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.
Medivir AB, the emerging research-based specialty pharmaceutical company focused on infectious diseases, announces today that it has signed a collaboration agreement with Janssen Pharmaceutica N.V. for the discovery and development of drugs for the prophylaxis and treatment of dengue virus infection.
India could soon become a site for clinical trials to evaluate the effectiveness of a dengue vaccine, the Times of India reports. According to the drug controller general of India, vaccine maker Sanofi Pasteur recently submitted a proposal to test the vaccine to the country.
The International Vaccine Institute today announced the launch of the Dengue Vaccine Initiative, in collaboration with the Sabin Vaccine Institute, the Johns Hopkins University, and the World Health Organization, to support development of vaccines to control dengue fever, a widespread and expanding hemorrhagic fever that is endemic in most tropical and subtropical regions of the world.
Dengue illness, the most common mosquito-borne viral disease in the world, has expanded from its Southeast Asian origins and is resurgent in countries such as Argentina, Chile and the continental United States.
Ebola, a virus that causes deadly hemorrhagic fever in humans, has no known cure or vaccine. But a new study by University of Illinois at Chicago scientists has uncovered a family of small molecules which appear to bind to the virus's outer protein coat and may inhibit its entry into human cells.
Using chemical compounds found in a Japanese plant as a lead and the clever application of ultraviolet light, a Scripps Research Institute team has created a unique library of dozens of synthetic compounds to test for biomedical potential. Already, one of the compounds has shown great promise in inhibiting replication of HIV particles and fighting inflammation.
Guidance about pre-travel precautions and preventive measures are highlighted in the December 1, 2010 issue of Clinical Infectious Diseases, written by clinicians and researchers at the Uniformed Services University of the Health Sciences and their partners from the University of Texas Health Sciences Center, Naval Medical Research Center and others.
Boston University researchers have developed a simple diagnostic tool that can quickly identify dangerous viruses like Ebola and Marburg. The biosensor, which is the size of a quarter and can detect viruses in a blood sample, could be used in developing nations, airports and other places where natural or man-made outbreaks could erupt.
Scientists at Emory University and the University of St. Andrews have solved the structure of a key protein from Lassa virus, which is endemic to West Africa and can cause a deadly hemorrhagic fever.
NPR's Shots blog examines progress in the search for a vaccine to protect against the dengue virus. WHO estimates that 2.5 billion people worldwide are at risk of getting dengue, and most of them are in Asia and Latin America, the blog writes.
Sanofi Pasteur, the vaccines division of sanofi-aventis Group (EURONEXT: SAN and NYSE: SNY), announced today that its dengue vaccine is in final stage of clinical development. Sanofi Pasteur's dengue vaccine, the world's most clinically advanced dengue vaccine candidate, entered its first phase 3 clinical study in Australia.
Paragon Bioservices, a Baltimore-based CMO focused on the contract research, process development and manufacturing of biologics, announced today that it has been awarded a $4.99 million contract to assist the U.S. Army Medical Research Institute for Infectious Diseases in its vaccine development efforts.
NanoViricides, Inc. reports that it has filed its financial year end annual report (Form 10K) with the Securities and Exchange Commission (SEC) yesterday in a timely manner.
Inviragen and PharmaJet announced the award of a five year, $15.5 million dollar contract from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, to advance the development of a needle-free, easy to administer dengue vaccine. The award will fund preclinical studies, regulatory filings, manufacturing and clinical testing of Inviragen's tetravalent dengue vaccine, DENVax delivered with PharmaJet's convenient needle-free injection device.
Australians researchers are moving towards producing the first ever vaccine for dengue fever, the potentially life-threatening infection spread by mosquitoes in the tropics. At present late stage clinical trials are underway for a vaccine that would protect against all four known strains of the disease. Participants are now being recruited in Perth, Adelaide and Brisbane.
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.
