Anthrax is a serious infectious disease caused by the bacterium Bacillus anthracis. It primarily affects animals, especially herbivores like cattle, sheep, and goats, but can also infect humans. Anthrax can occur in three forms: cutaneous (skin), inhalation (lungs), and gastrointestinal (digestive system).
Cutaneous anthrax is the most common form and occurs when the bacteria enter the body through a cut or abrasion on the skin. It results in a black, painless sore with a surrounding swollen area. Inhalation anthrax is the most deadly form and occurs when spores are inhaled into the lungs. It initially presents with flu-like symptoms but can progress rapidly, leading to severe respiratory distress and potentially death. Gastrointestinal anthrax is rare and occurs when contaminated meat is consumed, causing symptoms like nausea, vomiting, and abdominal pain.
Anthrax spores can survive in the environment for long periods and can be found in soil and animal products. The disease is not contagious between humans, but it can be transmitted through contact with infected animals or their products. It can also be used as a biological weapon due to its ability to be easily disseminated and cause mass casualties.
Anthrax can be treated with antibiotics, especially if diagnosed early. Vaccines are available for animals, but there is also a vaccine for humans who are at high risk of exposure, such as laboratory workers or military personnel. Public health measures, such as proper handling and disposal of animal carcasses, can help prevent the spread of anthrax.
