During 24 days in February and March, 112 people were infected with the Covid-19 virus in South Korea after participating in or associating with participants in Zumba classes, according to a sobering new epidemiological study published in Emerging Infectious Diseases.
While it’s likely people develop some immunity after being infected with the coronavirus, experts still don’t know whether you need a certain amount of antibodies to fight off another infection. And even if you do have the right amount, it also isn’t clear yet how long its protection lasts.
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.
K sheds light on the variation behind R. “Some [infectious] people might generate a lot of secondary cases because of the event they attend, for example, and other people may not generate many secondary cases at all,” said Dr Adam Kucharski. “K is the statistical value that tells us how much variation there is in that distribution.”
Neuroscientist Karl Friston, of University College London, builds mathematical models of human brain function. Lately, he’s been applying his modelling to Covid-19. He says, our approach, which borrows from physics and in particular the work of Richard Feynman, goes under the bonnet. It attempts to capture the mathematical structure of the phenomenon – in this case, the pandemic – and to understand the causes of what is observed.
Data shows us that mysterious symptoms attributed to COVID-19, like coronavirus related strokes and Covid toes, are symptoms of an impairment in blood circulation. Add in the fact that 40% of the deaths from Covid-19 are related to cardiovascular complications, the disease starts to look like a vascular infection.
Since the coronavirus outbreak, all three networks have worked to promote appropriate sources of health information and pull down content that could harm users. However, they have traditionally shied from removing false information that is politically charged. As health misinformation becomes increasingly politicized, they may be forced to take a stance.
One of the consequences of COVI-19 is that companies have realized that they can forego expensive office space if they let people work for home. This is a direction that will affect other aspects of our society
A story about testing, contract tracing and controlling the spread of the virus. Cultural taboos and privacy issues can be a detriment to stopping the spread of the virus as we learn from this story
Communist-run Cuba said this week that use of two drugs produced by its biotech industry that reduce hyper-inflammation in seriously ill COVID-19 patients has sharply curbed its coronavirus-related death toll.
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).
A third of Covid-19 patients are asymptomatic and 0.4% of those who get sick will die, CDC says. The agency cautions that those numbers are subject to change as more is learned about Covid-19, and it warns that the information is intended for planning purposes.
There will be many changes to dining out, like shorter menus, and servers wearing masks and surgical gloves.We don't know how this will effect the industry, we know that many resturants who have closed will never come back.
Many people are relying on food delivery in the times of COVID-19. The question here is how worried do we have to be to contract the virus from plastic bags, carton boxes and the food delivered.
The Centers for Disease Control and Prevention has finally issued full interim guidance on how schools and other establishments can safely open during the covid-19 pandemic, and below are all the recommendations for schools and camps.
There have been no recent studies on how long the virus survives in pools, oceans or lakes, however studies on other coronaviruses show us that the virus does not survive in chlorine waters, however there are other dangers.
There is a value to disinfecting public transportation like subway cars, but spraying the streets is not very effective, and the possibility of contracting the virus from street floors is very low.
The preponderance of research suggests warmer weather might have a small impact on slowing the spread of coronavirus, but the summer itself certainly won't end the historic pandemic.
Chinese doctors are seeing the coronavirus manifest differently among patients in its new cluster of cases in the northeast region compared to the original outbreak in Wuhan. Patients found in the north east appear to carry the virus for a longer period of time and take longer to test negative.
Coronavirus chaos has spurred a grow your own food movement and space-age hydroponic is rising to meet it. Seems like new opportunities to reinvent ourselves never cease to exist!
Language matters. This author critiques the use of War metaphors in dealing with pandemics. Author reminds us that at war we require command and control, rather than the spontaneous volunteerism we have seen with self-isolation and self quarantine.
Recently some children are displaying new life threatening, pediatric inflammatory syndrome. Children in Europe and United States are being hospitalized for this mysterious illness, which can harm kids hearts and other organs, often requiring intensive care.
In this report we learn of symptoms like rashes, glossy eyes, stomachaches, in young adults as a result of coronavirus. The young adult had developed a tennis-ball size lymph node, raging fever, racing heartbeat, and dangerously low blood pressure after 14 days.
There is growing evidence that the virus causes a far greater array of symptoms than was previously understood. And that its effects can be agonisingly prolonged: in Garner’s case for more than seven weeks. The professor at the Liverpool School of Tropical Medicine says his experience of Covid-19 featured a new and disturbing symptom every day, akin to an “advent calendar”.
The FDA has received at least 15 reports that suggest Abbott Labs coronavirus tests are inaccurately telling patients that they do not have the virus, FDA said in a Thursday press release citing early data. These tests have been widely distributed by the federal government in response to the pandemic.
