Viral hemorrhagic fevers (VHFs) refer to a group of illnesses that are caused by several distinct families of viruses. In general, the term "viral hemorrhagic fever" is used to describe a severe multisystem syndrome (multisystem in that multiple organ systems in the body are affected). Characteristically, the overall vascular system is damaged, and the body's ability to regulate itself is impaired. These symptoms are often accompanied by hemorrhage (bleeding); however, the bleeding is itself rarely life-threatening. While some types of hemorrhagic fever viruses can cause relatively mild illnesses, many of these viruses cause severe, life-threatening disease.
New research out of the University of Texas Medical Branch potentially points to an effective treatment for Lassa fever, a dangerous, often fatal disease common to much of West Africa but considered a major threat to global health.
Research paper provides pathogen incidences for potential bioterrorism agents in the Netherlands from 2009 to 2019. The study highlights the need for biosecurity measures based on the observed incidences.
Researchers presented a stochastic model of yellow fever transmission.
Researchers isolated a novel virus of the Orthonairovirus genus.
Discovery of a novel arterivirus in Amazonian rodents sheds light on viral communities and raises concerns about potential transmission to humans.
Unsterilized laboratory wastewater from the U.S. Army Medical Research Institute of Infectious Diseases at Fort Detrick, Maryland, spewed out the top of a rusty 50,000-gallon outdoor holding tank, the pressure catapulting it over the short concrete wall that was supposed to contain hazardous spills.
In a recent study published in the journal Emerging Infectious Diseases, researchers analyzed ticks that bit humans between January 2014 and March 2021 in France for the presence of bacterial pathogens.
For mosquito-borne diseases such as dengue fever, the abundance of the insects in places where people gather has long served as the main barometer for infection risk.
Scientists from the United States have conducted a systematic review to understand whether cattle increase the risk of contracting vector-borne diseases by humans. The review is currently available on the medRxiv* preprint server.
Researchers briefly outlined how viral infections trigger endocrinopathies in humans.
In a new study, researchers examined how the innate immune system detects filoviruses.
Researchers reported the detection of arenavirus RNA from various species of bats sampled between 2007 and 2011 from Brazil.
For the first time, scientists have detected monkeypox virus in the testes of macaques during the acute phase of infection, according to research published online today in the journal Nature Microbiology.
In a recent study, researchers determined if monkeypox (MPX) infection affected the hemostatic system like that observed in coronavirus disease 2019 (COVID-19).
An obscure family of viruses, already endemic in wild African primates and known to cause fatal Ebola-like symptoms in some monkeys, is "poised for spillover" to humans, according to new University of Colorado Boulder research published online Sept. 30 in the journal Cell.
In the study, which appeared on September 27 in Nature Communications, scientists analyzed decades of environmental data associated with Lassa virus outbreaks, revealing temperature, rainfall and the presence of pastureland areas as key factors contributing to viral transmission.
Researchers described the Marburg virus (MARV) July 2022 outbreak in Ghana and efforts globally to curtail MARV transmission.
A modified tuberculosis (TB) vaccine developed at Texas Biomed could help treat a form of bladder cancer, called non-muscle invasive bladder cancer, without strong side effects.
Ghana announced the country’s first Marburg virus disease outbreak, after receiving a confirmatory report of the disease from the World Health Organization’s (WHO) Collaborating Centre Laboratory.
Researchers at the University of Texas Medical Branch have achieved success with a new vaccine developed to fight Lassa Virus, a pathogen that causes Lassa fever.
