Want to learn more about the global impact of infectious diseases? Check out our detailed infographic below filled with eye-opening statistics.
Throughout history, infectious diseases have had a devastating impact on humankind. Up until the 1920s, they were the leading cause of death in the United States. Today, despite remarkable advances in medical research and treatments during the 20th century, infectious diseases still cause approximately one in every four deaths worldwide.
Changes in human demographics, behavior and land use are altering the transmission dynamics of these infectious diseases worldwide. Environmental causes that contribute to the spread of disease include animal- and insect-borne pathogens, airborne pathogens, skin-to-skin transmission, food- and water-borne infections, and transmission from body fluids or contaminated objects.
Due to these changes over the last few decades, it has become apparent that new infectious diseases will emerge, old threats will re-emerge and microbes are increasingly prone to outsmarting efforts to contain or eradicate them.
