Hemorrhagic Fever News and Research

RSS

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.

NIH funds new research to combat emerging viruses

Albert Einstein College of Medicine has received a five-year, $14 million per year grant from the National Institute of Allergy and Infectious Diseases (NIAID) to participate in a broad national effort to develop "plug-and-play" vaccines and antibody-based therapies against a wide range of emerging viruses. The grant is part of NIAID's new Research and Development of Vaccines and Monoclonal Antibodies for Pandemic Preparedness (ReVAMPP) Network, which was announced earlier today.

New research network focuses on high-priority viruses

The National Institutes of Health (NIH) has established a pandemic preparedness research network to conduct research on high-priority pathogens most likely to threaten human health with the goal of developing effective vaccines and monoclonal antibodies. Currently, many of the diseases caused by these pathogens have no available vaccines or therapeutics, and investing in this research is key to preparing for potential public health crises - both in the United States and around the world. NIH's National Institute of Allergy and Infectious Diseases (NIAID) expects to commit approximately $100 million per year to fund the program, pending the availability of funds.
