Compared to existing methods for Covid-19 detection, RAPID is inexpensive and…
A major study from the Washington University School of Medicine details numerous long-term effects of COVID-19, pointing to massive health burden.
Scientific and public health experts have been raising the alarm for decades, imploring public officials to prepare for the inevitability of a viral pandemic. Infectious epidemics seemingly as benign as "the flu" and as deadly as the Ebola virus provided ample warning, yet government officials seemed caught off guard and ill prepared for dealing with Covid-19.
This FAQ from the American College of Allergy, Asthma and Immunology is provided to help answer patient questions about COVID-19 vaccines. These recommendations are based on best knowledge to date, but could change at any time, pending new information and further guidance from the FDA or CDC.
As the pandemic has continued to spread globally, studies indicate the COVID-19 virus may be contained in aerosols that can be generated and spread through breathing, coughing, sneezing, or talking by infected individuals. Researchers are increasingly focused on developing tools and methods to assist in decontaminating surfaces and spaces.
According to current studies, the Covid-19 disease which is caused by the SARS-CoV-2 coronavirus comprises at least five different variants. These differ in how the immune system responds to the infection. Researchers from the German Center for Neurodegenerative Diseases (DZNE) and the University of Bonn, together with other experts from Germany, Greece and the Netherlands, present these findings…
Nearly twice as many people were admitted to hospital for Covid-19 at the height of the pandemic than were for influenza at the peak of the 2018/2019 flu season, a study of French national data published in The Lancet Respiratory Medicine journal has found (Covid-19, 89,530 patients vs influenza, 45,819 patients).
Cold Spring Harbor Laboratory (CSHL) scientists developed the world’s first mobile genome sequence analyzer, a new iPhone app called iGenomics. By pairing an iPhone with a handheld DNA sequencer, users can create a mobile genetics laboratory, reminiscent of the “tricorder” featured in Star Trek.
Germany’s lack of diagnostic ability led to significantly underestimation of its own as well as global Covid-19 infection levels during the first wave. Now, however, improved testing and diagnosis of the condition more realistically reveal nearer 20,000 new cases a day across the country, according to Professor Hendrik Streeck, one of the country’s leading virologists. Speaking at a virtual…
A UK biotech laboratory has used mass spectrometry in a new approach to coronavirus testing. MAP Sciences developed a gargle test, which collects samples from the back of the throat, and avoids the unpleasant sensation of the current PCR (polymerase chain reaction) swab tests. From there, the sample is tested for coronavirus using mass spectrometry (MS) with high levels of accuracy.
Measures to reduce the spread of Covid-19 through non-pharmaceutical interventions (NPIs) such as mask wearing and social distancing are a key tool in combatting the impact of the ongoing coronavirus pandemic. These actions also have greatly reduced incidence of many other diseases, including influenza and respiratory syncytial virus (RSV).
Although uncommon, sudden permanent hearing loss seems to be linked to COVID-19 infection in some people, warn doctors, reporting the first UK case in the journal BMJ Case Reports. Awareness of this possible side effect is important, because a prompt course of steroid treatment can reverse this disabling condition, they emphasise. Sudden hearing loss is frequently seen by ear, nose and throat…
It is only 120 millionths of a millimetre in size but can bring entire countries to a standstill: the Corona virus. Even if it were to disappear one day, viral infections will still be among the most frequent and difficult-to-treat diseases in humans. Even decades of research have only produced a few standardized vaccines and strategies for treatment to combat just a small number of viruses. Nor…
As COVID-19 infections begin to rise again, a novel testing strategy proposed by researchers at the University of Oxford at the start of the pandemic has become urgent once again. The strategy aims to bring the virus’s reproduction number (‘R’) down to below 1, by concentrating testing resources on particular groups in the population that are most likely to spread the infection to others,…
More than 32,000 people from over 160 countries registered for The Alzheimer’s Association International Conference (AAIC 2020) in July. This largest and most influential international conference on dementia science had to be held virtually this year, when important highlights were aired. The ability to identify individuals at high risk of developing Alzheimer’s Disease (AD), or at early…
Researchers predict that COVID-19 will likely become seasonal, waning in the summer and prevalent in the winter. But, only once herd immunity is achieved through natural infection or vaccinations. Until then, COVID-19 will be here year-round.
