As humans expanded their territory, they came into closer contact with microbes they might otherwise have never encountered. By storing food, humans attracted scavenging creatures such as rats and mice, which brought more microbes. Human expansion also resulted in the construction of more wells and ditches, which provided more standing water for disease-carrying mosquitoes. As technology allowed for wider travel and trade, new microbes could easily spread from one highly populated area to another.
