It took three centuries for the germ theory to be completely developed and it was accepted in the nineteenth century (Thargard, 1997). Robert Koch made the first discovery of the cause of disease where he postulated bacterium as the cause of tuberculosis in 1882. In 1932, Prontosil drug was discovered by Gerhard Domagk as the drug that could eradicate the microbe that Koch had stipulated. Moreover, in 1944, streptomycin was discovered and proved to be the most efficient treatment in killing the microbe. This served as the genesis of treatment regimes which are currently aimed at treating the symptom, eradicating the cause, and changing the course of the disease hence altering the spread of the disease (Thargard, 1997). Latest technology in the twentieth century has led to a more pragmatic approach to spread of disease since it has led to the discovery of nutritional, genetic and immunological causes of disease. The discovery of these aspects has made individuals learn the roles that nutrition plays in preventing spread of disease and also the immunological aspects that sanitation plays in preventing the spread of disease. Genetically, sanitation has progressed since it has aided in the discovery of how some aspect in an individual predisposes them more to acquire infection compared to other individuals. Consequently, knowledge of the immune system has led to the development of vaccines that aid in the protecting the spread of disease.

Products are moved to carts from shelving and flow racks. There are about 20 totes in the carts that are utilized for the gathering of particular orders. The workers are guided to the specific location that the product is stored by the Jennifer system. The worker then communicates a check digit in order to confirm that this is the right location. The Jennifer system then advices the worker on the number of items to be picked and their specific loading tote position on the cart. This ensures picking accuracy that is accurate. The SI system provides software, which increases profitability, accuracy, and productivity via the optimization of distribution operations. It allows companies to maximize on efficiency for all the distribution centre’s picking systems. It does this via real time analysis of the storage and system for picking up in the building. It also determines each product’s proper technology and its optimal placing that will ensure the greatest productivity and efficiency. The system decreases walk time, eliminates bottlenecks, allows for increased labour effectiveness, and creates flexibility in operations and increases throughput. The slotting strategy reduces up to 50% of walk time, translating into increased savings on labour. DC Xcellerator is not only operated by a warehouse management system (Laudon & Carol 46). The system requires; the product information, the characteristics of the order, and the system for storage and picking available in the company building. A list is then generated that shows the moves to be made for slot products to reach the peak efficiency. A major advantage for the program is the minimal capital investment and dedication from the staff at the IT