Contrary to expectations, the risk of COVID-19 infection among hospital staff at the height of the coronavirus pandemic was lowest among intensive care clinicians, reveals a study of one major UK medical centre, published in the journal Thorax.
Rhinovirus, the most frequent cause of common colds, can prevent the flu virus from infecting airways by jumpstarting the body's antiviral defenses.
The airborne transmission of the coronavirus SARS-CoV-2 via aerosol particles in indoor environment seems to be strongly influenced by relative humidity. This is the conclusion drawn by researchers from the Leibniz Institute for Tropospheric Research (TROPOS) in Leipzig and the CSIR National Physical Laboratory in New Delhi from the analysis of 10 most relevant international studies on the…
The SARS CoV-2 virus which causes COVID-19 may have been named prematurely. As more has become known about the infection, the severe disease does not appear to be a respiratory syndrome at all. Patients who only have a respiratory illness tend not to have a severe condition, while patients who develop a severe condition tend to have non-respiratory conditions, primarily thrombotic or hyper-immune…
Airborne and potentially deadly, the virus that causes COVID-19 can only be studied safely under high-level biosafety conditions. Scientists handling the infectious virus must wear full-body biohazard suits with pressurized respirators, and work inside laboratories with multiple containment levels and specialized ventilation systems. While necessary to protect laboratory workers, these safety…

Four researchers from the University of Amsterdam – a clinical microbiologist, an anthropologist, a social scientist and a health lawyer – explain…
The novel coronavirus that recently originated in Wuhan, China has grabbed headlines and caused concern among public health officials around the world. Two infectious disease experts share their insights on the novel coronavirus epidemic.
Influenza viruses cause substantial health hazards and claim many lives worldwide each year. Vaccines can keep the virus in check, however, they only protect against influenza when they match the circulating strains – which vary every season. But now, a reasearch team may have found a way to generate a universal vaccine. Led by researchers at the Icahn School of Medicine at Mount Sinai, the…
Healthcare is going digital worldwide at an incredibly rapid pace. More and more applications for prevention, diagnostics and therapy are being made into apps (with matching hardware) for smartphones and tablets or are even available as wearables for direct use on the body. Digitalisation is also striding forward in Germany, where doctors, therapists and patients still take a fairly analogue…
It appears that an influenza vaccine does not just work when it comes to influenza. A new study shows that elderly people who have been admitted to an intensive care units have less risk of dying and of suffering a blood clot or bleeding in the brain if they have been vaccinated. And this is despite the fact that they are typically older, have more chronic diseases and take more medicine then…
A team of researchers from the SingHealth Duke-NUS Academic Medicine Centre’s Viral Research and Experimental Medicine Centre (ViREMiCS) found that immune cells undergoing stress and an altered metabolism are the reasons why some individuals become sick from viral infections while others do not, when exposed to the same virus. The findings, published in medical journal Nature Medicine, have…
With a case fatality rate of 35 percent, a Middle East respiratory syndrome-related coronavirus (MERS-CoV) infection – also called camel flu – is a dangerous disease. About seven years ago, when the virus was first isolated, mortality was close to 100 percent since only severe infections that led to the patient being in intensive care were recorded. Today the environment of each victim is…
A genetic mutation that a Chinese scientist attempted to create in twin babies born last year, ostensibly to help them fend off HIV infection, is also associated with a 21% increase in mortality in later life, according to an analysis by scientists from UC Berkeley. The researchers scanned more than 400,000 genomes and associated health records contained in a British database, UK Biobank, and…
Scientists from Imperial College London and the University of Edinburgh have used gene-editing techniques to stop the bird flu virus from spreading, in chicken cells grown in the lab.
Sixty-two percent of Germans fear antibiotic resistance, according to a survey recently conducted by the German Federal Institute for Risk Assessment. ‘Patients colonised by multi-resistant pathogens are particularly scared. But many of these fears are rooted in misunderstandings,’ explained Professor Mathias Pletz at the Congress for Infectious Diseases and Tropical Medicine (KIT).
In patients with kidney failure, influenza-like illness (ILI) likely contributes to more than 1,000 deaths per year. The finding, which comes from a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN), points to the importance of protection against, surveillance of, and, where possible, treatment of such infections in patients with kidney dysfunction.…
Researchers at the University of Cambridge and the University of Oxford have discovered a new molecule that plays a key role in the immune response that is triggered by influenza infections.
