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.
At the first sign of a disease pandemic, public health officials should begin strongly communicating about the extent of the outbreak and the steps that can be taken by the public to avoid infection. That's the recommendation of two mathematical biologists who have modified the most widely used infectious disease transmission model to account for the impact of news media coverage.
Numerate, Inc. announced today that it has been awarded a new three-year contract by the Defense Threat Reduction Agency (DTRA), an agency within the U.S. Department of Defense, to adapt its pioneering small-molecule drug design platform to the rapid design and optimization of drugs against biowarfare agents.
New studies show that treatments targeting specific viral genes protected monkeys infected with deadly Ebola or Marburg viruses. Furthermore, the animals were protected even when therapeutics were administered one hour after exposure-suggesting the approach holds promise for treating accidental infections in laboratory or hospital settings.
After more than a decade of development at the National Institutes of Health, a vaccine to prevent infection by the mosquito-borne dengue virus has begun human clinical testing. The vaccine was developed by scientists at the National Institute of Allergy and Infectious Diseases (NIAID) and is undergoing clinical study at the Johns Hopkins Bloomberg School of Public Health in Baltimore.
Several cases of dengue fever, a potentially fatal viral disease transmitted by the bite of urban dwelling Aedes aegypti and Aedes albopictus mosquitoes, have recently been reported in the continental United States. Prevalent in Central America and the Caribbean, dengue fever's most common symptoms include fever, chills, headache, and body aches lasting several days. The disease's more threatening form, dengue hemorrhagic fever, can cause internal bleeding, loss of blood pressure, and death. Over the past five years, outbreaks of both forms of the disease have been reported in Texas and Florida.
NanoViricides, Inc. reports that the results of the evaluation of several of its nanoviricides anti-Ebola agents were presented July 17th at the Annual Meeting of the American Society for Virology, July 17-21, at Montana State University, Bozeman, MT. Dr. Corinne Scully delivered the presentation, which was entitled "Polymeric Micelle Nanomaterials as Antiviral Compounds For Ebola Virus Infection."
Blood samples taken from one of the suspected cases in Sangha Region, Republic of Congo, tested negative for several viral haemorrhagic fevers (Ebola, Marburg, CCHF, Arenavirus).
For someone with a severe, incurable lung disorder such as cystic fibrosis or chronic obstructive pulmonary disease, a lung transplant may be the only chance for survival. Unfortunately, it's often not a very good chance. Matching donor lungs are rare, and many would-be recipients die waiting for the transplants that could save their lives.
NanoViricides, Inc. reports that its anti-Dengue drug candidates demonstrated significant protection in the initial animal survival studies of Dengue virus infection. The studies were performed in the laboratory of Dr. Eva Harris, Professor of Infectious Diseases at the University of California, Berkeley.
An experimental vaccine developed to prevent outbreaks of Marburg hemorrhagic fever continues to show promise in monkeys as an emergency treatment for accidental exposures to the virus that causes the disease. There is no licensed treatment for Marburg infection, which has a high fatality rate.
NanoViricides, Inc. reports that its anti-Dengue drug candidates demonstrated significant efficacy in the recently completed preliminary cell culture studies. The studies were performed in the laboratory of Dr. Eva Harris, Professor of Infectious Diseases at the University of California, Berkeley.
Scientists using tiny particles of genetic material to interfere in the replication process of the deadly Ebola virus have successfully prevented monkeys exposed to that virus from dying of hemorrhagic fever. The proof-of-concept study, published in this week's issue of The Lancet, suggests that such protection also should be possible in humans.
Sponsored by the National Institutes of Health, Saint Louis University's Center for Vaccine Development is conducting research of an investigational vaccine designed to prevent people from contracting dengue, a potentially lethal virus that has rapidly spread around the world.
Inviragen has announced the initiation of the first clinical trial of its vaccine to protect against dengue fever. The trial, to be conducted at Saint Louis University, is designed to assess the safety of Inviragen's investigational dengue vaccine.
Some of the human immune system's defences against the virus that causes dengue fever actually help the virus to infect more cells, according to new research published today in the journal Science.
Peregrine Pharmaceuticals, Inc. today announced the publication of data showing phosphatidylserine -targeting antibodies can block one of the key ways the AIDS virus gains entry into certain blood cells. The data were generated by scientists at Duke University as part of their ongoing AIDS vaccine research.
Peregrine Pharmaceuticals, Inc. today announced the publication of data showing phosphatidylserine (PS)-targeting antibodies can block one of the key ways the AIDS virus gains entry into certain blood cells. The data were generated by scientists at Duke University as part of their ongoing AIDS vaccine research. The article titled "Anti-Phospholipid Human Monoclonal Antibodies Inhibit CCR5-Tropic HIV-1 and Induces β-Chemokines" is available online today and will be published in the April 12, 2010 edition of the Journal of Experimental Medicine.
New World hemorrhagic fevers are emerging infectious diseases found in South America that can cause terrible, Ebola-like symptoms. Current treatments are expensive and only partially effective.
PDVI, a program of the International Vaccine Institute funded by the Bill & Melinda Gates Foundation, announces today the launch of http://www.denguewatch.org, a news hub for tracking dengue fever epidemics worldwide.
A new study led by St. Jude Children's Research Hospital investigators disproves reports that well-fed children are more vulnerable to the dengue virus. Mosquitoes spread the virus, which can cause severe flu-like symptoms and sometimes lethal complications.
