WHO Chief Adhanom Ghebreyesus has declared the novel coronavirus (SARS-CoV-2) a global health emergency. He said the decision was reached not because of the situation in China, but because of, “what is happening in other countries.” On Feb. 17, the number of infections totaled around 71,000 globally based on data of the WHO. COVID-19 – the official shorthand name of the novel corona virus…
Infrared thermometers are now used in most subway stations in China to prevent the spread of novel coronavirus (SARS-CoV-2) pneumonia (MCP). Many stations have implemented an artificial intelligence (AI) based fever screening system developed by the Beijing-based company Megvii Technology Limited. The system supports non-contact remote temperature screening from a distance of 3 meters. "This…
Research into the novel Wuhan seafood market pneumonia virus, the deadly "coronavirus" that has forced the Chinese government to quarantine more than 50 million people in the country's dense industrial heartland, will be facilitated by the UC Santa Cruz Genomics Institute. The Genomics Institute's Genome Browser team has posted the complete biomolecular code of the virus for researchers…
Scientists at the University of Bologna have conducted the largest analysis of coronavirus 2019-nCoV genomes sequenced so far. This analysis confirms that the virus originates in bats and shows a low variability: the virus heterogeneity is low. At the same time, researchers identified a hyper-variable genomic hotspot in the proteins of the virus responsible for the existence of two virus…
The situation is extraordinary: there have only ever been four declarations of public health emergencies of international concern in the past and now there are two at the same time. Whilst the risks associated with the novel coronavirus are still unclear, people in the Democratic Republic of the Congo are still battling with an outbreak of the deadly Ebola virus which has been ongoing since 2018…
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.
Scientists from The Peter Doherty Institute for Infection and Immunity in Melbourne have successfully grown the Wuhan coronavirus (also known as SARS-CoV-2) from a patient sample, which will provide expert international laboratories with crucial information to help combat the virus. This is the first time the virus has been grown in cell culture outside of China. The Royal Melbourne Hospital’s…
Nine people have died and more than 400 have been sickened by the new corona virus spreading in China. A few cases have been confirmed in Taiwan, Thailand, South Korea, Japan and the U.S., and on Wednesday, the World Health Organization is holding an emergency meeting on the outbreak. How worried about a new pandemic should we be? Virus researcher Ali Mirazimi, adjunct professor at the Department…
A new effective treatment of hepatitis C that was made available to all Danes last year, not only combats the virus, but is also effective against potentially fatal complications such as reduced liver functioning and cirrhosis. This is the result of a new study from Aarhus University and Aarhus University Hospital. Hepatitis C is a serious disease, but the biggest threat to someone’s health is…
Measles infections are not harmless – they can cause disease courses that may be of fatal outcome. Researchers of the Paul-Ehrlich-Institut (PEI) in co-operation with researchers from the UK and the Netherlands have now found out that measles viruses erase part of the immunological memory over several years. Affected persons are thus more susceptible to infections with other pathogens beyond…
It is an important step towards fighting one of the deadliest viruses known to man: The human medicines committee (CHMP) of the European Medicines Agency (EMA) has recommended granting a conditional marketing authorisation in the European Union for Ervebo (rVSVΔG-ZEBOV-GP), the first vaccine for active immunisation of individuals aged 18 years and older at risk of infection with the Ebola virus.…
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…
A little bit of norovirus – the highly infectious microbe that causes about 20 million cases of food poisoning in the United States each year – goes a long way. Just 10 particles of the virus can cause illness in humans. A team of University of Arizona researchers has created a simple, portable and inexpensive method for detecting extremely low levels of norovirus. Jeong-Yeol Yoon, a…
Globally, a trend of falling public trust in vaccines is alarming health officials and the World Health Organisation (WHO) lists vaccine hesitancy as one of the top 10 threats to global health. The UK’s Wellcome Trust 2018 Global Monitor – a survey of more than 140,000 people in over 140 countries – highlighted regions where confidence in vaccinations is lowest.
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 led by scientists at the U.S. Department of Energy (DOE) Joint Genome Institute (JGI) developed an algorithm that a computer could use to conduct a similar type of search in microbial and metagenomic databases. In this case, the machine “learned” to identify a certain type of bacterial viruses or phages called inoviruses, which are filamentous viruses with small, single-stranded DNA…
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…
A strain of the common cold virus has been found to potentially target, infect and destroy cancer cells in patients with bladder cancer. No trace of the cancer was found in one patient following treatment with the virus. The researchers published their findings in the medical journal Clinical Cancer Research. Researchers from the University of Surrey and Royal Surrey County Hospital investigated…
Sunburn and happy memories are not the only things we can bring home from a holiday. Sometimes parasites, fungi, viruses or bacteria from distant countries accompany our return, later to become noticeable in unpleasant ways, often to pose a real health threat. At the German Radiology Congress in Leipzig, Dr André Lollert and colleagues ventured into the world of tropical and travel medicine.
Vaccinating schoolboys against the potentially deadly human papillomavirus (HPV) could dramatically reduce head and neck cancers in men, according to research involving the University of Strathclyde. The two-year project studied 235 patients in Scotland with head and neck cancer and found that 78% of people with head and neck cancers were men, while HPV was present in 60% of the cancers. This…
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…
An international group of researchers has found that antibodies to the human papilloma virus type 16 (HPV16) develop in the body between six to 40 years prior to a clinical diagnosis of throat cancer, and their presence indicates a strong increased risk of the disease.
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.
A proof-of-principle study shows that gold nanoparticles loaded with CRISPR and other gene-editing tools safely and effectively edited blood stem cells.
In a new study, researchers from King’s College London have shown how skin vaccination can generate protective CD8 T-cells that are recruited to the genital tissues and could be used as a vaccination strategy for sexually transmitted infections (STIs), such as HIV or herpes simplex virus.
