A malaria drug could help immune-compromised people who can't shake off babesiosis, a tick-borne parasitic infection, a new study says.

The drug tafenoquine helped cure four New England patients whose babesiosis infections weren't knocked out by the usual standard of care, researchers reported recently in the journal

  • There's been another case of locally acquired malaria in the United States, this time in Maryland, authorities report.

    It's the first time this has happened in that state in 40 years.

    No evidence connects this case to seven locally acquired infections in Florida or another one in Texas that were previously reported, according to the U.S. Centers for Disease Control and Prevention....

    The United States now has had eight reported cases of malaria, seven of them in Florida, state health officials reported Tuesday.

    Considered a public health emergency, these cases are the first in two decades to be acquired within this country's borders, not reported by someone who had traveled elsewhere, the U.S. Centers for Disease Control and Prevention

  • Public health authorities are continuing to investigate malaria cases in Florida and Texas, gathering mosquitoes for tests.

    Multiple mosquitoes from Sarasota County in Florida have tested positive for malaria at a U.S. Centers for Disease Control and Prevention lab, CBS News reported.

    So far all mosquitoes tested in Texas have been negative for the disease, according to a s...

    Public health officials are warning doctors, especially those in southern states, to be on the lookout for local spread of malaria after five cases have been reported in the United States in the past two months.

    This is the first time there has been local spread in this country since 2003. Four of the cases were found in Florida and the fifth was in Texas, the U.S. Centers for Disease Co...

    Florida has yet another new mosquito species in its midst that has migrated from the tropics, settling in at least three counties since 2018.

    It's not yet clear whether this one, called Culex lactator, will contribute to transmission of mosquito-borne viruses in the state, but scientists are concerned about the rate of new mosquitoes arriving in Florida.

    “There are about ...

    New research has confirmed that a three-dose malaria vaccine is both safe and effective in West African adults, including those previously exposed to malaria.

    Researchers at the University of Maryland Center for Vaccine Development and Global Health (CVD) led work on the Plasmodium falciparum sporozoite (PfSPZ) vaccine.

    The clinical trial, which included 80 participants, co...

    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...

    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...

    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...

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

    The approval was announced on Monday by the nonprofit Medicines for Malaria Venture (MMV), which helped develop the drug with GlaxoSmith...

    The first vaccine to protect against malaria has been endorsed by the World Health Organization (WHO) and could prevent the deaths of tens of thousands of children a year.

    Malaria kills about half a million people worldwide annually. Nearly all of those deaths occur in sub-Saharan Africa and include 260,000 children under the age of 5, The New York Times reported.

    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...

    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...

    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...
