Germinal (theory)

Germinal theory, developed in the late 19th century, posits that certain diseases are caused by specific microorganisms—tiny living organisms like bacteria or viruses. It challenged earlier ideas that illnesses resulted from miasma or bad air. According to this theory, each disease is linked to a particular germ, and understanding these germs helps in preventing and treating illnesses. This concept laid the foundation for modern microbiology and infection control, emphasizing that microbial agents are the root cause of many diseases, which can be managed through hygiene, sanitation, and medical interventions.
