seatbelts – we didn’t use to. We now routinely pick up dog poo in the parks – we didn’t use to. When people see that there is a threat and there is something they can do to reduce that [to protect] themselves, their loved ones and their communities, what we have seen over this last year is that people do that."

Michie’s comments once again emphasize how many scientific advisers have become drunk on COVID-19 power and never want to relinquish it.

“Unsurprisingly, Channel 5 News made absolutely no effort to scrutinise these claims. The programme’s presenter raised no objection to the idea that mask-wearing and social distancing could continue “forever”, resorting only to friendly laughter,” writes Michael Curzon.

“Professor Michie’s co-panellist, a fellow scientist at UCL, Dr Shikta Das, said:

“I think Susan has made a very good point here,” adding that the vaccine roll-out has created a “false sense of security”.

She concluded:

“I don’t think we are yet ready to unlock.”

How’s all that for balance!

Perhaps unsurprisingly, Michie is known to be a long-time Communist hardliner and was so zealous in her beliefs she garnered the nickname “Stalin’s nanny.”

Her sentiment echoes that of fellow government adviser Professor Neil Ferguson, who once acknowledged that he was surprised authorities were able to “get away with” the same draconian measures that Communist China imposed at the start of the pandemic.

“[China] is a communist one-party state, we said. We couldn’t get away with [lockdown] in Europe, we thought… and then Italy did it. And we realised we could,” said Ferguson.

Venezuela Says US Sanctions Blocking COVID Vaccines: 'Global Health System' As Geopolitical Weapon

Authored by Brett Wilkins via via CommonDreams.org,

Venezuelan Vice President Delcy Rodríguez has accused the US-backed international financial system of blocking the country's access to Covid-19 vaccines under the COVAX program, even though Venezuela has paid all but $10 million of the $120 million it owes.

Appearing in a televised address, Rodríguez said Venezuela was unable to pay the remaining $10 million because it was being blocked from transferring funds to the Switzerland-based GAVI Vaccine Alliance, which directs COVAX. "The financial system that also hides behind the U.S. lobby has the power to block resources that can be used to immunize the population of Venezuela," she said.

Venezuelan Foreign Minister Jorge Arreaza tweeted a letter from COVAX stating that it "received notification from UBS Bank" that four payments, totaling just over $4.6 million, were "blocked and under investigation."

Arreaza said that "Venezuela has paid all of its commitments," adding that "the bank has arbitrarily blocked" the country's final payments and calling the situation "a crime."

The vice president and foreign minister's remarks follow accusations from Venezuelan President Nicolás Maduro last week that "organizations of US imperialism" are engaged in an effort to stop vaccine producers from selling doses to the country.

"Venezuela might be the only country in the world that is subject to a persecution against its right to freely purchase vaccines," said Maduro, according to Venezuelanalysis. "Venezuela is besieged so that it cannot buy vaccines."

Successive US administrations have targeted Venezuela with economic sanctions that critics say have devastated the nation's once-thriving economy and have caused tremendous suffering for the poor and working-class people whose dramatic uplift was once hailed as the great success of the Bolivarian Revolution launched under the late President Hugo Chávez. 

According to a 2019 report from the Center for Economic and Policy Research, a progressive think tank based in Washington, D.C., as many as 40,000 Venezuelans have died due to sanctions, which have made it much more difficult for millions of people to obtain food, medicine, and other necessities. 

Maduro also denounced the World Health Organization (WHO) for its role in delaying vaccine delivery to Venezuela. The president had expected "many millions" of the Covid-19 jabs to be delivered in July and August. "The COVAX system owes a debt to Venezuela," asserted Maduro. "We made a deposit in April and we are waiting for the vaccines."

That $64 million deposit to GAVI came after a rare deal between the Maduro administration and Juan Guaidó, the coup leader recognized by the United States and dozens of other nations as Venezuela's legitimate head of state despite never having been elected.

Adept at circumventing US interference in its affairs, Venezuela turned to China, Russia, and Cuba to launch its mass vaccination program, which aims to inoculate 70% of the population this year. Earlier this month, the country reached a deal to buy and locally manufacture the Russian EpiVacCorona vaccine. Venezuela has also already acquired about three million doses of the Russian Sputnik V and Chinese Sinopharm jabs, and last month began clinical trials on Cuba's Adbala vaccine.

Compared to other nations in the region, Venezuela has reported a very low rate of coronavirus infections and deaths. According to Johns Hopkins University's Coronavirus Resource Center, there have been nearly 248,000 reported cases and 2,781 deaths in the country of 28.5 million people during the ongoing pandemic. Neighboring Colombia, with just over 50 million people, has reported more than 3.6 million cases and over 94,000 deaths.