Infectious disease physician and vaccination specialist Dr. Jonas Nilsen tells Romper that while The Centers for Disease control and Prevention (CDC) has put out a mandate stating that "the chance of COVID-19 to manifest in swimming pools, spas, jacuzzis, etc. is very low as they are treated with chlorine and bromine," it's the lack of social distancing in and around the pools that is dangerous.
Where people travel and how long they stay away from home can be measured with smartphone location data. But the increasingly popular movement maps derived from this data don’t reveal how well people maintained social distancing once they reached their destinations
Osang Healthcare Co, the first South Korean maker of coronavirus test kits to win preliminary approval from the U.S. Food & Drug Administration, is ready to ship kits that can test 100 million people in the United States, an executive said on Friday.
Telemedicine company Hims says it will start selling saliva tests for SARS-CoV-2 that you can take at home from RUCDR Infinite Biologics, an organization within the Rutgers University Genomics Laboratory. Patients must be exhibiting symptoms to qualify for a test.
Here you find a list of symptoms caused by coronavirus. These symptoms may appear 2-14 days after exposure to the virus. Additionally find emergency warning signs if you are infected and when you should be seeking medical help.
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.
The greater Seattle Coronavirus Assessment Network—or SCAN—is a first-of-its-kind disease surveillance platform for COVID-19 that allows participants to use a self-swab test to collect their own nasal samples and send them to a lab without leaving home. As a surveillance program, SCAN’s goal isn’t to test every person or serve as a replacement for medical care.
In order to get infected you need to get exposed to an infectious dose of the virus; based on infectious dose studies with other coronaviruses, it appears that only small doses may be needed for infection to take hold. Learn where and how your risks increase.
New York Gov. Andrew Cuomo (D) said Sunday that three New York children have died and 73 have become gravely ill with an inflammatory disease tied to COVID-19. The illness, pediatric multisystem inflammatory syndrome, has symptoms similar to toxic shock or Kawasaki disease. Doctors, emphasized parents should not panic. The vast majority of those younger than 18 who are infected with the coronavirus have mild symptoms or none at all.
Wuhan has ordered officials to test its entire population of 11 million people after the central Chinese city where the coronavirus pandemic began reported new infections for the first time since its lockdown was lifted.
A five-hour online course created by Johns Hopkins Bloomberg School of Public Health could become the backbone of the country's contact tracer training program. The class, which rolled out Monday, offers online instruction to anyone who wants to learn the basics of contact tracing: the process of identifying and isolating people who have been infected with COVID-19 and their close contacts.
Today, there is widespread recognition the novel coronavirus is far more unpredictable than a simple respiratory virus. Often it attacks the lungs, but it can also strike anywhere from the brain to the toes. Many doctors are focused on treating the inflammatory reactions it triggers and its capacity to cause blood clots, even as they struggle to help patients breathe.
When will the Covid-19 pandemic end? And how? According to historians, pandemics typically have two types of endings: the medical, which occurs when the incidence and death rates plummet, and the social, when the epidemic of fear about the disease wanes.
The main job is to contact people who have been exposed to the coronavirus by a person who has tested positive. Some people are a little suspicious. Some people hang up after I ask for their date of birth and address. I understand that, the mistrust of the government, having grown up under communism.
Imagine being told to inhale a nasal spray full of coronavirus. More than 14,000 people in the U.S. and elsewhere are putting their names forward to do so. They are volunteering for what's called a "human challenge trial," an ethically controversial way to test vaccines that would deliberately infect people with a virus that has killed over 270,000 people worldwide and has no cure.
As the coronavirus spreads around the world, there are concerns that it will mutate into a form that is more transmissible, more dangerous or both, potentially making the global health crisis even worse. What do we know about the way the virus is evolving?
In some places, “double-bubbling” is becoming official policy: households are being encouraged to buddy up for the sake of variety and mental health. But negotiating to become part of someone else’s intimate circle in the midst of a pandemic is fraught with dangers both medical (what if you inadvertently infect one another?) and social. (What if you have a falling out? Whom do you pick? What if they don’t pick you?).
I’ve hardly moved from this couch in weeks, but right now my heart rate monitor says I’m at 132. That’s double my normal. That’s like if I’m climbing a mountain. How come? Nobody knows. Nobody ever knows. And why has my fever been spiking again? Do I need to go back to the ER?
New coronavirus infections are accelerating again in Germany just days after its leaders loosened social restrictions, raising concerns that the pandemic could once again slip out of control.
