Arbovirus is the name given to Arthropod-borne viruses, that is, viruses that are transmitted to vertebrates, such as people and mammals, by blood-feeding insects called arthropods, such as mosquitoes. Vertebrate infection occurs when the infected insect bites an animal or person and takes a blood meal.
Researchers investigated the potential exposure of peri-urban non-human primates (NHPs) residing near Yangon to arboviruses that have raised health concerns.
Colorado State University researchers are part of a $12.5 million National Science Foundation-supported institute that will advance research and education around viral emergence – the process of viruses jumping from animals to humans.
A new study looks at the immunomodulatory effects of mosquito bites, using Aedes aegypti as the model species and humans as the host.
A potential new approach to administering an existing Japanese encephalitis (JE) vaccine could make it more affordable and increase dose numbers in Australia.
INTEGRA Biosciences’ ASSIST PLUS pipetting robot is helping the Arbovirus Testing Lab at the New Hampshire Public Health Laboratories in Concord, USA, to streamline sample pooling for West Nile and Eastern equine encephalitis virus testing.
To address this gap in research regarding the understanding of post-replicative alphavirus RNPs, scientists have created a novel proteome-wide approach known as viral RNA interactome capture (vRIC). This study is available in the bioRxiv* preprint server while awaiting peer review.
Yellow fever was the first human disease to have a licensed vaccine and has long been considered important to an understanding of how epidemics happen and should be combated.
A new variant of the virus that causes COVID-19, identified in Brazil, is likely more transmissible than its parent strain because of mutations in the spike protein, according to researchers.
An interesting study published on the preprint server medRxiv in November 2020, dealing not with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that is the cause of the COVID-19 pandemic, but with the publications that have appeared as a consequence of the outbreak, comparing them with the similar trove of publications that followed the Zika virus outbreak in 2016.
A new study describes two promising small molecules that inhibit a host cell factor, called nucleotide binding oligomerization domain-containing protein 2 (NOD2), that inhibits the replication and spread of many arboviruses. This could lead to the development of broad-spectrum antivirals. The study's findings have been published on the preprint server bioRxiv*.
Yellow fever virus is normally confined to the Amazon region, but the virus circulated in the Southeast of Brazil between 2016 and 2018, causing the worst epidemic and epizootic outbreaks there for decades.
A study conducted by an international team of researchers with FAPESP's support shows that infection by chikungunya virus can produce even more severe manifestations than the typical symptoms of the disease, such as acute fever, headache, rash, and intense joint and muscle pain.
A multidisciplinary team from The University of Texas Medical Branch at Galveston has uncovered a Zika virus mutation that may be responsible for the explosive viral transmission in 2015/2016 and for the cause of microcephaly (babies with small heads) born to infected pregnant women.
The life span of the Aedes aegypti mosquito ranges from two to four weeks depending on environmental conditions, during which the female lays about one thousand eggs in water-filled containers close to human environments, because it needs human blood in order to reproduce and to complete its life cycle.
As the COVID-19 pandemic continues with many thousands of new infections reported each day, there is a need for widely applicable surveillance testing to gain a better understanding of infection rates, especially the number of infections in people with mild or no symptoms, who can still be carriers.
Although eastern equine encephalitis (EEE), a mosquito-borne illness, has existed for centuries, 2019 has been a particularly deadly year for the disease in the United States.
The World Health Organization has made it a goal to eliminate human rabies deaths due to dog bites by the year 2030. An increase in dog rabies vaccination rates decreases dog rabies cases, human exposure, and human deaths, researchers now report in PLOS Neglected Tropical Diseases.
Health officials have announced over the weekend that more people have been infected with or died from the EEE virus, making 2019 the worst year yet for recorded cases.
Even as the Zika virus raged in Brazil, clinicians observed a curious phenomenon: all babies born to mothers infected with the virus during pregnancy were not affected with the characteristic birth anomalies caused by this infection.
An immune mechanism that makes babies more likely than adults to die from sepsis has been identified by scientists affiliated with the Center for Research on Inflammatory Diseases in Ribeirão Preto, São Paulo State (Brazil).
