How Long Will Covid Last

There’s A Huge Amount Of Studies Showing How Infectious Organisms Can Persist In Tissue And Contribute To Disease Processes Amy Proal

Moldofsky soon identified that those suffering from the condition were sleeping extremely poorly. He suspected this, along with the other symptoms, was a sign of widespread inflammation in the brain, but lacked the funding to investigate further.

But then came a breakthrough. Scientists in China reported discovering fragments of the Sars virus‘ genetic material in various brain cells in patients with post-Sars syndrome. For Moldofsky, this finding explained much of their malaise. “We know there’s a direct connection from our nose to the brain, called the olfactory nerve, and this is probably how the virus got directly into the circulation of the brain,” he says. “I believe these viral fragments were interfering with how their brains were functioning, which would explain the poor sleep quality and other issues.”

“The phenomenon of people developing chronic symptoms after an infectious outbreak is not new,” she says. “If the Sars-CoV-2 virus didn’t do this, it would pretty much be the only documented time where a major pathogen didn’t result in chronic cases. There’s a huge amount of studies, which have been neglected by the mainstream medical community, showing how infectious organisms can persist in tissue, and contribute to disease processes. Some viruses are highly neurotrophic, meaning they can burrow into nerves, and hide out there, and there’s evidence that Sars-CoV-2 is capable of this.”

I Have Been Hearing About Heart Problems In Kids And Young Adults Following The Covid Vaccine Should I Still Get My Child Vaccinated

There has a been a higher-than-expected number of heart inflammation cases after vaccination with the mRNA COVID-19 vaccines, particularly among boys and young men. However, the CDC still strongly recommends that all children 12 years and older be vaccinated.

As of July 12, 2021, 1,047 reports of myocarditis and pericarditis had been reported in people under age 30, particularly in male teens and young adults, after vaccination with the Pfizer/BioNTech or Moderna mRNA vaccines The CDC’s Advisory Committee on Immunization Practices has said available data “suggest likely association of myocarditis with mRNA vaccination in adolescents and young adults.” Even with the increased risk, heart inflammation is a rare occurrence.

Myocarditis and pericarditis after vaccination was most common in males ages 16 to 24. Cases tended to occur within several days after the second mRNA vaccine dose. Most people who developed myocarditis or pericarditis had mild cases and recovered completely after treatment.

If your child develops any of the following symptoms within a week of vaccination, seek medical care:

  • chest pain
  • shortness of breath
  • feeling like your heart is beating fast, fluttering, or pounding.

Why Is The Cdc Asking Fully Vaccinated People To Wear Masks Again Where And When Do I Need To Wear A Mask Now

In July 2021, the CDC advised all people — vaccinated and unvaccinated — to wear masks in public indoor places, in areas with substantial or high transmission of the virus. The CDC has always advised unvaccinated people to mask indoors, and also advises anyone at increased risk to wear a mask indoors, regardless of the level of community transmission. The change in guidance for people who are fully vaccinated was made amidst increasing numbers of infections and hospitalizations across the country.

One factor driving increased infections is the rise of the Delta variant, which spreads more easily than other variants. The Delta variant is now the dominant variant in the US.

We know that people who are fully vaccinated have a much smaller risk of getting sick if they are exposed the Delta variant. While they are also less likely to spread the virus, the Delta variant is more capable than the original virus of getting into cells that line the nose, mouth, and throat. Once these variants get inside the cells, they rapidly make copies of themselves, increasing what is called the viral load. That’s why people who are fully vaccinated can still carry greater amounts of the Delta variant, making it more likely that they could spread the virus to others.

For Many Long Covid Patients Who Were Not Admitted To Hospital Symptoms Come And Go In Three Separate Waves

Heightman says that while 50% of UCLH’s long Covid patients who were not admitted to hospital have improved over the course of a year to the point that they can manage their symptoms alone, the remaining half are still unwell.

Much of the information we have about the long-term prognosis and symptoms experienced by this group of patients has come from a handful of dedicated clinics like Heightman’s around the world, along with the efforts of virtual long Covid communities such as the Patient-Led Research Collaborative .

While half of Heightman’s patients have made a good recovery, others have not been so fortunate. A recent survey from the PLRC painted a bleaker picture. Out of 3,762 long Covid patients, 77% were still experiencing fatigue after six months, 72% were struggling with post-exertional malaise, 55% were suffering from cognitive dysfunction, while 36% of female patients experienced menstrual cycle issues. “My own cycle disappeared for three months,” says Hannah Wei, part of the PLRC leadership team, who herself suffered from long Covid over the past year.

Many long Covid patients report experiencing their symptoms in waves that come and go

But why is it that Covid-19 impacts these patients in this way, and how is it that some people who were first infected a year ago are still yet to recover? One of the major challenges for doctors attempting to treat long Covid is that there are likely to be a variety of underlying triggers or causes, depending on the patient.

