Environmental changes may reduce the diversity of mosquitos, but bring about a greater abundance of viruses, scientists from Charité in Berlin in cooperation with Leibniz-IZW find.
Are climate change and air pollution making neurologic diseases like headaches, dementia and multiple sclerosis (MS) worse? A scoping review of research explores the connection.
A comprehensive assessment of scientific literature has uncovered empirical evidence that more than 58% of human diseases caused by pathogens, such as dengue, hepatitis, pneumonia, malaria, Zika, have been aggravated by climatic hazards.
Over the last 50 years, malaria parasites have developed resistance to seven drugs, but a new way to identify future antimalarials holds promise.
COVID-19 measures such as school closures and ‘high-traffic and mixing’ areas had the strongest association, providing clues for new intervention approaches.
In both the mice and organoids, cytokines suppressed tumor growth after treatment, and defense cells migrated to the brain region affected by the tumor, alerting the immune system to its existence.
Researchers have developed a diagnostic for SARS-CoV-2 that is capable of differentiating between COVID-19 and the garden-variety bug with fast turnaround.
Artificial intelligence (AI) could match the impact of PACS on radiology. Covid-19 stimulated the development and testing of AI diagnostic-aiding tools in radiology, an unintended consequence of the pandemic. More image data sets have been created to train AI software – an unexpected benefit for radiology research.
In a preclinical study, NIH scientists found that the commonly used antibiotic methacycline may be effective at combating the neurological problems caused by Zika virus infections.
A deadly combination of two mosquito-borne viruses may be a trigger for stroke, new research published in the The Lancet Neurology has found. University of Liverpool researchers and Brazilian collaborators have been investigating the link between neurological disease and infection with the viruses Zika and chikungunya. These viruses, which mostly circulate in the tropics, cause large outbreaks of…
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…
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.
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…
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.
Rising temperatures due to global warming are creating a permanent habitat in Europe for mosquitos from Asia. The Asian tiger mosquito (Aedes albopictus), or Aedes japonicas, are important vectors for the transmission of pathogens previously only found in tropical regions, like dengue fever, West Nile fever and the Chikungunya virus.
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…
The genome sequences of ape parasites related to Plasmodium vivax (P. vivax), the main source of mosquito-borne malaria outside Africa, provide insights on the origin and early evolution of the human parasite. This finding could have implications for better comprehending and eradicating malaria infection worldwide.
More than two years after reports of skyrocketing Zika rates surfaced worldwide, questions still loom about this complicated virus. Professor of Biological Science Hengli Tang and his postdoctoral researcher Jianshe Lang from the Florida State University take a deep dive into the differences between Zika and the Dengue virus.
Medicines given to household pets to kill fleas and ticks might be effective for preventing outbreaks of malaria, Zika fever and other dangerous insect-borne diseases that infect millions of people worldwide, according to a new study led by scientists at Calibr, a non-profit drug discovery institute closely affiliated with Scripps Research and TropIQ Health Sciences, a Dutch social enterprise.
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…
Combining a new compound with old drugs could provide an effective remedy against malaria and drug-resistant parasites.
Saliva is no way to pass a Zika virus infection. According to researchers at the University of Wisconsin–Madison who conducted studies with monkeys, casual contact like kissing or sharing a fork or spoon is not enough for the virus to move between hosts.
Summer colds might seem rare, but people are actually just as likely to catch one in the summer as in the winter.
The ‘Transmission, Prevention, and Reporting of Emerging Infectious Diseases’ program for the International Conference IMED 2016 in Vienna, this November, reflected events in the field of emerging diseases that have occurred over the last two years. Therefore, key congress topics included the Zika virus, the effects of global warming and the unusually high number of hospital-acquired…
ECR 2017 Guest Lecturer Maria de Fatima Vasco Aragao, a radiologist from Pernambuco state, Brazil, has been tracking the Zika virus ever since it broke out in her country in 2015. She will highlight how CT and MRI can help reach diagnosis, especially in the absence of microcephaly. In an exclusive interview with European Hospital correspondent Mélisande Rouger, the radiologist warned there might…
The ‘Transmission, Prevention, and Reporting of Emerging Infectious Diseases’ programme for the International Conference IMED 2016 in Vienna, this November, reflected events in the field of emerging diseases that have occurred over the last two years.
An analysis of 2,000-year-old human remains from several regions across the Italian peninsula has confirmed the presence of malaria during the Roman Empire, addressing a longstanding debate about its pervasiveness in this ancient civilization.
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.
Research by scientists in the US and UK has estimated that up to 1.65 million childbearing women in Central and South America could become infected by the Zika virus by the end of the first wave of the epidemic. Researchers from the WorldPop Project and Flowminder Foundation at the University of Southampton and colleagues from the University of Notre Dame and University of Oxford have also found…
Drexel University scientists have discovered an unusual mechanism for how two new antimalarial drugs operate: They give the parasite’s skin a boost in cholesterol, making it unable to traverse the narrow labyrinths of the human bloodstream. The drugs also seem to trick the parasite into reproducing prematurely.
The Zika epidemic has long assumed global proportions, experts told the Congress of the European Academy of Neurology in Copenhagen. Europe needs to get prepared to deal with the relentless spread of the health threat, in particular with a view to “imported” infection. Awareness for prevention and personal protection is important, in particular with thousands of athletes and fans soon…
The 13th Symposium of the European Academy of Dermatology and Venereology, which opened its doors last Thursday 19th May and took place in Athens, Greece, came to a conclusion yesterday, after more than 2,000 participants benefited from a series of scientific sessions focusing on the latest developments in Dermatology and Venereology.
The President of the World Federation of Neurology (WFN) Prof Raad Shakir (London), said today that following the first confirmed Zika-related case of microcephaly on US territory, in Puerto Rico, and the ever-growing number of sexually-transmitted Zika infections in Europe, “it is increasingly obvious that the Zika epidemic has long assumed global proportions.” As the opening of the Olympics…
Virologists from KU Leuven, Belgium, have shown that an experimental antiviral drug against hepatitis C slows down the development of Zika in mice. The research team was led by Professor Johan Neyts from the Laboratory of Virology and Chemotherapy.
In recent years, we have witnessed multiple epidemics of viral diseases such as Ebola or Zika. Rapid targeted intervention is key to containment. 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…
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.
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.
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…
As the largest group of health professionals in the world, and the first point of care for many, nurses are key to educating patients on prevention and risk of the Zika virus and providing care to those who need treatment.
Scientists uncover a port of liver entry for malaria parasites in a report published in The Journal of Experimental Medicine. If these results hold up in humans, drugs that target this entry protein might help prevent the spread of disease.
It’s travel time, bringing all the possibilities of fun – as well as disease risk. The dengue virus, eg, is endemic in 124 countries. It is carried and transmitted by mosquitoes. Typically, what follows is a non-fatal febrile illness characterised by fever, muscle pain, headache, and nausea and vomiting lasting 5-7 days.
Roche Applied Science and Google.org recently started a joint project to demonstrate the feasibility of developing a multidisciplinary surveillance, research and response system. This system will enhance the ability to predict and prevent emerging infectious diseases in East Africa. The East African region is known as one of the major hot beds for emergence of new infectious viral agents and new…
