How long has disease been around?

The origins of disease date back to the emergence of life on Earth. Infectious agents, such as viruses, bacteria, fungi, and parasites, have existed for millions of years, potentially coevolving with their hosts. The earliest evidence of disease in humans comes from the skeletal remains of ancient hominids, which show signs of infections, trauma, and degenerative conditions. As human populations grew and civilizations developed, so did the spread and diversification of diseases, facilitated by factors such as trade, travel, and urbanization. Throughout history, pandemics and epidemics have had profound impacts on human societies, shaping healthcare practices, cultural beliefs, and scientific advancements in the pursuit of understanding and controlling diseases.
