Trivial Facts

  1. Is anthrax really lethal?
    1. Anthrax can be found naturally in soil (especially agricultural regions) and commonly affects domestic and wild animals around the world.
    2. Anthrax is not contagious, which means you can’t catch it like the cold or flu.
    3. People get infected with anthrax when spores get into the body. When anthrax spores get inside the body, they can be “activated.” When they become active, the bacteria can multiply, spread out in the body, produce toxins (poisons), and cause severe illness.
    4. Anthrax can be treated with antibiotics.
    5. Isolated cases are not uncommon in Hong Kong. A total of four reported cases since 1982, with two fatalities.
