    What is Chronic Wasting Disease (CWD)?

    Why in the News?

    A case of Chronic Wasting Disease (CWD) was confirmed in the US.

    About Chronic Wasting Disease (CWD)

    • CWD is a fatal, transmissible disease that affects the brain and central nervous system of deer, elk, and moose.
    • First identified in 1967, CWD is a prion disease where normal proteins misfold, leading to symptoms that eventually cause death.
    • Transmission occurs through animal-to-animal contact or contamination of feed or water by infected saliva or bodily waste.
    • Environmental contamination can occur through soil exposure from infected carcasses or bodily fluids.
    • High-risk areas include places where deer and elk gather closely, like feeding or watering sites.
    • Species affected: CWD does not naturally infect cows, other livestock, or pets.
    • Although no strong evidence exists that it can spread to humans, officials advise against eating meat from infected animals.

    Symptoms of CWD:

    • Symptoms: Drastic weight loss, lack of coordination, drooling, listlessness, and excessive thirst. Infected animals may also show drooping ears and lose their fear of humans.
      • Prevention: To prevent the spread of CWD, avoid handling or eating sick animals, use synthetic lures, dispose of carcass waste in landfills, and report any sick or unusual deer to local wildlife authorities.

    Features and Location:

    • DANA occurs when cold air from the Polar Regions separates from the polar jet stream and descends over the warmer Mediterranean Sea.
    • The contrast between cold air aloft and warm, moist air near the surface causes atmospheric instability, leading to the rapid formation of cumulonimbus clouds and intense thunderstorms.
    • It primarily affects Spain and Portugal but can also impact Italy, France, and other areas around the Mediterranean Sea.
    • This occurs in autumn and spring, as temperature variations are more pronounced during these seasons.
