These viruses, which mostly circulate in the tropics, cause large outbreaks of…
Scientists have found that organoids (tiny tissue cultures made from human cells that simulate whole organs) known as “mini-brains” can be infected by the SARS-CoV-2 virus that causes COVID-19.
More than one in four of the most viewed COVID-19 videos on YouTube in spoken English contains misleading or inaccurate information, reveals the first study of its kind, published online in BMJ Global Health. Public health misinformation on COVID-19 is reaching far more people than in previous pandemics and has considerable potential for harm, warn the researchers. While good quality accurate…
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.
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…
The World Health Organisation's (WHO) Essential Medicines List and List of Essential Diagnostics are core guidance documents that help countries prioritize critical health products that should be widely available and affordable throughout health systems. Now, updated versions of the two lists have been published, focusing on cancer and other global health challenges, with an emphasis on effective…
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…
The safety of blood transfusions is questioned again and again by the mass media. Sometimes ‘bad’ blood causes infections; sometimes a transfusion leads to cancer years later. The fact is that transfer blood is subjected to the highest safety standards – there are very clear statutory regulations. Nonetheless, there will be shortages of ‘life’s fluid’ because, given increasing…
Researchers from the University of Bath are developing a new tool for detecting the presence of Dengue fever early on, helping prevent people from suffering potential life-threatening complications.
Test results are denoted by a colour change and could be further analysed by a smartphone app, making it attractive as a point-of-care diagnostic device.
Macrophages are immune cells that are supposed to protect the body from infection by viruses and bacteria. Yet Zika virus preferentially infects these cells. Researchers at University of California San Diego School of Medicine have now unraveled how the virus shuts down the genes that make macrophages function as immune cells.
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…

A Vanderbilt team took the next leap forward in using a little-known bacteria to stop the spread of deadly mosquito-borne viruses such as Zika and dengue. Wolbachia are bacteria that occur widely in insects and, once they do, inhibit certain pathogenic viruses the insects carry. The problem with using Wolbachia broadly to protect humans is that the bacteria do not normally occur in mosquitoes…
A powerful antiviral protein may act as a checkpoint for keeping or ending a pregnancy. When exposed to Zika virus before birth, mouse fetuses with the protein commit cell suicide, while fetuses without it continued to develop. The result, published in Science Immunology, suggests that the protein, a receptor involved in immune cell signaling, plays a role in spontaneous abortions and other human…
Donating blood is a tangible way to help people who are struggling with serious health conditions, yet many people may not think about it or make time for it. In January – which the American Red Cross has dubbed National Blood Donor Month – blood bank supplies are typically among the lowest of the year, as many people have been traveling or busy with the holidays. Inclement weather can also…

In Europe, the first baby with Zika-related microcephaly was born in July. The mother had contracted the Zika virus while travelling in America. How dangerous is the virus for Europeans, particularly since many visited Brazil for the Olympic Games in Rio?
A new study by Johns Hopkins researchers suggests that a specialized area of the mosquito brain mixes tastes with smells to create unique and preferred flavors. The findings advance the possibility, they say, of identifying a substance that makes “human flavor” repulsive to the malaria-bearing species of the mosquitoes, so instead of feasting on us, they keep the disease to themselves,…
Researchers have found that Zika virus can live in eyes and have identified genetic material from the virus in tears, according to a study from Washington University School of Medicine in St. Louis. The research, in mice, helps explain why some Zika patients develop eye disease, including a condition known as uveitis that can lead to permanent vision loss.
There are a couple strains of herpes so common that researchers estimate 90% of the human population have them. These strains, human herpes 6 and human herpes 7, usually do not cause severe symptoms when people acquire them. But researchers know that under certain circumstances, dormant herpes viruses in the body can unexpectedly come roaring back and cause complications not typically associated…

Real-time data integration and analysis can help public health authorities to maximize efficacy of intervention strategies. Dr. Richard Neher from the Max Planck Institute for Developmental Biology, Germany and Dr. Trevor Bedford from the Fred…
As one of medicine’s largest challenges, viral infections often escape vaccines due to their natural ability to mutate rapidly and develop drug resistance easily. Many viruses, such as Zika, Ebola and dengue fever, have grown into major global health epidemics with great human and economic toll. IBM Research and Singapore’s Institute of Bioengineering, Nanotechnology (IBN) announced they have…
As scientists scramble to get a Zika virus vaccine into human trials by the end of the summer, a team of researchers is working on the first-ever vaccine to prevent another insect-borne disease – Leishmaniasis – from gaining a similar foothold in the Americas.
Studying a new type of pinhead-size, lab-grown brain made with technology first suggested by three high school students, Johns Hopkins researchers have confirmed a key way in which Zika virus causes microcephaly and other damage in fetal brains: by infecting specialized stem cells that build its outer layer, the cortex.
Before his presentation at ECCMID 2016, Dr Guillaume Béraud, Infectious Disease Specialist, in the Centre Hospitalier Universitaire de Poitiers, Poitiers, France, talked to European Hospital about the results from his modelling of these three “childhood” diseases measles, mumps and rubella.
Since the recent link to severe neurological defects in infants born to mothers infected during pregnancy, Zika virus (ZIKV) has become a public health and research priority. A study reports details from the 2015 Zika outbreak in Rio de Janeiro - the first with a high proportion of cases confirmed by molecular diagnosis - and proposes changes to the current diagnostic criteria for ZIKV disease.
The Zika virus may be associated with an autoimmune disorder that attacks the brain's myelin similar to multiple sclerosis, according to a small study that is being released today and will be presented at the American Academy of Neurology's 68th Annual Meeting in Vancouver, Canada, April 15 to 21, 2016.
The European Society of Clinical Microbiology and Infectious Disease (ESCMID) – an organization that explores risks, knowledge sharing and best practices in the fight against infectious disease – has received more than 300 late-breaker abstract submissions for its annual congress, ECCMID 2016 in Amsterdam.
From the beginning the accusation somehow beggared belief. A ‘mild’ virus was blamed for causing hideous malformations in babies’ heads. Brazil, a country suffering its worst recession since the 1930s, as well as political upheaval, became the focus of a worldwide healthcare scare.
Rapid testing for the Zika virus is a critical need in the recent Ebola-affected countries of Liberia, Sierra Leone and Guinea, says a Georgetown University professor, because of the recent Zika outbreak on nearby Cape Verde and the similarity in symptoms between Zika and early Ebola.
Humabs BioMed SA and the Institute for Research in Biomedicine (IRB) affiliated to the Università della Svizzera italiana announced the identification, isolation and characterization of two Ebola virus neutralizing monoclonal antibodies from the blood of a survivor of an Ebola infection.
The Zika virus, unlike other mosquito-borne viruses such as dengue, is relatively unknown and unstudied. That is set to change since Zika, now spreading through Latin America and the Caribbean, has been associated with an alarming rise in babies born in Brazil with abnormally small heads and brain defects – a condition called microcephaly.
Experts at the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) – an organization promoting research, risk assessment, knowledge sharing and best practices in the fight against infectious diseases – are developing tools to monitor the spread of the Zika virus and are conducting research to gather more solid data to better assess the risks associated with the…
