Researchers hope to spur investment in control strategies 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. The economic burden of dengue (pronounced DENgee) in the Western Hemisphere, according to a new study from Brandeis University researchers published today in the American Journal of Tropical Medicine and Hygiene, is...

There is a new player in the fight against dengue fever in Malaysia, 6,000 of them actually. Malaysia released about 6,000 genetically modified mosquitoes into a forest in the first experiment of its kind in Asia aimed at curbing dengue fever, officials said Wednesday to AP. The field test is meant to pave the way for the use of genetically engineered Aedes aegypti male mosquitoes to mate with females and produce no offspring or ones with shorter lives, hopefully curtailing the mosquito...

An official said on Tuesday that Malaysia has delayed a landmark field trial to release genetically modified mosquitoes designed to combat dengue fever. The 4,000 to 6,000 male Aedes aegypti mosquitoes were originally scheduled to be released last month in an attempt to fight dengue, which killed at least 134 people last year in Malaysia alone. The insects have been engineered so that their offspring quickly die, curbing the growth of the population in a technique researchers hope could...

British scientists have created genetically modified sterile mosquitoes in an experiment to kill off others in their species, and researchers are hopeful that early field trials could help to stave off the rapid spread of dengue fever. This is the first time genetically altered mosquitoes have been set loose in the wild, after years of lab experiments and calculations. But while scientists believe the trial could lead to a breakthrough in halting the disease, critics argue that mutant...

An estimated 5 percent of the Key West, Fla., population "“ over 1,000 people "“ showed evidence of recent exposure to dengue virus in 2009, according to a report from the Centers for Disease Control and Prevention (CDC) and the Florida Department of Health. After three initial locally acquired cases of dengue were reported in 2009, scientists from the CDC and the Florida Department of Health conducted a study to estimate the potential exposure of the Key West population to dengue...

Some of the human immune system's defenses against the virus that causes dengue fever actually help the virus to infect more cells, according to new research published May 6 in the journal Science. The researchers behind the work, from Imperial College London, hope their new findings could help with the design of a vaccine against the dengue virus. The study also brings scientists closer to understanding why people who contract dengue fever more than once usually experience more severe and...

SEOUL, March 9, 2010 /PRNewswire/ -- PDVI (Pediatric Dengue Vaccine Initiative), a program of the International Vaccine Institute (IVI) 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. Breaking news articles from reliable sources are displayed on a world map according to the location of dengue outbreaks. Dengue fever is endemic in over 100 countries and puts at risk half...

High temperatures, humidity and low wind speed are associated with high occurrence of dengue fever according to a study published in the open access journal BMC Public Health. Dengue fever is a viral disease transmitted by mosquitoes in tropical and subtropical regions of the world. It is one of the most significant insect-borne diseases found in humans, with 2.5 billion people living in high-risk areas globally. In recent years, the number of cases occurring has increased dramatically. Being...

Experts say more than half of the states in the U.S. now have mosquitoes that are known to spread dengue fever. A new report by the Natural Resources Defense Council showed that two types of mosquitoes capable of transmitting the dengue fever virus are invading Southern and Mid-Atlantic states, creating conditions more favorable for an outbreak. An estimated 173 million Americans live in counties that now contain one or both of the mosquito species, a problem that could escalate with global...

U.S. and Costa Rican scientists say they've developed the first climate-based computer model that can predict dengue fever outbreaks in Costa Rica. An interdisciplinary team of researchers from the University of Miami and the University of Costa Rica said the new model can predict dengue fever epidemics with 83 percent accuracy, up to 40 weeks in advance of an outbreak and provide information on the magnitude of future epidemics. The Costa Rican model, the researchers said, can be expanded to...