In healthy individuals, the Zika virus causes flu-like symptoms. If a pregnant woman becomes infected, the unborn child can suffer from severe brain abnormalities as a result of mechanisms that have not yet been explained. A study by the Technical University of Munich (TUM) and the Max Planck Institute of Biochemistry (MPI-B) shows that Zika virus proteins bind to cellular proteins that are…
Partners who could hardly be further apart – yet have a lot in common – have united to fight resistant pathogens. The International Consortium for Anti-Infective Research (iCAIR) is based in Germany and Australia – separated by nearly 16,000 km as the crow flies. This has not stopped the research cooperation from achieving its objectives: the development of new agents against infections.
This year’s unexpectedly aggressive flu season reminds everyone that although the flu vaccine can reduce the number of people who contract the virus, it is still not 100 percent effective. Researchers report that a tweak to a small-molecule drug shows promise for future production of new antiviral therapies that could help patients, regardless of the strain with which they are infected. The…
Scientists at Columbia University’s Mailman School of Public Health developed a system to accurately predict the geographic spread of seasonal influenza in the United States up to six weeks ahead of time.
Nurses have a distinctive and crucial role in the development and implementation of sound health policy,’ according to Annette Kennedy, President of the International Council of Nurses, which represents 135 National Nurses Associations and around 17 million nurses worldwide.
For many of us, a flu shot is a fall routine. Roll up a sleeve, take a needle to the upper arm and hope this year’s vaccine matches whichever viruses circulate through the winter. The most common method to make that vaccine is now more than 70 years old. It requires growing viruses in special, pathogen-free chicken eggs. It’s not a quick and easy manufacturing process. And, at best, it…
Each year, public health officials monitor the spread of influenza to identify which flu strains need to go into that year’s vaccines and where outbreaks will occur. But it can be difficult to predict how bad a particular flu season will be until people actually start getting sick. A new flu forecasting tool built by scientists at the University of Chicago aims to make better predictions by…
Over recent years, virology, once medicine‘s step-child, moved into the limelight, pushed by impressive progress and pulled by globalisation-induced need for expertise in virus diagnostics and viral epidemics.
Summer colds might seem rare, but people are actually just as likely to catch one in the summer as in the winter.
Scientists from St. Jude Children’s Research Hospital and Fred Hutchinson Cancer Research Center have developed an algorithm that functions like a Rosetta Stone to help decipher how the immune system recognizes and binds antigens. The research should aid development of more personalized cancer immunotherapy and advance diagnosis and treatment of infectious diseases.
Virology is fast emerging as a key discipline within modern healthcare against a backdrop of a shifting global demographic and the impact of climate change.
Researchers have discovered that secondary infection with the Methicillin-resistant Staphylococcus aureus (MRSA) bacterium (or “superbug”) often kills influenza patients because the flu virus alters the antibacterial response of white blood cells, causing them to damage the patients’ lungs instead of destroying the bacterium. The study suggests that inhibiting this response may help treat…
IBM scientists have developed a new lab-on-a-chip technology that can, for the first time, separate biological particles at the nanoscale and could enable physicians to detect diseases such as cancer before symptoms appear.
Researchers at Duke Health are fine-tuning a test that can determine whether a respiratory illness is caused by infection from a virus or bacteria so that antibiotics can be more precisely prescribed.
As the World Health Organization (WHO) ramps up its fight against antibiotic resistance, a new multi-country survey shows people are confused about this major threat to public health and do not understand how to prevent it from growing.
A banana a day may not keep the doctor away, but a substance originally found in bananas and carefully edited by scientists could someday fight off a wide range of viruses, new research suggests. And the process used to create the virus-fighting form may help scientists develop even more drugs, by harnessing the “sugar code” that our cells use to communicate. That code gets hijacked by…
Half a million square feet. More than 350 beds. And tomorrow, they clean it all over again. Every day, Environmental Services (EVS) staff members work to disinfect every surface in Children’s Hospital Los Angeles, playing a crucial behind-the-scenes role in preventing infections and keeping patients safe. Now, on top of scrubbing, spraying, mopping and wiping, they can add another action –…
It’s a race against the clock; every hour counts in efforts to halt the spread of a disease, but identifying anyone with whom the infected patient has had contact is time-consuming, with Contact Officers generally collecting data on paper. Now, however, scientists from the Nigerian Field Epidemiology Laboratory & Training Programme, the Helmholtz Centre for Infection Research, the Hasso…

Although receding since late March, the 2012-13 seasonal flu epidemic in metropolitan France, appears to be the longest in some 30 years, even if it did not strike the highest numbers, according to the monitoring network Sentinelles-Inserm.