Coronavirus Status Report: Harvard Public Health Expert Dr Ashish K Jha Fills Us In On Where We Are Headed

Here’s How Long Coronavirus Symptoms Tend to Last ...

The COVID-19 outbreak has caused markets to collapse and worldwide health systems to become overwhelmed. When there’s a global pandemic, it’s nice to hear from the steady, transparent and yes even reassuring voice of experts on the front lines. We spoke to Dr. Ashish K. Jha, faculty director of the Harvard Global Health Institute. Dr. Jha’s recent appearance on the PBS Newshour caused reverberations throughout the federal and state response system. Here’s his update.

How Have The Vaccines Performed The Real World Are They Working As Well As They Did In Clinical Trials

In a study published online in MMWR, the CDC reported that people who had received both doses of either mRNA vaccine were 90% less likely to get infected with COVID-19 than people who were not vaccinated. In clinical trials, the vaccines were 95% and 94.1% effective.

The MMWR study enrolled 3950 adults who were at high risk of exposure to the virus due to their jobs and followed them for 13 weeks, beginning in mid-December 2020. About 63% of the study participants received both doses of vaccine during the study period and an additional 12% received one dose during the study. Each week, the study participants sent a nasal swab for PCR testing, and they reported any symptoms, allowing the researchers to identify both symptomatic and asymptomatic infections.

A total of 180 COVID-19 infections occurred during the study period. Of these, 161 infections were in people who were unvaccinated, compared to three infections in people who were fully vaccinated. Sixteen people who had received only their first vaccine dose at least two weeks earlier were infected. While this translates to one dose preventing 80% of infections, the study did not measure how well the vaccine protects people who do not get the second dose.

The researchers did not comment on variants, and the study was not designed to measure the effectiveness of the vaccines against them. However, it’s worth noting that several viral variants were circulating during the study period.

Many Long Covid Patients Simply Get Better Over The Course Of Time As Their Body Recovers And Heals

Imaging studies conducted by Japanese scientists have revealed chronic neuroinflammation in a number of ME/CFS patients, while similar microglial disruption is thought to occur in a number of psychiatric disorders like depression and schizophrenia.

As a result, Valeria Mondelli, an immunologist at Kings College London, is advocating trials of anti-inflammatory medications for long Covid patients.

“Either anti-inflammatories like minocycline – an antibiotic which seems to work for patients with higher levels of inflammation in the blood – or cytokine inhibitors, could be potential treatment options,” she says.

David Kaufman, a ME/CFS doctor who has treated around 1,000 patients in Mountain View, California, over the last eight years, feels that long Covid clinicians should also look for evidence of dysfunction in the microbiome, which could be making these patients more vulnerable to suffering long-term problems from the SARS-CoV-2 virus.

“80% of the ME/CFS patients I’ve tested have small intestinal bacteria overgrowth, otherwise as a leaky gut,” Kaufman says. “Because the gut is a major immune organ, this leads them down a road to autoimmune problems.”

There is currently little research on whether Covid-19 vaccines will help to ease the suffering caused by long Covid

What Might Happen In The Fall And Winter When People Move Indoors And Children Are Back In School

“There’s every reason to suspect that SARS-CoV-2 infection rates will be worse in winter as opposed to summertime, because that’s the path we see with other respiratory viruses,” Dowdy says. “ we don’t have evidence yet.” And with so much Delta circulating in both vaccinated and unvaccinated people, we are unwittingly exerting selection pressure for new, more dangerous variants to evolve, Andersen cautions. “This fall and winter I am not sure we will be dealing with Delta. I think we will probably be dealing with a variant we haven’t heard about yet,” he says. “From a viral evolution perspective, it would be foolish not to expect that.”

What Does The Delta Variant Have In Store For The United States We Asked Coronavirus Experts

The United States is standing at a dire inflection point, with pandemic coronavirus cases surging and only 50% of the population fully vaccinated. Driving the latest wave is the highly contagious Delta variant, which according to the Centers for Disease Control and Prevention caused between 80% and 87% of all U.S. COVID-19 cases in the last 2 weeks of July—up from 8% to 14% in early June. The variant’s exceptional infectiousness has driven cases from a 7-day average of 13,500 daily cases in early June to 92,000 on 3 August. At the same time, an internal CDC document that leaked last week says the variant may make people sicker, citing published reports from Singapore and Scotland and a preprint from Canada.

The good news is that severe disease and death are highly unlikely among the vaccinated—and U.S. vaccination rates are beginning to increase once again, if modestly.

