Before the microscope, people fought off disease with bouquets of flowers
In short: For centuries, humanity attributed infectious diseases to 'bad air.' This video explores how our understanding shifted from floral perfumes to the microscopic reality of bacterial pathogens.
Until approximately 200 years ago, the true cause of infectious disease remained a mystery. The prevailing theory suggested that illness was caused by 'bad air,' leading people to carry sweet-smelling flowers as a preventative measure against infection.
The invention of the microscope and subsequent scientific experimentation allowed for the discovery of pathogens like bacteria and viruses. This shift in perspective provides the foundation for modern medicine's approach to human disease.
