What was the primary disease prevention in the renaissance period?

During the Renaissance period, primary disease prevention focused on maintaining good hygiene and sanitation, as well as the belief in the importance of a balanced diet and proper exercise. Public health measures included the establishment of quarantine practices in response to outbreaks, such as the Bubonic Plague. Additionally, the theory of miasma, which suggested that diseases were caused by "bad air," led to efforts to improve air quality in urban areas. Overall, the understanding of disease prevention was limited compared to modern standards, but these practices laid the groundwork for future public health initiatives.
