Ancient pathogens

Ancient pathogens are disease-causing microorganisms like bacteria or viruses that existed in the past and can sometimes be revived from preserved remains, such as bones or mummies. These pathogens help scientists understand how diseases affected ancient populations and how they evolved over time. Studying them can reveal insights into historical outbreaks and may inform modern medicine and public health. Advances in DNA analysis allow researchers to identify and reconstruct these ancient microbes, offering a window into past health challenges and the development of infectious diseases throughout human history.