Get detailed statistics on mortality rate for any and all countries around the world. The charts include mortality risk, fatality rate, fatality rate by age, by health conditions and compared to other diseases.
Since the late 1990s, when an outbreak of HIV infections threatened to shutter the multibillion-dollar industry, the mainstream porn community has implemented procedures that require all performers to be tested for HIV and a host of other sexually transmitted infections every 14 days before they can be cleared to work.
The immediate effects of the disease are devastating.But what has confronted doctors and patients alike since American hospitals began to fill up in March has been another, deeply sobering prospect: that of long-term, maybe permanent organ damage among those who contract severe COVID-19 infections.
We fact-checked eight of Mikovits’ most misleading claims from the video. They span from conspiracies about the origin of the coronavirus to falsehoods about wearing a face mask.
The analysis of the Pandemic video offers some insight into claims made against Dr Fauci, more specifically the claim that Dr. Fauci sent threatening letters to her and about him profiting from patents and COVID-19 payments
Researchers are beginning to test homeless individuals in the United States for the virus that causes COVID-19 — and are discovering that the situation is out of control: tests are rare and outbreaks are spreading below the radar.
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.
The coronavirus SARS-CoV-2 is often spread through sneezes and coughs, but it also leaves the human body through our waste. Scientists around the world are now testing sewage for the virus, using it as a collective sample to measure infection levels among thousands of people.
Why are there so few antivirals? The answer boils down to biology, and specifically the fact viruses use our own cells to multiply. This makes it hard to kill viruses without killing our own cells in the process.
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.
There’s a lot of work being done on antibodies for the coronavirus and on the protein domains they recognize. This of course has bearing both on the idea of monoclonal antibody therapies and for the vaccines that are in development, so let’s have a look at the new data.
A genetic analysis of samples from more than 7,500 people infected with COVID-19 suggests the new coronavirus spread quickly around the world late last year and is adapting to its human hosts, scientists said on Wednesday.
Vaccines to prevent Covid-19 infection are hurtling through development at speeds never before seen. But mounting promises that some vaccine may be available for emergency use as early as the autumn are fueling expectations that are simply unrealistic, experts warn.
A research paper from scientists at Los Alamos National Laboratory, not yet peer-reviewed, reports that one strain of the novel coronavirus has emerged in Europe and become dominant around the planet, leading the researchers to believe the virus has mutated to become more contagious The bold hypothesis, however, was immediately met with skepticism by many infectious-disease experts, and there is no scientific consensus that any of the innumerable mutations in the virus so far have changed the general contagiousness or lethality of covid-19, the disease caused by the coronavirus.
As the world comes to terms with how governments have responded to today's coronavirus pandemic, some are looking to history to guide them. Chief among those lessons is the need "to have proper precautions in place," and not to try and hush it up or try and deny its existence. Then it has fatal consequences for many, many people.
Learn specific, easy-to-follow, science-based recommendations for limiting the transmission of the coronavirus while operating a wide variety of businesses, including restaurants, retail outlets, and hair and nail salons.
Children don't seem to be inflicted by the common respiratory symptoms but similar to a rare childhood illness called Kawasaki disease which can be lead to inflammation of blood vessels, especially the coronary arteries.
To slow the spread of COVID-19, state and local officials implemented a range of non-pharmaceutical interventions, like social distancing and school closures. This policy evaluation tool helps decisionmakers weigh the public health and economic consequences of different approaches.
In a significant medical breakthrough, Israel's Institute for Biological Research Institute (IIBRI) has wrapped up the development of a potential treatment for the coronavirus disease. The scientists say they have identified an antibody that neutralizes SARS-CoV-2 in vitro or outside of a living organism.
To prevent another spike in cases, public health workers will perform the difficult and sometimes tedious process of interviewing people diagnosed with Covid-19, finding out who they have recently been in close physical contact with, and then informing those people of their potential exposure and advising them to self-isolate and get tested.
This is a report from a leaked government report. Its is not sure how these predictions are made, and whether it is because of reopening. The white house officials have been relying on other models (than CDC) to make decisions on reopening. The estimates here are based on premature relaxation of restrictions.
This visualization provides weekly data on excess deaths by jurisdiction of occurrence. Counts of deaths in more recent weeks are compared with historical trends to determine whether the number of deaths is significantly higher than expected.
More information is needed after a French study suggested nicotine might play a role in preventing some illness from the coronavirus. Nicotine is not thought to attack sars-cov-2 directly. It may, however, play an indirect role that involves a cell-membrane protein called ace2, to which the virus attaches itself in order to gain access to a cell. Some researchers suspect that nicotine binds to ace2 as well, and that this makes it harder for the virus to do so alongside it.
