Federal health officials are investigating emerging reports that the Moderna coronavirus vaccine may be associated with a higher risk of a heart condition called myocarditis in younger adults than previously believed, according to two people familiar with the review who emphasized the side effect still probably remains uncommon.
Since Americans first began rolling up their sleeves for coronavirus vaccines, health officials have said that those who are immunized are very unlikely to become infected, or to suffer serious illness or death. But preliminary data from seven states hint that the arrival of the Delta variant in July may have altered the calculus. Breakthrough infections are also likely to be most severe among older adults or those who have conditions like obesity or diabetes.
For more than a year, we’ve worked with North Carolina school districts and charter schools, studying the rate of new Covid cases, the efficacy of mitigation measures such as masking and the increased risks of participating in school-sponsored sports. We have learned a few things for certain:
The agency is reviewing several dozen reports that teenagers and young adults may have developed myocarditis after vaccination, officials said. But the agency has not determined whether the vaccine caused the condition.
The U.S. State Department said on Monday it will boost its "Do Not Travel" guidance to about 80% of countries worldwide, citing "unprecedented risk to travelers" from the COVID-19 pandemic.
Five South Koreans have died in the last two days after receiving the Covid-19 vaccine produced by AstraZeneca, sparking a presidential response and contributed to rising global concerns about the dose. According to local media reports, the five who died – two on Wednesday and three on Thursday – all had significant pre-existing medical conditions.
Doctors across the country have been seeing a striking increase in the number of young people with the condition Braden had, which is called Multisystem Inflammatory Syndrome in Children or MIS-C. Even more worrisome, they say, is that more patients are now very sick than during the first wave of cases, which alarmed doctors and parents around the world last spring.
It appears science may have found the Covid-19 pandemic’s off-ramp, but if we’re not careful, we could fail to take full advantage of it. This article discusses what could go wrong and how to prevent it.
Using this interactive map you can see the risk level of attending an event, given the event size and location. You can reduce the risk that one case becomes many by wearing a mask, distancing, and gathering outdoors in smaller groups.
Even Though there is promising news about vaccines, and Pfizer has announced a vaccine that is 90% effective, scientist say what the vaccine is effective against is going to matter a lot for the timeline of the pandemic.
They made an experiment by releasing droplets in a room to see how it spreads. They found that people in front of the room are more susceptible and at higher risk in a properly ventilated room. In a poorly ventilated room the entire room is at risk.
Passengers sat in window seats in the middle of an economy class cabin on a Qantas Airways flight in March were most at risk from contracting coronavirus, according to research by Australian scientists into that particular trip.
A flurry of recent studies has shown that people with extra weight are more susceptible than others to severe bouts of disease. And experiments in animals and human cells have demonstrated how excess fat can disrupt the immune system.
Looking at the records of over 73 million patients in the US, of whom 12,033 had Covid-19, the study found those who had recently been diagnosed with a substance use disorder were significantly more at risk of Covid-19 than the average population.
Is it safe to fly with the coronavirus still circulating? That depends partly on where you are. But while hard evidence is scarce, it appears the risk of being infected with covid-19 during a flight is relatively low.
For a world crippled by the coronavirus, salvation hinges on a vaccine. But in the United States, where at least 4.6 million people have been infected and nearly 155,000 have died, the promise of that vaccine is hampered by a vexing epidemic that long preceded Covid-19: obesity.
One of the first school districts in the country to reopen its doors during the coronavirus pandemic did not even make it a day before being forced to grapple with the issue facing every system actively trying to get students into classrooms: What happens when someone comes to school infected?
“Every health system, every public health department, every jurisdiction really has their own ways of going about things,” says Caitlin Rivers, a senior scholar at the Johns Hopkins Center for Health Security. “It's very difficult to get an accurate and timely and geographically resolved picture of what's happening in the US, because there's such a jumble of data.”
A study from China found 16% of household contacts developed COVID-19, and that spouses of the index case (meaning the first person to spread it in that cluster) were more likely to get infected than other family members.
Of the 100 COVID-19 patients, 78 had structural changes to their hearts. Within that group, 76 had a biomarker that is typically found in patients who had a heart attack, and 60 had heart inflammation, called myocarditis. The patients were all “mostly healthy … prior to their illness,” the researchers said.
In addition to impairing the immune and vascular systems and triggering cerebrovascular and neurological dysfunction, smoking and vaping often worsen the outcomes for patients who contract influenza or other respiratory or pulmonary diseases.
A man who says he had a “mild case” of COVID-19 several months ago just revealed that he’s still having heart issues following his recovery from the virus. Anthony Smith, vice president of digital media company NationSwell, shared his story in a Twitter thread that’s now gone viral.
Neurologists are on Wednesday publishing details of more than 40 UK Covid-19 patients whose complications ranged from brain inflammation and delirium to nerve damage and stroke. In some cases, the neurological problem was the patient’s first and main symptom.
“The idea that ‘I’m young, I’ll be fine’ is not an idea that we can completely subscribe to,” said Dr. Utibe Essien, a physician and health equity researcher at the University of Pittsburgh.Amanda Kloots, Mr. Cordero’s wife, has said that he had no known pre-existing conditions that might have worsened the course of his disease.
