Immunodeficiency is a condition that occurs when the body's protective barriers are broken, leading to easy invasion of pathogens such as bacteria, viruses or parasites. Immune system deficiencies will reduce the body's resistance, increasing the risk of disease affecting health.

Anthrax bacteria, scientifically known as Bacillus anthracis, are gram-positive bacilli. They exist in nature in the form of spores, so their survival time can last for decades. Bacillus anthracis causes anthrax in both animals and humans. The human body can be infected with anthrax bacteria through different routes such as: respiratory tract, skin, digestive tract, or needle injection. The severity and symptoms of the disease depend on each route of bacterial infection.

Anthrax is an acute infectious disease with three main routes of infection: through the skin, through the digestive tract and through the respiratory tract. Inhalation anthrax is the most dangerous form with a mortality rate of up to 90%. Therefore, equipping yourself with the necessary knowledge to understand and prevent anthrax is extremely important.
