Malignant pustule, also known as Anthrax, is a serious bacterial infection that affects both animals and humans. This disease can be fatal if not treated promptly. Some synonyms for malignant pustule include wool-sorter's disease, splenic fever, and charbon. Common symptoms of the disease include the development of painful skin lesions, fever, swelling in lymph nodes, and difficulty breathing. It is important to seek medical attention immediately if you suspect that you or someone you know has contracted this illness. Fortunately, there are effective treatments for malignant pustule available, including antibiotics and antitoxins, which can lead to a full recovery if administered early enough.