Dutch virologist Ron Fouchier and his colleagues around the world stopped their research into the bird flu virus H5N1 for a whole year to allow an international debate surrounding the benefits and risks of their work.
When country doctor Edward Jenner inoculated 8-year-old James Phipps with pus from a cowpox lesion on a milkmaid’s hand, little did he know that he had started a long lasting revolution in preventive medicine.
If the hopes of inventors are to be believed, in around 20 years’ time there will be ‘real artificial lungs -- for now the endpoint of a history that began 84 years ago with the invention of the iron lung. Until then, non-invasive and invasive mechanical respiration will continue to dominate the hospital, complemented by extracorporeal procedures for blood oxygenation and decarbonisation,…
As concern over the potential mutation of the latest form of influenza virus continues to vex governments and their healthcare organisations, WHO 2009 data has shown that acute respiratory infections, influenza and respiratory syncitial virus (RSV) epidemics coincide with epidemics of S. pneumoniae. In fact, half or more of flu-associated mortality in the 1918-1919 Spanish Flu epidemic is…
The European Scientific Conference on Applied Infectious Disease Epidemiology (ESCAIDE) aims to strengthen and expand the network of specialists, share scientific knowledge and experience internationally, and provide a dedicated platform for EPIET/FETP (field epidemiology training programme) fellows to present their work.
The threat of communicable diseases will become even worse in the near future. At the European Health Forum Gastein, the European Union's leading health policy congress for experts and decision-makers, experts stressed that there are a number of risk factors which contribute to a growing risk of the spread of communicable diseases into Europe, namely into the European Union.
Experts predict that 25-50% of the French population could be affected by the H1N1 flu this autumn. According to Patrick Berche, head of the microbiology department at the Necker Hospital in Paris, the likely second wave of the epidemic would produce a great number of cases due to the highly contagious nature of the virus.
During the race to produce vaccines against evolving influenza viruses the slowness of their manufacture has turned producers more sharply towards cell culture technology. Using the traditional process, fertilised chicken eggs must first be inoculated with live flu virus, then the resulting egg-adapted virus must be purified and inactivated to produce trivalent inactivated virus (TIV), during…
Swine flu has been confirmed in a number of countries and it is spreading from human to human, which could lead to what is referred to as a pandemic flu outbreak. Pandemic flu is different from ordinary flu because it's a new flu virus that appears in humans and spreads very quickly from person to person worldwide. On Wednesday, the World Health Organization raised the pandemic threat Level to 5…
The machine 'qViro' which is the size of a coffee grinder will make virus counting much cheaper than traditional virus counting technology. The revolutionary new invention offers the potential to quickly muster and count the number of viruses in a sample in minutes - it is a portable, desktop instrument, powered from the USB drive of a computer - current competitors are the size of washing…
The next flu season will come. To prevent high-risk people from infections, the National Institute for Health and Clinical Excellence (NICE) recently published a final guidance on the use of the drugs oseltamivir, amantadine and zanamivir for the prophylaxis of influenza. "But vaccination is the main way to prevent flu", says Gillian Leng, NICE Deputy Chief Executive.
The next pandemia will come - rather sooner than later. The respiratory protection of frontline staff is a major part of healthcare facilities' preparation. To assist hospitals, ECRI Institute and the International Association of Healthcare Safety and Security present the web conference "Respiratory Protection: Preparing for Pandemic Flu" on July 17, 2008.
Do you remember your mother saying “cover your mouth when you cough”? Probably you do, because this exhortation accompanies the whole childhood. Maybe it is a kind of protest then, that in adulthood this simple rule is not followed by many. The British Department of Health now started a new campaign “Coughs and Sneezes spread Diseases” and calls for a better cold behaviour.
AIDS, SARS and now H5NI; just a brief beginning or the end? As the virus moves towards Europe, and millions of birds are slaughtered, interest has risen in a Chinese herb, a patent-sharing controversy and drug stockpiling
Czech Republic - The US firm Baxter International Inc. is to establish a production facility to produce a quite unique vaccine in CR.