The United States is once again at risk of outstripping its COVID-19 testing capacity, an ominous development that would deny the country a crucial tool to understand its pandemic in real time.
As the pandemic grew from an outbreak affecting thousands in Wuhan, China, to some 10 million cases and 500,000 deaths globally as of late June, the list of symptoms has also exploded. The Centers for Disease Control and Prevention constantly scrambled to update its list in an effort to help clinicians identify likely cases.
Soaring cases of the coronavirus are forcing cities and states across the country to halt plans to restart their economies and even reimpose earlier limits on public life, increasing worries that premature reopenings could lead to a second round of closures.
New known virus cases were on the rise in 23 states on Monday as the outlook worsened across much of the nation’s South and West. Hospitalizations for the coronavirus reached their highest levels yet in the pandemic in Arizona and Texas, and Missouri reported its highest single-day case totals over the weekend.
As scientists have learned more about COVID-19, it has become clear that so-called superspreader incidents—in which one person infects a disproportionate number of other individuals—have played an oversized role in the transmission of the virus that causes the disease.
“Meat is probably not a big risk,” said said Angela L. Rasmussen, PhD, a virologist in the faculty of the Center for Infection and Immunity at the Columbia Mailman School of Public Health. “There is no evidence of food borne transmission,” Rasmussen added.
The risk of severe COVID-19 infection is more common in those with high blood pressure, diabetes and obesity. This raises the question of whether the gut microbiome has a role in dictating COVID-19 severity.
In the face of the virus emergency, research standards have been relaxed to encourage faster publication and mistakes become inevitable. This is risky. Ultimately, if expert advice on the pandemic turns out to be wrong, it will have dire consequences for how reliable scientific evidence is treated in other policy areas, such as climate change.
New coronavirus infections hit record highs in six U.S. states on Tuesday, marking a rising tide of cases for a second consecutive week as most states moved forward with reopening their economies.
In America, Coronavirus hasn’t slowed one bit. See that line above? In Europe, it’s flattened out. But in America, the worst case scenario is now about to come true. Since states are reopening, since the government has no plan, and as a nation, America seems to simply have… given up on it…
Variations at two spots in the human genome are associated with an increased risk of respiratory failure in patients with Covid-19, the researchers found. One of these spots includes the gene that determines blood types. Having Type A blood was linked to a 50 percent increase in the likelihood that a patient would need to get oxygen or to go on a ventilator, according to the new study.
We need to find out how human behaviour is changing in response to COVID-19, how this affects demands for food, energy, the Internet and transportation, and whether these altered demands are likely to increase or decrease people’s susceptibility to the effects of extreme weather.
This author puts the risks of dying from COVID-19 into a metric called "micromort", which measures a one-in-a-million chance of dying. The micromorts allows one to easily compare for example the risk of dying from skydiving (7 micromorts per jump), or dying under general anesthesia (5 micromorts).
Anthony S. Fauci, the nation’s top infectious-disease expert, warned of “suffering and death that could be avoided” and of further economic damage if states reopen too quickly and said the U.S. death toll from the coronavirus is probably higher than the 80,000 reported.
Several months into the pandemic, medical experts say that Asthma hasn't been a significant risk factor. Even though CDC recommended at the beginning of the pandemic that COVID-19 patients should not be treated with corticosteroids, because steroids increase the need for ventilation, length of illness and chance of dying, this did not apply to people who are already on steroids for underlying conditions.
Other viruses can affect the heart, but experts say that COVID-19 can cause cardiac complications that are a major cause for concern, especially among those with preexisting heart disease. Although experts don't yet have conclusive data on the percentage of patients who have heart damage as a result of COVID-19 infections, estimates run as high as 25 or 30 percent.
WHO says governments should not issue so-called immunity passports" as a way of easing lockdowns. No evidence people who develop antibodies after recovering are protected against a second infection. WHO warns that such move could actually increase the spread of the virus transmission. People who assumed they were immune could stop taking precautions.
In January, at a restaurant in Guangzhou, China, one diner infected with the novel coronavirus but not yet feeling sick appeared to have spread the disease to nine other people. One of the restaurant’s air-conditioners apparently blew the virus particles around the dining room.
Obesity may be one of the most important predictors of severe coronavirus illness, new studies say. It’s an alarming finding for the United States, which has one of the highest obesity rates in the world.Some 42 percent of American adults — nearly 80 million people — live with obesity. That is a prevalence rate far exceeding those of other countries hit hard by the coronavirus, like China and Italy.
Only 29% of Americans have the luxury of social distancing. The other 79% have a more uncertain situation. This post presents a visual chart of risk score by occupation. The methodology is absed on contact with others, physical proximity and exposure of disease infection.
Is the initial dose of SARS-CoV-2 (the virus that causes COVID-19) related to the disease severity? At the moment, we just don't know. The only way to answer this question definitively is with "experimental challenge studies", which involves intentionally infecting healthy volunteers in order to study diseases and their treatments.
There are rumors around the Internet that UV lights can cure Covid-19, but the truth is more complicated. Experts say that there’s only one type of UV that can reliably inactivate Covid-19 – and it’s extremely dangerous.
