Researchers from Maryland and South Carolina have developed a novel four-component vaccine that protects monkeys against all four strains of dengue virus and may potentially offer protection to the millions of humans at risk worldwide. They report their findings in the July 2008 issue of the Journal of Virology.

A study by researchers in Thailand, Japan, and the UK has shown a negative correlation between dengue hemorrhagic fever (DHF) and the density of the Aedes mosquitoes that transmit the virus.

Brazil's military will help fight an outbreak of dengue fever in Rio de Janeiro, the defense ministry said at the weekend, after the disease killed 49 people and made more than 30,000 ill this year.

A pair of researchers has answered a puzzle about why efforts to lower the transmission of dengue virus in Thailand have not resulted in decreases in the severe, life-threatening, form of the infection. In fact, it seems to have had just the opposite effect.

Researchers at the Novartis Institute for Tropical Diseases and the Genome Institute of Singapore have identified new host genes associated with dengue virus infection, which may open new avenues to developing a drug to treat the disease.

Dawn has not yet broken but already more than 1,000 sick children queue outside a hospital in Phnom Penh in a desperate wait to get treatment for dengue, a mosquito-borne disease taking a heavy toll on Cambodia's young.

Global warming is often in the news these days, usually in connection with changing, and sometimes destructive, weather patterns. But the World Health Organization says rising temperatures also have alarming implications for public health.

In an effort to halt the spread of deadly infectious diseases now threatening to reach epidemic proportions around the world, an unprecedented research effort was launched today by IBM, The University of Texas Medical Branch (UTMB), and the University of Chicago to discover drugs to treat and cure dengue fever, West Nile encephalitis, hepatitis C, and a host of related diseases including yellow fever.

This year South East Asia's monsoon has brought its usual flooding and intense humidity. But it has also brought with it an increase in dengue fever cases. Already thousands of people have died.

Like much of Southeast Asia, Cambodia is struggling with an epidemic of dengue fever, which has killed scores of children and is threatening to overwhelm the country's fragile health care system. Experts say that early monsoon rains and heavy migration are spreading the mosquito-borne virus, while some also blame the authorities for not acting quickly enough to control the outbreak.

Health experts at a conference in Kuala Lumpur say climate change is causing an increase in disease in Asia. They warn the situation is likely to get worse and urge governments to be prepared.

More than hundred children were killed by dengue fever this year in Cambodia and it is expected that the disease will spread when the rainy season peaks during the next few months, health officials said Friday.