How bad will the U.S. surge become, and how long will it take to recede? “Anyone saying they know exactly what is happening is overconfident,” says Natalie Dean, a biostatistician at Emory University. “There is a lot of uncertainty about what will happen in the future, even on a relatively short time scale.” With that proviso, here is what Dean and other scientists closely following the pandemic told Science

Does Deltas Trajectory Influence The Debate Over Whether People Should Receive Booster Doses

Scientists generally agree on the need for immunocompromised people to receive boosters soon, although a go-ahead from U.S. regulators will be needed. Israel is moving ahead with administering a third vaccine dose to people ages 60 and older, and the United Kingdom may soon follow with boosters for older people.

But experts disagree on whether Delta’s emergence calls for an urgent focus on boosters in the general population. Pfizer added fuel to the conversation last week, when it  showing the efficacy of its vaccine declined from 96.2% to 83.7% more than 4 months after full vaccination.

But because the available U.S. vaccines are still highly effective against Delta and the vast majority of serious illness and death is occurring in people who are unvaccinated, “I would strongly prioritize getting more people fully vaccinated than getting booster shots in people,” Dowdy says.

Dean adds that a global view is important: “We live in a world where so many people remain unvaccinated. How do you justify that boost to individuals that have a certain amount of protection?”

World Health Organization Director-General Tedros Adhanom Ghebreyesus threw the organization’s moral authority behind that viewpoint today,  on booster vaccinations through at least September. Confronted with the Delta variant, he said, “We cannot accept countries that have already used most of the global supply of vaccines using even more of it, while the world’s most vulnerable people remain unprotected.”

As The Global Battle Against The Pandemic Continues We Look At What We Know About The Covid


Evidence is mounting that, even as infection numbers increase, the UK’s vaccine programme is successfully breaking the link between COVID-19 infections, hospitalisations and deaths.

Compared to this time last year we know much more about the virus and how to fight it – including what symptoms it causes, how long they last and how effective the vaccines actually are.

Its Not Over Yet: Uncertain Protection From Covid Vaccines Leaves Cancer Patients In Limbo

There are some experts who are more cautious about the timeline. Historian John Barry, who wrote the definitive account of the Spanish flu, “The Great Influenza,” noted there are significant differences between Covid infection and transmission and influenza infection and transmission. The incubation period — the time from exposure to illness — is longer with Covid. People are sick for longer; they’re infectious for longer, too.

“This is like influenza moving in very slow motion,” Barry said. Influenza pandemics have abrupt endings to their waves, with transmission dying out in any given location in a matter of weeks. That has not been the case with Covid. Instead, human behavior — societal shutdowns and reopenings — appear to be driving patterns.

Lipsitch worries that the recent explosive waves in Brazil and India are reason for us to be wary about forecasts that a transition might be near. Both had experienced substantial transmission early in the pandemic, yet have been walloped by second waves triggered by mutated viruses, so-called variants of concern.

“I think we do have to have some account of how it’s taking this whole year with multiple waves and still there’s no real evidence that it’s ending on its own in any country. And I think that a slower natural history is probably a piece of it,” he said. “It’s been niggling at me.”

Mike Ryan, head of the WHO’s Health Emergencies Program, agreed.

Once the covid infection, that is, the acute stage of the disease, is over, for some a new story begins that can last for months, even up to a year.

Can Other Countries Delta Surges Offer Hints About What Will Happen In The United States

In India, where the Delta variant was first identified, a massive, Delta-driven wave began in late March and receded by late June, even though mask wearing was spotty and less than 1% of the population was vaccinated as the wave began. In the United Kingdom, a surge that began in early June peaked in mid-July and is now rapidly receding, although daily cases are still many times what they were before the Delta variant took over.

But assuming the U.S. surge will recede as quickly as the one in the United Kingdom did may be a mistake. In that country, vaccine uptake has been much higher than in the United States. Former CDC Director Tom Frieden, president of the nonprofit Resolve to Save Lives, cautioned yesterday in a tweet that the number of unvaccinated Americans could make the U.S. surge “much deadlier” than the United Kingdom’s.

The US Covid surge continues, but hospitalizations are increasing far faster here than they ever did during the UK’s surge. With so many unvaccinated Americans, our surge will be MUCH deadlier.

I Am Pregnant And Plan To Eventually Breastfeed My Baby Is It Safe For Me To Get A Covid

In August 2021, the CDC gave its clearest recommendation to date that women who are pregnant, thinking about becoming pregnant, or who are breastfeeding should get vaccinated against COVID-19. The American College of Obstetrics and Gynecology and the Society for Maternal-Fetal Medicine also agree that all pregnant and breastfeeding individuals should be vaccinated. The World Health Organization recommends use of a COVID-19 vaccine in pregnant women when the benefit to an individual outweighs the potential vaccine risks. Experts, including the WHO, believe it is most likely safe to get a COVID-19 vaccine if you’re breastfeeding. Similar to any decision regarding over-the-counter medications and supplements during pregnancy, your own doctor is in the best position to advise you based on your personal health risks and preferences.

