New Malaria Antibody Drug Prevents Infection in Adults for 6 Months

A new malaria antibody treatment may keep more people free of the sometimes deadly disease for up to six months in regions where infection rates are high.

Instead of requiring the immune system to make enough antibodies, this experimental drug provides those who receive it with a large amount of lab-made antibodies. It requires an infusion via IV, but a shot version of the drug is in ear...

Scientists Engineer Mosquitoes That Can't Transmit Malaria

The fight against malaria could hinge on genetically engineered mosquitoes that have something called "gene drive."

Researchers from the Transmission: Zero team at Imperial College London report that they have engineered mosquitoes that slow the growth in their gut of the parasites that cause malaria. This delay would mean the mosquito would reach its natural life span before the parasite...

Monoclonal Antibody Might Help Prevent Malaria

Researchers are reporting early but encouraging findings on a potential new way to prevent malaria — an old foe that still ranks as a major killer worldwide.

In a small trial of healthy volunteers, U.S. government researchers found that a lab-engineered antibody protected most participants from infect...

New Malaria Treatment Gets First Approval for Use in Children

A new drug that can cure a certain type of malaria was approved in Australia Monday for kids and teens.

Global Warming Means Spread of Malaria, Dengue

Climate change could put billions more people at risk for deadly mosquito-borne diseases such as malaria and dengue, researchers said. They see the danger zone expanding within the United States, Europe and Asia.

If temperatures rise by about 3.7 degrees Celsius by the year 2100 compared to pre-industrial levels, 4.7 billion more people globally may be at risk for the diseases compared to...

From Cedar Trees and Grapefruit Rinds Comes a New Bug Repellent

Bugs beware: There's a powerful new insect repellent in town.

Just approved by the U.S. Environmental Protection Agency and known as nootkatone, the citrus-scented ingredient repels mosquitoes, ticks, bedbugs and fleas.

In high concentrations, it can kill these pesky insects and slow the spread of the diseases they can carry, according to the U.S. Centers for Disease Contro...

Lupus Drug Prevents Low Heartbeat in High-Risk Newborns: Study

A drug used to treat lupus and malaria -- hydroxychloroquine -- reduced by half the risk of a potentially fatal heart condition in newborns who were at high risk for it.

The condition -- known as congenital heart block (CHB) -- results in a dangerously low heart rate.

"Our study shows hydroxychloroquine as the first, safe, and highly effective drug for preventing pregnant wom...
