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.
Scientists studying animal viruses with the potential to infect humans have discovered a critical protein that could facilitate the spread of a family of organisms known as arteriviruses.
EMBL's European Bioinformatics Institute (EMBL-EBI) has launched the Pathogens Portal – an online platform that enables researchers, clinicians, and policymakers to access the most comprehensive collection of biomolecular data about pathogens.
The majority of what scientists know about viruses in animals comes from the list of nucleotides that constitute their genomic sequence, which, although useful, provides relatively few signals about a virus’ propensity to infect people.
The Crimean Congo Hemorrhagic Fever Virus can be prevented by therapeutically relevant human monoclonal antibodies, according to research led by the University of California, Riverside.
Briefly blocking a key molecule when administering the only approved vaccine for tuberculosis vastly improves long-term protection against the devastating disease in mice, researchers from Texas Biomedical Research Institute report this week in the Journal of Immunology.
Scientists from the Karolinska Institutet discovered certain metabolic mechanisms that SARS-CoV-2 employs to attack lung tissue.
Rift Valley fever virus causes economically devastating outbreaks of hemorrhagic fever in livestock such as sheep, goats and cattle. These mosquito-borne outbreaks lead to infection in people working with dead or dying animals, sometimes causing hundreds of human cases and dozens of deaths.