Here are some factors to consider. First, although the actual risk of severe COVID-19 illness and death among pregnant individuals is very low, it is higher when compared to nonpregnant individuals from the same age group. In addition, COVID-19 increases risk for premature birth, particularly for those with severe illness, and possibly also for other undesirable pregnancy outcomes. Transmission of the virus from mother to baby during pregnancy is possible, but it appears to be a rare event.

Is There Any Difference In Vaccine Induced Immunity Between The First And Second Doses

It’s difficult to get a sense of the entire immune response after one dose of vaccine versus two, but multiple studies have investigated antibody levels at different stages of dosing. One preprint study from researchers at University College London involving more than 50 000 participants found that 96.4% were antibody positive one month after their first dose of either the Pfizer or AstraZeneca vaccines, and 99.1% were antibody positive between seven and 14 days after their second dose.15 Median antibody levels changed slightly up to two weeks after the second dose, at which point they rocketed.

Another study, also a preprint by researchers in the UK, evaluated the difference in peak antibody levels among 172 people over 80 who received the Pfizer vaccine.16 Those who had no previous record of covid-19 infection had 3.5 times more antibodies at their peak if they received their second dose 12 weeks later rather than three weeks later. However, median T cell levels were 3.6 times lower in those who had the longer dosage interval . This again shows how early we are in our understanding of the virus and immunity to it.

Is It Safe To Use Steroids To Control Allergy And Asthma Symptoms During The Covid

Yes, it is safe to use corticosteroid nasal sprays to control nasal allergies or inhaled corticosteroids to control asthma symptoms during the COVID-19 pandemic.

The American College of Allergy, Asthma and Immunology issued a statement emphasizing the importance of controlling allergy and asthma symptoms during the pandemic. They said there is no evidence that intranasal or inhaled corticosteroids increase the risk of getting the COVID-19 infection or lead to a worse outcome if you do get infected.

The ACAAI statement was a response to concerns over reports warning against the use of systemic steroids to treat hospitalized COVID-19 patients with specific respiratory complications. However, those reports did not refer to healthy individuals using corticosteroid nasal sprays or inhalers to manage allergies or asthma.

Symptoms Spread And Other Essential Information About The Coronavirus And Covid

As we continue to learn more about coronavirus and COVID-19, it can help to reacquaint yourself with some basic information. For example, understanding how the virus spreads reinforces the importance of prevention measures. Knowing how COVID has impacted people of all ages may reinforce the need for everyone to adopt health-promoting behaviors. And reviewing the common symptoms of COVID-19 can help you know if it’s time to self-isolate.

What Is ‘viral Persistence’ And How Does That Affect The Course Of The Disease

Sometimes the coronavirus sticks around longer than expected—and scientists are still trying to figure out why that happens in some patients, how it varies by individual, and exactly how long the virus stays alive inside the body. This is known as viral persistence, and it affects how long someone is contagious and therefore how long they should stay in isolation.

Do Adults Younger Than 65 Who Are Otherwise Healthy Need To Worry About Covid

Yes, they do. Although the risk of serious illness or death from COVID-19 increases steadily with age, younger people can get sick enough from the disease to require hospitalization. And certain underlying medical conditions may increase the risk of serious COVID-19 for individuals of any age.

Everyone, including younger and healthier people, should get the vaccine once they are eligible, to protect both themselves and their community. Vaccines offer excellent protection against moderate to severe disease, hospitalization, and death. While you’re also less likely to spread the virus once you’ve been vaccinated, the Delta variant is more capable than the original virus of getting into cells that line the nose, mouth, and throat. Once these variants get inside the cells, they rapidly make copies of themselves, increasing what is called the viral load. That’s why people who are fully vaccinated can still carry greater amounts of the Delta variant, making it more likely that they could spread the virus to others.

Where Are The Newest Covid Hot Spots Mostly Places With Low Vaccination Rates


“And unfortunately, those two attributes tend to coincide within the same people and within the same population subgroups,” Goldman says. In other words, many of the same people who don’t want to get a vaccine also don’t want to wear a mask.

Graduates participate in a University of Southern California commencement ceremony at the Los Angeles Memorial Coliseum in May.

As a result, Goldman says, we’re likely to see continued transmission of the virus in the U.S., concentrated in the areas with lowest rates of vaccination.

The current vaccines are highly effective against COVID-19, including the delta variant. That means vastly different outcomes for those who are vaccinated and those who aren’t. Last month, for example, 92 people died of COVID-19 in Maryland. All of them were unvaccinated.
