Bacteria unlike viruses can under go binary fission reproduce outside of a host.
In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates). The bacterial cell then elongates and splits into two daughter cells each with identical DNA to the parent cell. Each daughter cell is a clone of the parent cell.
When conditions are favorable, such as the right temperature and the availability of nutrients, some bacteria like Escherichia coli can divide every 20 minutes. This means that in just 7 hours one bacterium can generate 2,097,152 bacteria. After one more hour the number of bacteria will have risen to a colossal 16,777,216. That’s why we can quickly become ill when pathogenic microbes invade our bodies. (microbiology online)

C.diff (Clostridium difficile) once found predominantly in healthcare settings, has now spread to the workplace environment, placing employees with chronic illness at higher risk. C.diff creates spores, and it has an uncanny ability to contaminate the environment. Without proper cleaning and disinfection, C.diff can persist in the environment for months. The CDC has stated SuperBugs are continuing to make their presence known in the workplace. Methicillin-resistant Staphylococcus aureus “MRSA skin infections can now occur in any workplace. Some workplace settings have factors that make it easier for MRSA to be transmitted. These factors, referred to as the 5 C’s, are as follows: Crowding, frequent skin-to-skin Contact, Compromised skin (i.e., cuts or abrasions), Contaminated items and surfaces, and lack of Cleanliness.
