Emerging pathogens are infectious diseases whose incidence is increasing or threatening to increase. They include diseases that have developed antibiotic resistance or spread to new areas. Major emerging pathogens since the 1970s include HIV, Ebola, SARS, and antibiotic-resistant bacteria like MRSA. Factors driving emergence include increased travel and trade, antibiotic overuse, environmental changes, and evolving pathogens. Controlling emerging diseases requires early detection, diagnosis, treatment, and preventing transmission through vectors and contaminated food/water.