Sir John Bell, the Regius Professor of Medicine at Oxford University, said Sunday that researchers at the university working on a potential vaccine for the coronavirus would likely have an idea of its efficacy by June. Bell called the chances of success in developing a vaccine “pretty good,” adding “we are gradually reeling it in, bit by bit and as every day goes by, the likelihood of success goes up.”
The purpose of the Coronavirus in Kids (COVKID) Tracking and Education Project is to monitor and compile epidemiologic surveillance data on COVID-19 in children and teens. We aim to present timely data in formats that are accessible and useful for clinicians, public health practitioners, policymakers, elected officials, and journalists.
A number of reported cases of coronavirus patients relapsing after overcoming the disease were actually due to testing failures, South Korean scientists say. Researchers at the South Korean centre for disease control and prevention (CDC) now say it is impossible for the COVID-19 virus to reactivate in human bodies.
IN THE U.S., the vast majority of serious Covid-19 cases — and eight out of 10 deaths — occur in people who are at least 65. Yet newly tabulated data show that the virus is also affecting young people across the country — and in very rare cases, killing them. The CovKid project estimates that the total number of children infected with the coronavirus in the U.S. is now at least 478,000.
As epidemiologists attempt to scope out what Covid-19 has in store for the U.S. this summer and beyond, they see several potential futures, differing by how often and how severely the no-longer-new coronavirus continues to wallop humankind.
Facebook's Covid-19 misinformation campaign pulls from several psychology studies. The problem: The researchers behind some of those papers and outside experts say Facebook appears to be interpreting the findings incorrectly — and their approach could be running counter to the goal of tamping down on runaway misinformation.
Before the coronavirus outbreak, Dr. Lindy Fox, a dermatologist in San Francisco, used to see four or five patients a year with chilblains — painful red or purple lesions that typically emerge on fingers or toes in the winter. Over the past few weeks, she has seen dozens.
On Wednesday, researchers announced that they had “positive data” in regards to a potential treatment for COVID-19. Clinical trials for Gilead Sciences’ antiviral drug remdesivir, which was developed to treat Ebola, showed a “clear-cut positive effect in diminishing time to recover,” according to Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases.
If we are indeed in the midst of a war against an invisible enemy, a contact-tracing offensive — launched by both an army of human tracers and an arsenal of technological tools — will be a big part of the key to winning. In the U.S., the most likely scenario for widespread, tech-enabled contact tracing lies with work done by Google and Apple.
Dr. Barzin explains that muscle pain that results from a viral infection is caused by damage to the muscle fibers from the virus itself. The virus also triggers an inflammatory response within your body—through inflammatory cytokines that essentially signal the immune system to get to work—that can cause abnormal tissue breakdown.
How countries cope with the new coronavirus depends on more than hospital beds and income levels, the United Nations said on Wednesday, highlighting forgotten factors like internet access and reliance on tourism.
The problem, experts say, is that diagnostic testing remains so limited that a second surge of cases could silently build. The Trump administration’s goal of conducting 2 million tests a week is below what most experts say is needed to adequately track the virus, and that plan won’t be in place until at least the end of May.
The consensus so far is that the virus, although very contagious, spreads through respiratory droplets generated when people breathe, speak or cough and doesn’t infect people through particles that can linger in the air for hours, in the way that measles and some other viral diseases can.
Brits express more apprehension about easing the lockdown than any other major country, according to a recent Ipsos MORI poll that surveyed some 28,000 people across 14 different countries. That includes places like the US and Italy, which have both a higher number of Covid-19 deaths and confirmed coronavirus cases.
Hologic, a maker of diagnostic tests, said Wednesday that it is launching a new test for Covid-19 and that it could produce 1 million of them a week, a pace that would significantly expand testing capacity in the United States.
A pet dog in North Carolina has tested positive for SARS-CoV-2 — the virus that causes COVID-19 in humans — and is believed to be the first dog in the U.S. to have tested positive for the virus, Duke Health confirmed to TIME. The dog belonged to a family participating in Duke’s Molecular and Epidemiological Study of Suspected Infection (MESSI), an ongoing research study, which examines how the body responds to infection.
The Reuters/Ipsos opinion poll, conducted from April 15 to 21, surveyed 4,429 adults about their interest in attending concerts, movie theaters, amusement parks, and sporting events before a vaccine was developed. Fifty-five percent of participants said movie theater screenings and live concerts should not resume until a vaccine was available.
The battle against the mental health consequences of the coronavirus pandemic is just beginning. Governments and researchers are mapping how best to prevent the predicted rise in mental health issues we face in coming months and beyond.
