Paul Ewald (Biologist)

Paul Ewald was an American biologist and researcher known for his work on the role of infectious agents in human disease. He proposed that many chronic illnesses, like heart disease and cancer, could be influenced by infections originally transmitted through close contact or other means. Ewald’s theories emphasized the importance of understanding how pathogens evolve and spread, which could lead to new ways of preventing or treating diseases. His work bridged biology and epidemiology, encouraging a broader view of disease development beyond genetics and lifestyle factors alone.
